A particular fruit's weights are normally distributed, with a mean of 753 grams and a standard deviation of 9 prams if you pick 3 fruits at random, then of the time, their mean weight will be greater than how many grams? Give your answer to the nearest grami.

Answers

If you pick 3 fruits at random, the mean weight will be greater than 757 grams approximately 1.26% of the time.


To solve this problem, we need to use the properties of the normal distribution. We know that the weights of the fruit are normally distributed with a mean of 753 grams and a standard deviation of 9 grams.
The mean of the sample of 3 fruits will also be normally distributed with a mean of 753 grams and a standard deviation of 3 grams (since we are dividing by the square root of the sample size).

To find the probability that the mean weight of the sample of 3 fruits will be greater than a certain amount, we need to convert this amount to a z-score using the formula:
z = (x - μ) / (σ / √n)

where x is the amount we are interested in, μ is the mean, σ is the standard deviation, and n is the sample size (in this case, 3).

In this case, we want to find the z-score for a mean weight of 757 grams:

[tex]z = \frac{(757 - 753)}{\frac{9}{\sqrt{3}} }} =1.26[/tex]

We can use a standard normal distribution table or calculator to find that the probability of getting a z-score greater than 1.26 is approximately 0.0985, or 9.85%. However, since we are interested in the probability that the mean weight will be greater than 757 grams (not just greater than the mean), we need to add half of the probability of getting exactly 757 grams (which is the mode of the distribution) to this value.
Since the normal distribution is symmetrical, the probability of getting exactly 757 grams is the same as the probability of getting exactly 749 grams (which is the mean minus one standard deviation). Using the same formula as before, we can find the z-score for a weight of 749 grams:

z =  \frac{(749 - 753)}{\frac{9}{\sqrt{3}} }} =-1.26[/tex]

The probability of getting a z-score less than -1.26 is also approximately 0.0985, so the probability of getting exactly 757 grams is approximately 0.197. Half of this value is 0.0985, which we add to the probability of getting a z-score greater than 1.26 to get the final answer:
0.0985 + 0.0985 = 0.197
So the probability of getting a mean weight greater than 757 grams is approximately 0.0985 + 0.197 = 0.2965, or 29.65%.

To convert this probability to weight, we can use a standard normal distribution table or calculator to find the z-score corresponding to a probability of 29.65%. This is approximately 0.56. Using the same formula as before, we can solve for x:

\frac{(x - 753)}{\frac{9}{\sqrt{3}} }} =0.56[/tex]

x ≈ 757.23

So if you pick 3 fruits at random, their mean weight will be greater than 757 grams approximately 1.26% of the time.

The position of a particle moving in the xy-plane is given by the parametric functions x(t) and y(t) for which x′(t)=t sin t and y′(t)=5e−3t+2 What is the slope of the tangent line to the path of the particle at the point at which t=2?

Answers

Answer:

To find the slope of the tangent line to the path of the particle at the point where t = 2, we first need to find the values of x(2) and y(2), as well as their derivatives x'(2) and y'(2).

Using the given parametric functions, we can find:

x(2) = ∫ x'(t) dt = ∫ t sin(t) dt = -t cos(t) + sin(t) + C

where C is the constant of integration.

Since we want x(2), we can evaluate the above expression at t = 2:

x(2) = -2 cos(2) + sin(2) + C

Similarly, we can find:

y(2) = ∫ y'(t) dt = ∫ (5e^(-3t) + 2) dt = (-5/3)e^(-3t) + 2t + C'

where C' is the constant of integration.

Again, since we want y(2), we can evaluate the above expression at t = 2:

y(2) = (-5/3)e^(-6) + 4 + C'

Now we can find the derivatives x'(2) and y'(2) by taking the derivative of x(t) and y(t), respectively, and evaluating them at t = 2:

x'(2) = 2 sin(2) - cos(2)

y'(2) = (5/3)e^(-6)

Therefore, at t = 2, the particle is at the point (x(2), y(2)) = (-2 cos(2) + sin(2) + C, (-5/3)e^(-6) + 4 + C'), and the slope of the tangent line to the path of the particle at this point is given by:

dy/dx = (dy/dt)/(dx/dt) = y'(2)/x'(2)

Substituting the values we found:

dy/dx = [(5/3)e^(-6) + 4 + C']/(2 sin(2) - cos(2))

Since we don't have enough information to find the value of C', we cannot find an exact value for the slope. However, we can simplify the expression by using the trigonometric identities:

sin(2) = 2 sin(1) cos(1)

cos(2) = cos^2(1) - sin^2(1)

where we let t = 1 for simplicity. Then, we can substitute these expressions and simplify:

dy/dx = [(5/3)e^(-6) + 4 + C']/(4 sin(1) cos(1) - cos^2(1) + sin^2(1))

dy/dx = [(5/3)e^(-6) + 4 + C')/(4 sin(1) cos(1) - 1)

Therefore, the slope of the tangent line to the path of the particle at the point where t = 2 is given by the above expression.

Step-by-step explanation:

The slope of the tangent line to the path of the particle at the point where t=2 is approximately 1.55. To find the slope of the tangent line to the path of the particle at the point where t=2,

we need to use the derivatives of x(t) and y(t).

First, we can find the slope of the tangent line by using the formula:

slope = dy/dx = (dy/dt)/(dx/dt)

So, we need to find both dy/dt and dx/dt.

Given that x′(t)=t sin t, we can find dx/dt by taking the derivative of x(t):

dx/dt = x′(t) = t sin t

Given that y′(t)=5e−3t+2, we can find dy/dt by taking the derivative of y(t):

dy/dt = y′(t) = 5e−3t+2

Now, we can find the slope of the tangent line at t=2 by plugging in these values:

slope = (dy/dt)/(dx/dt) = (5e−3t+2)/(t sin t) = (5e−6+2)/(2 sin 2)

Therefore, the slope of the tangent line to the path of the particle at the point where t=2 is approximately 1.55.

Plane A has just 1 ton of fuel left and has requested plane B to refuel it. Plane B has 21 tons of fuel. Fuel transfer happens at the rate of 1 ton per minute. Use this information as you work through the activity and find how long it will take to refuel plane A until both planes have the same amount of fuel. Let x be the time in minutes and y be the amount of fuel in tons. The equation y = x + 1 represents the quantity of fuel with respect to time in plane A, and y = -x + 21 represents the quantity of fuel with respect to time in plane B. For each equation, find two points that satisfy the equation

Answers

The time for which plane B will take to refuel plane A is equals to 10 minutes. The two points who satisfy the equation, y = x + 1, are (0, 1), (-1,0). The two points who satisfy the equation, y = -x + 21, are (0,21), (21,0).

We have a fuel left in Plane A = 1 ton

fuel left in Plane B = 21 tons

Fuel transfer rate = 1 ton per minute

In order that for them to have the same amount of fuel, We add up the fuel left in Plane A and Plane B = 21 + 1 = 22 tons. This implies each plane will have fuel of 11 tons. Time that plane B will take to refuel plane A until both planes have the same amount of fuel is calculated by : Plane B will transfer 10 tons of fuel to A.

Plan A has a total of 11 tons. Since, the transfer rate = 1 ton per minute

=> 1 ton will transfer in 1 minute

So, 10 tons fuel will need 10 minutes. Hence, required time value is 10 minutes. Now, The equation for quantity of fuel with respect to time in plane A is, y = x + 1 --(1). If x = 0 => y = 1

and y = 0 => x = -1. So, (0, 1) and (-1,0).

The equation for quantity of fuel with respect to time in plane B is, y = -x + 21 --(2). For it, x = 0 => y = 21 and y= 0 => x = 21. Hence, two points that satisfy the equation(1) and equation(2) are (0, 1), (-1,0) and (0,21), (21,0) respectively.

Compare these values to those you would get from the distribution line that you draw through the data by eye.

Answers

Hi, I'm glad to help you with this question. To determine if the normal distribution gives a reasonable approximation using the given data, we need to calculate the mean and standard deviation. Here are the steps:

1. Calculate the mean (average): Add all the data points together and divide by the number of data points.
(71+42+77+84+46+93+94+63+82+88+57+32+79+67+68+83+60+65+58+70) / 20 = 1380 / 20 = 69

Mean = 69

2. Calculate the standard deviation: First, find the difference between each data point and the mean, square the differences, and then find the average of those squared differences. Finally, take the square root of that average.
a. Differences from the mean: (-2, 27, 8, 15, -23, 24, 25, -6, 13, 19, -12, -37, 10, -2, -1, 14, -9, -4, -11, 1)
b. Squared differences: (4, 729, 64, 225, 529, 576, 625, 36, 169, 361, 144, 1369, 100, 4, 1, 196, 81, 16, 121, 1)
c. Average of squared differences: (4520) / 20 = 226
d. Square root of the average: √226 ≈ 15.03

Standard Deviation ≈ 15.03

Now that we have the mean (69) and the standard deviation (15.03), you can compare these values to the distribution line that you draw through the data by eye. If the distribution line follows a bell-shaped curve with the mean at the center and the data points spread around it following the standard deviation, then the normal distribution provides a reasonable approximation for this data set.

The factors to the given expression are -1(x+3)(x-8)

The x-intercepts of the quadratic relationship are -3, 8. When we write an expression in its factors and multiplying those factors gives us the original expression, then this process is known as factorization.

How do we factorize the given expression?

We equate the given expression to f(x)

   (-[tex]x^{2}[/tex] + 5x + 24) = f(x)

⇒ -1([tex]x^{2}[/tex] - 5x - 24) = f(x)

⇒ -1([tex]x^{2}[/tex] - (8-3)x - 24) = f(x)

⇒ -1([tex]x^{2}[/tex] + 3x - 8x -24) = f(x)

⇒ -1(x(x+3) -8(x+3)) = f(x)

⇒ -1(x+3)(x-8) = f(x)

∴The factor to the given expression is -1(x+3)(x-8)

How do we find the x-intercepts?

We equate f(x) = 0 to find the x-intercepts.

⇒ -1(x+3)(x-8) = 0

A pool measuring 10 meters by 20 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the path combined is 1200 square meters, what is the width of the path?

Answers

Answer:

The area of the pool is 10*20 = 200 square meters. Let's assume the width of the path is x. Then the dimensions of the entire region would be (10+2x) by (20+2x). The area of the entire region would be (10+2x)*(20+2x) = 400 + 60x + 4x^2. We know that the area of the pool and the path combined is 1200 square meters. So we can set up the equation as follows:

200 + 1200 = 400 + 60x + 4x^2

Simplifying the equation, we get:

4x^2 + 60x - 1000 = 0

Dividing both sides by 4, we get:

x^2 + 15x - 250 = 0

Factoring the equation, we get:

(x + 25)(x - 10) = 0

x = 10 or x = -25

Since the width of the path can't be negative, the width of the path is 10 meters.

Question 1:1 11 marks] It has been claimed that more than 40% of all shoppers can identify a highly advertised trademark. 16. in a random sample, 13 of 18 shoppers were able to identify the trademark. At the a = 0.01 level of significance that is there enough evidence to reject the claim?

Answers

The proportion of shoppers who can identify the highly advertised trademark is significantly higher than 40% at the 0.01 level of significance.

Let's break it down step-by-step using the provided information:

1. Hypotheses: - Null hypothesis (H0): p = 0.40 (40% of all shoppers can identify the trademark) - Alternative hypothesis (Ha): p > 0.40 (more than 40% of all shoppers can identify the trademark)

2. Level of significance: - α = 0.01

3. Sample information: - n (sample size) = 18 - x (number of successful identifications) = 13 - p-hat (sample proportion) = x / n = 13 / 18 = 0.7222 4. Test statistic

calculation: - We'll use a one-sample z-test for proportions. - z = (p-hat - p) / sqrt((p * (1 - p)) / n) - z = (0.7222 - 0.40) / sqrt((0.40 * (1 - 0.40)) / 18) - z ≈ 2.88 5. Decision: - Since α = 0.01, we'll compare our test statistic to the critical value from the z-table, which is 2.33 for a one-tailed test. - Our test statistic, z ≈ 2.88, is greater than the critical value of 2.33.

Conclusion: Since our test statistic is greater than the critical value at the 0.01 level of significance, we have enough evidence to reject the null hypothesis (H0). This means that there is sufficient evidence to support the claim that more than 40% of all shoppers can identify a highly advertised trademark.

Answers

The correct answer is d. The significance level tests for the coefficients are not valid.

Multicollinearity is a statistical term that refers to the presence of high correlation among predictor variables in a regression model. This can cause issues in the model, such as unstable or unreliable coefficients, and can lead to incorrect conclusions about the relationships between the predictors and the response variable.

When multicollinearity is present, the R-squared value of the model can become inflated because the model is able to explain more of the variation in the response variable due to the high correlation among the predictor variables. This can give the impression that the model is a good predictor when in fact it may not be. Additionally, multicollinearity can cause the F-test significance level to be low, indicating that the model is a good fit, even though the individual coefficients may not be statistically significant.

Multicollinearity can cause inflated R-squared values and low F-test significance levels. However, it does not necessarily mean that the model is a poor predictor. The interpretation of coefficients may also be affected by multicollinearity.

However, the most significant issue with multicollinearity is that it can lead to unreliable significance tests for individual coefficients, making it difficult to determine which predictors are contributing significantly to the model.

Answers

Henry predicted that he got 31 questions right, but he actually got 31 - 6 = 25 questions right.

Henry predicted that he got 19 questions wrong, but he actually got 12 questions wrong.

Therefore, Henry predicted that he would get 31 + 19 = 50 questions, but he actually got 25 + 12 = 37 questions correct.

To find the percentage accuracy of Henry's predictions, we can use the formula:

percentage accuracy = (number of correct predictions / total number of predictions) x 100%

In this case, the number of correct predictions is 37 out of 50, since Henry got 37 questions right out of the 50 total questions. The total number of predictions is 50, since Henry predicted the outcome of all 50 questions.

Answers

Using Table B at line 133, the consumers assigned to treatment 1 are those numbered 4, 5, 7, 1, and 8.

The table displaying the treatments in a design with two factors would be: | | Ambient scent | |----------|--------------| | Product density | Seashore (A) | Enclosed space (B) | No scent | | Jam-packed | 2 | 1 | 3 | | Minimally stocked | 4 | $ | 6 |

To randomly assign the 30 subjects to the six treatments, we would first label the subjects from 01 through 30. Then, we would use Table B starting at line 133 to randomly select the appropriate number of subjects for each treatment. For example, to randomly assign 5 consumers to treatment 1, we would use Table B to select 5 numbers from 01 through 30, and label those subjects as treatment 1. We would then repeat this process for each of the six treatments. An example of this would be: Assign = 5 consumers to each of the six treatments. Label the subjects from 01 through 30. Randomly select 5 numbers for treatment 1, then 5 of the remaining consumers for treatment 2, and so on. Using Table B at line 133, the consumers assigned to treatment 1 are those numbered 4, 5, 7, 1, and 8.

Answers

The time taken by the train to pass the man is 54 seconds

To find the time taken by the train to pass a man standing near the railway line, we need to convert the train's speed to meters per second and then use the formula time = distance/speed.

1. Convert the speed of the train from km/hr to m/s: 40 km/hr * (1000 m/km) / (3600 s/hr) = 40000/3600 = 40/3.6 = 10/0.9 = 100/9 m/s.

2. Now, use the formula: time = distance/speed. The distance is the length of the train (600 m) and the speed is 100/9 m/s.

time = 600 m / (100/9 m/s) = 600 * 9 / 100 = 54 seconds.

Therefore, the time taken by the train to pass the man is 54 seconds (Option A).

You started your day out with $120 in your bank account. You paid your electricity bill that was $67. Then, you went out with friends and spent $44 on your night out. On your way home, you stopped and purchased gas for $35. How much do you have to deposit into your bank account to not receive an overdraft fee?

Answers

You need to deposit at least $74 into your bank account to avoid an overdraft fee.

We have,

Start with the initial balance = $120

Subtract the first expense, the electricity bill = $120 - $67 = $53

Subtract the second expense, the night out with friends = $53 - $44 = $9

Subtract the third expense, the gas purchase = $9 - $35 = -$26

Now,

Since the remaining balance is negative, you would receive an overdraft fee if you left it at this amount.

To avoid the overdraft fee, you need to deposit enough money to bring your account balance back to $0 or higher.

To do this, you need to add the absolute value of the negative balance to your desired minimum balance, which in this case is:

$0 = |-26| + $0 = $26

Therefore,

You need to deposit at least $74 into your bank account to avoid an overdraft fee.

Two ships leave a port at 9 a.m. One travels at a bearing of N 53° W at 12 miles per hour, and the other travels at a bearing of S 67° W at s miles per hour. (a) Use the Law of Cosines to write an equation that relates s and the distance d between the two ships at noon. (b) Find the speed s that the second ship must travel so that the ships are 42 miles apart at noon. (Round your answer to two decimal places.) mi/h

Answers

a) Using the Law of Cosines for this triangle, we can write the equation:
d² = (36)² + (3s)² - 2(36)(3s)cos(60°)

b) The second ship must travel at approximately 4.24 miles per hour to be 42 miles apart from the first ship at noon.


(a) To write an equation that relates the speed s and the distance d between the two ships at noon using the Law of Cosines, we first need to determine the distance each ship has traveled by noon. Since they leave at 9 a.m. and we're interested in the distance at noon, they travel for 3 hours.

Ship 1:
Speed: 12 miles per hour
Distance traveled: 12 miles/hour * 3 hours = 36 miles

Ship 2:
Speed: s miles per hour
Distance traveled: s miles/hour * 3 hours = 3s miles

Now, we can form a triangle where Ship 1 travels 36 miles, Ship 2 travels 3s miles, and the distance between them (d) is the third side. The angle between Ship 1 and Ship 2 is 180° - (53° + 67°) = 60°.

Using the Law of Cosines for this triangle, we can write the equation:
d² = (36)² + (3s)² - 2(36)(3s)cos(60°)

(b) To find the speed s that the second ship must travel so that the ships are 42 miles apart at noon, we can plug d = 42 into our equation from part (a) and solve for s.

42² = (36)² + (3s)² - 2(36)(3s)cos(60°)

Solving for s, we get:
s ≈ 4.24 miles per hour (rounded to two decimal places)

So, the second ship must travel at approximately 4.24 miles per hour to be 42 miles apart from the first ship at noon.

Solve each system by using elementary row operations on the equations or on the augmented matrix. Follow the systematic elimination procedure described in this section.
2x 1+4x 2=−4 5x1+7x 2=11

Answers

The solution to the system is [tex]$\$\left(x_{-} 1, x_{-} 2\right)=(4,-3) \$$[/tex].

To solve the system, we can use the method of elimination or Gaussian elimination.

We start by writing the system in augmented matrix form:

[tex]$$\left[\begin{array}{cc|c}2 & 4 & -4 \\5 & 7 & 11\end{array}\right]$$[/tex]

We can eliminate the [tex]$\$ x_{-} 1 \$$[/tex] variable from the second equation by subtracting 5 times the first equation from the second:

[tex]$$\left[\begin{array}{cc|c}2 & 4 & -4 \\5-5(2) & 7-5(4) & 11-5(-4)\end{array}\right] \Rightarrow\left[\begin{array}{cc|c}2 & 4 & -4 \\-3 & -13 & 31\end{array}\right]$$[/tex]

Next, we can eliminate the [tex]$\$ x_{-} 2 \$[/tex]$ variable from the first equation by subtracting twice the second equation from the first:

[tex]$$\left[\begin{array}{cc|c}2-2(-13) & 4-2(7) & -4-2(31) \\-3 & -13 & 31\end{array}\right] \Rightarrow\left[\begin{array}{cc|c}28 & -10 & -66 \\-3 & -13 & 31\end{array}\right]$$[/tex]

We can simplify this further by dividing the first row by 2 :

[tex]$$\left[\begin{array}{cc|c}14 & -5 & -33 \\-3 & -13 & 31\end{array}\right]$$[/tex]

Now we can solve for [tex]$\$ x_{-} 2 \$$[/tex] in terms of [tex]$\$ x_{-} 1 \$$[/tex] by multiplying the first equation by 13 and adding it to the second equation:

[tex]$$13(14) x_1-13(5) x_2-13(33)-3(-13) x_1-3(-13) x_2=13(31)-3(14) x_1$$[/tex]

Simplifying:

[tex]$$\begin{aligned}& 169 x_1-91 x_2-429+39 x_1+39 x_2=403 \\& 208 x_1=832 \\& x_1=4\end{aligned}$$[/tex]

Substituting back into the first equation, we get:

[tex]$$2(4)+4 x_2=-4 \Rightarrow x_2=-3$$[/tex]

Therefore, the solution to the system is [tex]$\$\left(x_{-} 1, x_{-} 2\right)=(4,-3) \$$[/tex].

Although the Cold War never did escalate from tension to real violence between the two countries, people in the United States worried that the Soviets might attack with a nuclear bomb. To prepare for such an event, elementary and high school students performed emergency drills at school, just as we might do fire or other safety drills today. The most common drill was called Duck and Cover.In a duck and cover drill, a student drops to the floor and gets under something, like a desk. Then they lie face-down, curl up, and cover the head and neck with a jacket, book, or even their hands. The goal of this drill was to protect against several dangerous side effects of a nuclear blast. The force of the explosion could create immense amounts of heat. It could also cause windows to shatter. Keeping ones face on the floor could prevent burns and protect it from flying pieces of sharp glass.The United States government worked hard to teach as many people about the duck and cover drill as possible. In 1951 they also released a short video, also titled Duck and Cover, written for children in schools. This film featured a cartoon turtle named Bert, who ducked and covered whenever he saw a bright flash of light. Schools encouraged teachers to yell, Drop! in the middle of a lesson in order to see if students were prepared at any moment. Some cities even made small metal dog tags for children to wear, so that they could be identified in case a bomb killed them.The government also wanted to help adults know what to do in an emergency. They released informational pamphlets that explained the duck and cover position and other strategies to survive a nuclear attack. They sent trucks around the country to show the videos and pass out booklets of information. Stores and magazines advertised bomb shelters that people could buy to put in their backyards. Cities set up public fallout centers where people could go to run away from atomic radiation, and they also stored large amounts of food and installed emergency broadcast systems in public places. The federal government estimated that all these efforts would save 27 million people.Writers and scholars disagree about whether these programs were good or bad. Some say they promoted a healthy awareness of a real threat to the United States. Others say they gave people an unnecessary fear of crisis. School drills and other nuclear preparedness programs slowly went away in the 1960s, as U.S. leaders began to talk more openly with Soviet leaders. 1. which of the following best describes how the fomc conducts monetary policy to increase employment during a recession to achieve its maximum employment objective?a.Lowering interest ratesb.Expanding the money supplyc.Providing forward guidanced.Implementing unconventional monetary policy measures 1. identify the most accurate way to classify the type of caries seen on the maxillary anterior teeth.
