Step-by-step explanation:

The probability of selecting a boy from the class on the first draw is 7 boys out of 17 students total, or 7/17.

After the first boy is selected, there will be 6 boys and 10 girls left in the class.

So the probability of selecting a boy on the second draw, given that a boy was already selected on the first draw, will be 6 boys out of 16 remaining students, or 6/16.

To find the probability that both students selected are boys, we can multiply the probabilities of selecting a boy on the first and second draws:

P(boy and then boy) = P(boy on first draw) x P(boy on second draw | boy on first draw)

P(boy and then boy) = (7/17) x (6/16)

P(boy and then boy) = 21/136

Therefore, the probability of selecting two boys from Mr. Smith's class is 21/136.

[tex] \frac{7}{17} \times \frac{6}{16} = \frac{7}{17} \times \frac{3}{8} = \frac{21}{136} [/tex]

The student's test score is 0.76 standard deviations above the mean of the class.

A z-score is a measure of how many standard deviations a data point is from the mean of the data set. It is calculated by subtracting the mean from the data point and dividing by the standard deviation. In this case, the teacher wants to convert the test scores into z-scores relative to the mean and standard deviation of the students in the class.

The formula for calculating a z-score is:

z-score = (data point - mean) / standard deviation

Using the mean and standard deviation provided in the question, the teacher can calculate the z-score for each student's test score by plugging in the values into the formula. For example, if a student scored 150 on the test, their z-score would be:

z-score = (150 - 130) / 26.2
z-score = 0.76

This means that the student's test score is 0.76 standard deviations above the mean of the class. The teacher can use this information to understand how each student's test score compares to the rest of the class.

3.876 x 10^7 in standard form is 38,760,000.

Step-by-step explanation:

Answer:

38,760,000

Step-by-step explanation:

To write 3.876 x 10^7 in standard form, you need to move the decimal point to the left or right, depending on whether the exponent is positive or negative. In this case, the exponent is positive, so you need to move the decimal point 7 places to the right.

Starting with 3.876, move the decimal point to the right 7 places to get:

38,760,000

So 3.876 x 10^7 in standard form is 38,760,000.

64,000÷10 to the fourth power is equal to 0.64 × 10⁴

In mathematics, an algebraic expression is a combination of variables, constants, and mathematical operations, such as addition, subtraction, multiplication, and division, that represents a quantity or a relationship between quantities.

To solve this, we need to remember the order of operations, which is parentheses, exponents, multiplication and division (performed left to right), and addition and subtraction (also performed left to right).

First, we need to calculate 10 to the fourth power:

10 to the fourth power means 10 multiplied by itself four times:

10⁴ = 10,000

Now we can substitute that value into the original expression:

64,000 ÷ 10,000 =  0.64 × 10⁴

Therefore, 64,000÷10 to the fourth power is equal to  0.64 × 10⁴

if it is a square, the sides are equal. The diagonal will divide the square into 2 isosceles right triangles with diagonal is the hypotenuse

Pythagorean theorem: c^2 = a^2 + b^2

since a = b in isosceles right triangle

c^2 = 2a^2

18 = 2a^2

a^2 = 18/2 = 9

a = √9 = 3

A(8) = 9/7A(-5) = -1/3A(3/1) = 2A(-71/1) = -5/36

Function: A(t) = (t+1)/(t-1)For the given function A(t), the following values are to be calculated: A(8), A(-5), A(3/1), and A(-71/1)A(8):We need to substitute t=8 in the function. A(8) = (8+1)/(8-1) = 9/7Therefore, A(8) = 9/7A(-5):We need to substitute t=-5 in the function. A(-5) = (-5+1)/(-5-1) = -1/3Therefore, A(-5) = -1/3A(3/1):We need to substitute t=3/1 in the function. A(3/1) = (3/1+1)/(3/1-1) = (4)/(2/1) = 4*1/2 = 2Therefore, A(3/1) = 2A(-71/1):We need to substitute t=-71/1 in the function. A(-71/1) = (-71/1+1)/(-71/1-1) = (-70/1)/(-72/1) = (-5/36)Therefore, A(-71/1) = -5/36Therefore, the respective answers for the given values of the function A(t) are as follows: A(8) = 9/7A(-5) = -1/3A(3/1) = 2A(-71/1) = -5/36

i) The expression relating price and output assuming it is linear is Price per unit = -20 × Number of units sold + c.

ii) The total cost function, assuming it is linear is 2000 + 10 × Number of units sold.

iii)  The business woman need to produce 114 products to achieve breakeven.

(i) The expression relating price and output assuming it is linear can be written as:

Price per unit = m × Number of units sold + c

where m is the slope of the line and c is the y-intercept.

We can find the slope by using the two points (20, 300) and (13, 440):

m = (440 - 300) / (13 - 20) = 140 / (-7) = -20

So, the expression relating price and output is:

Price per unit = -20 × Number of units sold + c

(ii) The total cost function assuming it is linear can be written as:

Total cost = Fixed cost + Variable cost per unit × Number of units sold

Given that the fixed cost of production is GH₵2,000 with a variable cost per unit of GH¢10, the total cost function can be expressed as:

Total cost = 2000 + 10 × Number of units sold

(iii) To find the level of production at which the business woman will breakeven, we need to find the point at which the total cost equals the total revenue. Since the total revenue is simply the product of the price per unit and the number of units sold, we can set these two equations equal to each other:

Price per unit × Number of units sold = Total cost

Substituting the expressions we found in parts (i) and (ii), we get:

(-20 × Number of units sold + c) × Number of units sold = 2000 + 10 × Number of units sold

Simplifying and solving for the number of units sold, we get:

20 × Number of units sold^2 - 20c × Number of units sold - 2000 = 0

Using the quadratic formula, we get:

Number of units sold = (-(-20c) ± sqrt((-20c)^2 - 4 × 20 × (-2000))) / (2 × 20)

Simplifying, we get:

Number of units sold = (c + sqrt(c^2 + 2000)) / 2

Since we know that the business woman can sell 300 units a day at a price of GH¢20 and 440 units a day at a price of GH¢13, we can set up a system of equations to solve for the y-intercept, c:

-20 × 300 + c = 20c + 2000

-20 × 440 + c = 13c + 2000

Solving this system of equations, we get:

c = 2400/3 ≈ GH₵800

Therefore, the level of production at which the business woman will breakeven is:

Number of units sold = (800 + sqrt(800^2 + 2000)) / 2 ≈ 113.7 units

She should produce at least 114 units to breakeven.

The correct answer is (A): "its sampling distribution is centered exactly at the parameter it estimates."

An estimator is a statistic that is used to estimate an unknown parameter in a population. A point estimator is a single value that is used to estimate the population parameter. The goal of a point estimator is to provide an estimate that is as close to the true value of the parameter as possible.

One way to evaluate the quality of a point estimator is to look at its bias, which is the difference between the expected value of the estimator and the true value of the parameter it is estimating. An estimator is unbiased if its expected value is equal to the true value of the parameter it estimates. In other words, an unbiased estimator is centered exactly at the parameter it estimates.

In the context of the given problem, the sample mean of weekly computer usage time (8.5 hours) is a point estimator for the population mean weekly computer usage time. To evaluate whether this estimator is unbiased, we would need to look at its sampling distribution and check whether its expected value (i.e., the mean of the sampling distribution) is equal to the true population mean.

The current drawn by R2 is 3.333A or 3333mA in parallel combination in ohms.

In a parallel combination, the voltage across both resistors is the same. However, the current is divided between the two resistors based on their individual resistances. Using Ohms law (V = IR), we can find the voltage across the resistors:

According to the specific resistances of the resistors in a parallel circuit, the current is distributed among them. More current will flow through the resistor with the lower resistance than the one with the greater resistance. This is due to the fact that the lower resistance provides less resistance to the current flow. In this instance, R1 will draw more current than R2 since it has a lower resistance than R2.

V = IR1 = (10A)(5Ω) = 50V

V = IR2 = (I)(15Ω)

We can find current I by solving this particular equation:

I = V/R2 = (50V)/(15Ω) = 3.33A

Convert this ampere value to milliamps, in which we have to multiply by 1000:

I = 3.33A * 1000 = 3333mA or 3.333A

If, when we look at the data, we find that more than half the students spend 2 1/2 hours or more on homework, then Daniel is correct. Conversely, if more than half the students spend less than 2 1/2 hours on homework, then Liz is correct. It is important to note that the answer may depend on the sample size of the data we are looking at.

If the sample size is small, then it may be difficult to definitively answer the question. However, if the sample size is large, then it may be possible to provide a definite answer. In conclusion, to determine who is correct, we must look at the actual data. If the sample size is large enough, then it may be possible to definitively answer the question of who is correct.

Daniel says that more than half of the students spent 2.5 hours or more on homework, while Liz says more than half of the students spent less than 2.5 hours on homework. Liz's assertion is correct. So, Liz is correct since more than half of the students spent less than 2.5 hours on homework.

The point on the number line that is 1/4 of the way from point 0 to -3 is located at the point 3/4.

What is a number line?

A number line is a straight line that represents the real numbers as points or marks on the line. The numbers increase from left to right, and each point on the line corresponds to a specific number.

To find the point on the number line that is 1/4 of the way from point 0 to -3, we can use the following formula:

point = starting point + fraction of distance * total distance

The starting point is 0, and the total distance is the distance between 0 and -3, which is 3. So the total distance is 3.

Now, we need to find the fraction of the distance that is 1/4 of the total distance. This can be written as:

fraction of distance = 1/4

So the formula becomes:

point = 0 + 1/4 * 3

Simplifying the expression, we get:

point = 3/4

Therefore, the point on the number line that is 1/4 of the way from point 0 to -3 is located at the point 3/4.

If Jasper and Corey have saved up a total of $78.0 and Jasper has saved 6 dollars more than twice as much as Corey, Corey has saved $24, for a total of $78.

Let's use C to represent the amount of money Corey has saved.

We know that Jasper has saved 6 dollars more than twice as much as Corey, so we can write an equation to represent this relationship:

J = 2C + 6

where J is the amount of money Jasper has saved.

We also know that the total amount of money saved by Jasper and Corey is $78, so we can write another equation to represent this:

J + C = 78

Now we can substitute the first equation into the second equation to get an equation with only one variable:

(2C + 6) + C = 78

Simplifying the equation, we get:

3C + 6 = 78

Subtracting 6 from both sides, we get:

3C = 72

Dividing both sides by 3, we get:

C = 24

Therefore, Corey has saved $24. We can use the first equation to find out how much Jasper has saved:

If u is indirectly proportional to t³ - 3, the value of u when t = 3 is 5.

Proportional relationships are relationships between two variables where their ratios are equivalent.

Given that;

u is indirectly proportional to t³ - 3;

u ∝ 1/( t³ - 3)

u = k/( t³ - 3)

Where k is the proportionality constant.

First, we determine the proportionality constant.

To find k, we can use the initial condition that;

24 = k / (2³- 3)

24 = k / (8 - 3)

24 = k / 5

k = 24 × 5

k = 120

Hence, the equation relating u and t is:

u = k/( t³ - 3)

Plug in k = 120

u = 120/( t³ - 3)

To find u when t = 3, we can substitute t = 3 into the equation:

u = 120/( t³ - 3)

u = 120/( 3³ - 3)

u = 120/( 27 - 3)

u = 120/24
