Answer:

a) To find the percentage of years with an annual rainfall of less than 44 inches, we need to find the area under the normal curve to the left of 44. Using a standard normal distribution table or a calculator, we find the z-score corresponding to 44 inches:

z = (44 - 40.9) / 5.3 = 0.585

The area to the left of z = 0.585 is approximately 0.7202. Therefore, about 72.0% of years will have an annual rainfall of less than 44 inches.

b) To find the percentage of years with an annual rainfall of more than 38 inches, we need to find the area under the normal curve to the right of 38. Using a standard normal distribution table or a calculator, we find the z-score corresponding to 38 inches:

z = (38 - 40.9) / 5.3 = -0.717

The area to the right of z = -0.717 is approximately 0.4713. Therefore, about 47.1% of years will have an annual rainfall of more than 38 inches.

c) To find the percentage of years with an annual rainfall between 37 inches and 43 inches, we need to find the area under the normal curve between the corresponding z-scores:

z1 = (37 - 40.9) / 5.3 = -0.736

z2 = (43 - 40.9) / 5.3 = 0.396

Using a standard normal distribution table or a calculator, we find the area between z = -0.736 and z = 0.396 is approximately 0.6181. Therefore, about 61.8% of years will have an annual rainfall between 37 inches and 43 inches.

Step-by-step explanation:

Step-by-step explanation:

a) To find the percentage of years with an annual rainfall of less than 44 inches, we need to find the area under the normal distribution curve to the left of 44 inches.

Using a standard normal distribution table or calculator, we can find the z-score:

z = (44 - 40.9) / 5.3 = 0.585

The area to the left of this z-score is approximately 0.72, or 72%.

Therefore, approximately 72% of years will have an annual rainfall of less than 44 inches.

b) To find the percentage of years with an annual rainfall of more than 38 inches, we need to find the area under the normal distribution curve to the right of 38 inches.

Using a standard normal distribution table or calculator, we can find the z-score:

z = (38 - 40.9) / 5.3 = -0.736

The area to the right of this z-score is approximately 0.77, or 77%.

Therefore, approximately 77% of years will have an annual rainfall of more than 38 inches.

c) To find the percentage of years with an annual rainfall between 37 inches and 43 inches, we need to find the area under the normal distribution curve between the z-scores for 37 inches and 43 inches.

Using a standard normal distribution table or calculator, we can find the z-scores:

z1 = (37 - 40.9) / 5.3 = -0.736

z2 = (43 - 40.9) / 5.3 = 0.394

The area between these z-scores is approximately 0.53, or 53%.

Therefore, approximately 53% of years will have an annual rainfall between 37 inches and 43 inches.

The radian measure of an angle is directly proportional to the length of the arc intercepted by that angle on the unit circle.

Proportional is a mathematical concept that describes the relationship between two or more values that have a constant ratio. It is commonly used to describe the relationship between two or more variables, such as the size of an object in relation to another or the amount of a certain item in relation to the total amount. In proportionality, the ratio of the amounts remains consistent, no matter what the size of the values.

This means that as the angle increases, so does the length of the arc. This is because the length of an arc is determined by the angle measure of the central angle created by the arc, and the radian measure of an angle is the ratio of the arc length to the radius of the circle. Therefore, if the angle measure increases, so does the arc length.

Let's use algebra to solve this problem.

Let x be one of the integers, and y be the other integer.

From the problem, we know that:

x = 4y + 17 (one integer is 17 more than 4 times the other)

xy = -15 (the product of the two integers is -15)

We can use substitution to solve for one of the variables. From the first equation, we can write:

y = (x - 17)/4

Substituting this expression for y into the second equation gives:

x(x - 17)/4 = -15

Multiplying both sides by 4 and expanding gives:

x^2 - 17x = -60

Rearranging gives:

x^2 - 17x + 60 = 0

This is a quadratic equation that can be factored as:

(x - 5)(x - 12) = 0

So the solutions are:

x = 5, y = (-12/4) = -3

x = 12, y = (-5/4) = -1.25

Since the problem states that the integers are both integers, the only valid solution is:

x = 5, y = -3

Therefore, the two integers are 5 and -3.

In the above prompt involving a trajectory calculation, the correct option is: "The kick is not successful. The ball is approximately 5 feet too low." (Option A)

x component of trajectory =   73 cos 34   f/s  

   Now how long will it take to travel 49 yards (= 147 feet) ?

         147 / (73 cos 34) = 2.43 seconds

Initial y component of trajectory = 73 sin 34 f/s = 40.82 f/s  

    but this velocity is acted upon by gravity

       y = y0 + vot - 1/2 a t^2      

                         y0 = 0        

Now we need to know the y value at 2.43 seconds to see if it will clear the uprights.

y = 40.82 (2.43)  - 1/2 (32.174)(2.43)2  

= 4.2 Feet      
Thus, it is correct to state that the "The kick is not successful. The ball is approximately 5 feet too low."

What is arithmetic?

Arithmetic is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots.

Here, we have

Given: A hiker is climbing a local peak. After 1.5 hours of hiking, he is at an altitude of 220 feet. After 4 hours, he is at an altitude of 410 feet.

We have to find the hiker's altitude after 4.5 hours.

We have height as a function of time:

x = time, y = height

Our two points are (1.5, 220), (4, 410), and (4.5,x)

(4-1.5) = (410-220)

2.5 = 190

1 = 190/2.5

1 hours = 76 feet

0.5 hours = 38 feet

4.5 hours = 410 + 38 feet = 448 feet

1. The equilibrium quantity = 60, the equilibrium price = 300

2. If the government imposes the tax of 24, the quantity supplies would fall to 56, and the price would rise to 308

At equilibrium we have P = Q

that is price is equal to quantity. Such that we would have:

420-2q = 60+ 4q

take the like terms

420 - 60 = 4q + 2q

360 = 6q

q = 360 / 6

q = 60

The equilibrium quantity = 60 then equilibrium price =

Complete question:

Answer:

the probability that a randomly chosen refill will fit correctly is 0.9780 (rounded to three decimal places).

Step-by-step explanation:

We can use the standard normal distribution to solve this problem. We first need to calculate the z-scores for the given diameters.

a) To find the probability that a randomly chosen refill will be too large, we need to find the probability of getting a diameter greater than 0.520 mm.

z-score = (0.520 - 0.5) / 0.007 = 2.857

Using a standard normal table or calculator, we find that the probability of getting a z-score of 2.857 or greater is 0.0021.

Therefore, the probability that a randomly chosen refill will be too large is 0.0021 (rounded to three decimal places).

b) To find the probability that a randomly chosen refill will be too small, we need to find the probability of getting a diameter less than 0.485 mm.

z-score = (0.485 - 0.5) / 0.007 = -2.143

Using a standard normal table or calculator, we find that the probability of getting a z-score of -2.143 or less is 0.0164.

Therefore, the probability that a randomly chosen refill will be too small is 0.0164 (rounded to three decimal places).

c) To find the probability that a randomly chosen refill will fit correctly, we need to find the probability of getting a diameter between 0.485 mm and 0.520 mm.

First, we find the z-scores for each diameter:

z-score for 0.485 mm = (0.485 - 0.5) / 0.007 = -2.143

z-score for 0.520 mm = (0.520 - 0.5) / 0.007 = 2.857

Using a standard normal table or calculator, we find that the probability of getting a z-score between -2.143 and 2.857 is 0.9780.

Therefore, the probability that a randomly chosen refill will fit correctly is 0.9780 (rounded to three decimal places).

The largest pοssible median fοr the five-number set (x, 2x, 3, 2, 5) is 8.5 (if x is οdd) οr 5.5 (if x is even)

The median is the middle value in a set οf numbers arranged in οrder. It is the value that separates the higher half frοm the lοwer half.

Tο find the largest pοssible median fοr the five-number set (x, 2x, 3, 2, 5), we need tο cοnsider the different cases when x is an integer.

First, let's arrange the numbers in οrder:

{2, 3, 2x, 5, x}

Tο find the median, we need tο determine the middle number in the set. If the set has an οdd number οf elements, the median is the middle number. If the set has an even number οf elements, the median is the average οf the twο middle numbers.

Case 1: x is even

If x is even, then 2x is even and x < 2x. Therefοre, the middle numbers are 2x and 3, and the median is (2x + 3) / 2.

Case 2: x is οdd

If x is οdd, then 2x is even and 2 < 2x. Therefοre, the middle numbers are 2 and 2x, and the median is (2 + 2x) / 2.

Tο find the largest pοssible median, we need tο maximize (2x + 3) / 2 οr (2 + 2x) / 2, depending οn whether x is even οr οdd. This οccurs when x is the largest pοssible integer, which is:

x = 4 (if x is even)

x = 7 (if x is οdd)

Therefοre, the largest pοssible median fοr the five-number set (x, 2x, 3, 2, 5) is:

(2x + 3) / 2 = (2(7) + 3) / 2 = 8.5 (if x is οdd)
