There are about 4200 college presidents in the United States, and they have annual incomes with a distribution that is skewed instead of being normal. Many different samples of 40 college presidents are randomly selected, and the mean annual income is computed for each sample. What is the approximate shape of the sample means?
Final answer:
The distribution of sample means for college presidents' incomes, based on many different samples of size 40, will approximate a normal distribution due to the Central Limit Theorem.
Explanation:
The question regarding the distribution of sample means for college presidents' incomes pertains to a concept in statistics known as the Central Limit Theorem. When dealing with a population whose distribution is skewed, the distribution of sample means tends to become approximately normal if the sample size is large enough, which is usually considered to be over 30. As multiple samples of size 40 are taken in this case, the distribution of the sample means for the college presidents' annual incomes should approximate a normal distribution.

A line has a slope of -1/2 and a y-intercept of –2.
what is the x-intercept of the line?
y = (slope)x + (y-intercept)
y = -1/2x - 2
x-intercepts occur when y = 0
0 = -1/2x - 2
2 = -1/2x
x = -4
Thus, the x-intercept is at (-4,0)

a rectangular flower garden has area of 32 square feet. if the width of the garden is 4 feet less than the length, what is the perimeter, in feet, of the garden?
To find the perimeter of the rectangular flower garden, we first need to find its dimensions. Once we have the length and width, we can calculate the perimeter by using the formula: P = 2(length + width). Therefore, the perimeter of the garden is 4x - 8 feet.
Explanation:To find the perimeter of the rectangular flower garden, we first need to find its dimensions. Let's use x to represent the length of the garden.
According to the problem, the width of the garden is 4 feet less than the length, so the width would be x - 4.
The area of the garden is 32 square feet, so we can set up the equation: x * (x - 4) = 32.
We can solve this equation by factoring or by using the quadratic formula to find the length.
Once we have the length and width, we can calculate the perimeter by using the formula: P = 2(length + width).
Substituting the values, we get P = 2(x + x - 4), which simplifies to P = 4x - 8.
Therefore, the perimeter of the garden is 4x - 8 feet.

how many times more respondents chose silver than red round to the nearest tenth if necessary silver 0.2 red 0.09
Answer: 2.2
Step-by-step explanation:
Given : Proportion of choosing silver = 0.2 =0.20.
Proportion of choosing red= 0.09
Clearly, 0.20> 0.09
Now, the number of times more respondents chose silver than red will be :-
[tex] n=\dfrac{0.20}{0.09}\\\\=\dfrac{20}{9}\\\\=2.22222\approx2.2\ \text{ Rounded to the nearest tenth}[/tex]
Hence, 2.2 times the respondents chose silver than red.

What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.
Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Let's say 0.6 is 10 times as much as x
Then,
0.6 = 10x
x = 0.6/10 = 0.06
Hence "0.6 is 10 times as much as 0.06".

Which function has an inverse that is also a function? a {(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)} b {(–1, 2), (0, 4), (1, 5), (5, 4), (7, 2)} c {(–1, –2), (0, 4), (1, 3), (5, 14), (7, 4)} d {(–1, 4), (0, 4), (1, 2), (5, 3), (7, 1)}
Answer:
Which function has an inverse that is also a function? a {(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2)} b {(–1, 2), (0, 4), (1, 5), (5, 4), (7, 2)} c {(–1, –2), (0, 4), (1, 3), (5, 14), (7, 4)} d {(–1, 4), (0, 4), (1, 2), (5, 3), (7, 1)}
Step-by-step explanation:
It is called the inverse or reciprocal function of f to another function f − 1 that fulfills that:
If f (a) = b, then f − 1 (b) = a.
The inverse of a function when it exists is unique, so that neither "X" nor "Y" can be repeated.
If we analyze the possibilities, in the case of b, c, and d, the value 4 of the "Y" is repeated twice; in the case of a, that does not happen, therefore the answer is: a {(–1, 3), (0, 4), (1, 14), (5, 6), (7, 2) }

Find the critical numbers of the function.
g(y) = y − 3 / y2 − 3y + 9
To find the critical numbers of the function g(y) = (y - 3) / (y^2 - 3y + 9), we need to find the values of y for which the derivative of g(y) is equal to zero or does not exist. By following the steps above, we find that the function has no critical numbers.
Explanation:To find the critical numbers of the function g(y) = (y - 3) / (y^2 - 3y + 9), we need to find the values of y for which the derivative of g(y) is equal to zero or does not exist.
First, find the derivative of g(y) using the quotient rule: g'(y) = (1*(y^2 - 3y + 9) - (y - 3)*(2y - 3)) / (y^2 - 3y + 9)^2. Simplify g'(y) by expanding and collecting like terms to get g'(y) = 6y^2 - 24y + 24 / (y^2 - 3y + 9)^2. To find the critical numbers, set g'(y) equal to zero and solve for y. In this case, there are no real solutions. Next, check for values of y where g'(y) does not exist. In this case, there are no such values.
Therefore, the function g(y) = (y - 3) / (y^2 - 3y + 9) has no critical numbers.

It takes 40 min for a bus to travel the 36 miles from Framingham to Worcester. A car traveling from Worcester to Framingham moves 1.5 times as fast as the bus. If the car and the bus start moving towards each other simultaneously, after how many minutes will they meet?
The velocity of the bus is:
velocity (bus) = 36 miles / 40 min
velocity (bus) = 0.9 miles / min
Since the car is 1.5 times faster, so the velocity of the car is:
velocity (car) = 1.5 * 0.9 miles / min
velocity (car) = 1.35 miles / min
At the meeting point, the sum of the distance is equal to 36 miles. Therefore:
1.35 t + 0.9 t = 36
2.25 t = 36
t = 16 min
So they will meet after 16 minutes.
