Samples of size n= 240 are randomly selected from the population of numbers (O through 20)
produced by a random-number generator, and the variance is found for each sample. What is
the distribution of the sample variances?
normal (approximately)
skewed to the right
skewed to the left
not enough information provided
Answers
Based on the information provided, it is not possible to identify the distribution of the sample variances, and the correct answer is "not enough information provided.".
What is Sample Variance?The distribution of data points in a particular data collection around the mean is measured by sample variance. The population is the sum of all observations of a group. When the number of observations rises, calculating the population variance gets complicated.
It is not possible to determine the distribution of the sample variances based on the information provided. The distribution of the sample variances depends on the distribution of the population from which the samples are drawn. Without knowing the distribution of the population, it is not possible to determine the distribution of the sample variances.
Therefore, the correct answer is "not enough information provided."

h - 9 = 7
explain how you found h
Answers
Answer:
h=16
Step-by-step explanation:
h-9=7
h=9+7
h=16
I hope this helps.
Answer:
H=16
Step-by-step explanation:
H is a variable representing an unknown number. What you would do for this equation is:
Start with a number like 10, and plug it into the eqation where h is, 10-9=7
We know that is a false statement. So since 10-9=1, all you do is think what plus one equals 7. 1+6=7 so take 6 and add it to 10. Replace the variable h with 16. 16-9=7
That is correct, so H=16.

evaluate 8.1v +7.5w when v = 7 and w = 8
Answers
Answer:
116.7
Step-by-step explanation:
8.1v + 7.5 w
since v= 7 and w= 8
8.1(7) + 7.5(8)
= 56.7 + 60
= 116.7
7.5 times 8 equals 60
When you add these two numbers together, you get 116.7. This is your answer.

In his garden tim plants the seed 5 1/2 in. below the ground. After one month the tomato plant has grown a total 8 3/4 of in. How many inches is the plant above the ground ?
Answers
Answer:
6 1/4 in
Step-by-step explanation:
Tim plants tomato seeds in the garden 3 1/4 inches i.e. 13/4 inches below the ground level.
After one month the tomato plant has grown a total of 9 1/2 inches i.e. 19/2 inches.
So, it first grew up to ground level then it grew above ground level.
Therefore, the height of the plant above the ground level will be
[(19/2)-(13/4)] =(38-13)/4 =25/4 inches i.e. 6 1/4 inches.
6 1/4 inches

Step-by-step explanation:
So a triangle adds to 180 degrees, 96+48= 144
180-144=36
36 is the answer for the angle to the right of x
to find x you must find its coterminal angle (I think is the word, They have to add to 180)
so 36 + 144 is 180

Answers
Answer:
[tex]1. = {x}^{12} [/tex]

1. 3 * 4 = 12. Or x + x + x + x + x + x + x + x + x + x + x + x = x^12
Explaination: when there are parentheses followed by a multiplier, you must multiply everything within the parentheses. Since the multiplier in this case is an exponent, simply multiply the 2 exponents together and move the base to the other aide of the equal sign.
2. 4 * 2 = 8.
Explaination: Same as above. Since x and y are unlike terms, you cant simplify this equation any further.

All 3 do not equal to each other. Proving that Juwon's statement is wrong.
Answer:
The first two are equivalent but different than the third.
Step-by-step explanation:
[tex]8n+6 = 2(4n+3) => 6=6\\8n+6 = 14n => 6n = 6 => n = 1\\\\[/tex]
The first two are identical by factoring 2 out of the first one, or distributing 2 in the second one.
The equality of the first and third equations, suggests that it is only true for n = 1.
To prove it wrong, find a number that shows the inequality:
[tex]n = 2\\8n+6 = 2(4n+3) = 22\\14n = 28\\\\22 \neq 28[/tex]
