Answer: A
The samples are not independent of each other.
Explanation: Khan Answer
They are testing the same sample of students both times. Results from the first test would likely give us information about the results from the second test.
The F-test is used to determine whether the variances of two populations are equal (Snedecor and Cochran, 1983). It is possible for this test to have one or two tails. The two-tailed version compares the variances' equality with the alternative. Thus, option A is correct.
What nutritionist use formula for standard deviation?Rejecting a null hypothesis that is actually true in the population results in a type I error (false-positive); failing to reject a null hypothesis that is actually untrue.
To calculate how much your values (data points) normally deviate from the mean value, use the standard deviation formula. In other words, the standard deviation tells you how much your data vary.
Therefore, The samples are not mutually exclusive. After giving the kids nutritious snacks at school for three months, they retest the kids.

These two right cylinders have the same height, 25 centimeters. The radius of the smaller cylinder is 5 centimeters and the radius of the larger cylinder is 3 times greater than that of the smaller cylinder. What is the ratio of the volume of the larger cylinder to the volume of the smaller cylinder? A. 6:1 B. 12:1 C. 9:1 D. 25:1
9514 1404 393
Answer:
C. 9:1
Explanation:
The volume is proportional to the square of the radius. When the ratio of radii is 3 : 1, the ratio of volumes is 3^2 : 1^2 = 9 : 1.
Answer:C! 9:1

The ATT Building (IE Batman Building) in Nashville is 614 feet tall. A model of the building is 60 inches tall. What is the ratio of the height of the model to the height of the actual ATT Building?
Answer:
Ratio of height of model to height of the actual Building = 5 : 614
Explanation:
Given:
ATT Building height = 614 feet tall
Model of building = 60 inches tall
Find:
Ratio of height of model to height of the actual Building
Computation:
ATT Building height = 614 feet tall = 614 x 12 = 7,368 inch
Ratio of height of model to height of the actual Building = Model of building / ATT Building height
Ratio of height of model to height of the actual Building = 60 / 7,368
Ratio of height of model to height of the actual Building = 5 : 614
The Ratio of the height of the model the actual ATT Building is 5 / 614
Equation
An equation is an expression used to show the relationship between two or more numbers and variables.
12 inches = 1 feet.
Height of model = 60 inches = 60 in. * 1 ft. per 12 in. = 5 ft.
Ratio of the height of the model the actual ATT Building = 5 / 614

x=5
10(5)-5
50-5=45
hope it helps :)
brainlist pls
Answer:
45
Explanation:
First we find the value of x, i.e.
2x – 1 = 9,
=> 2x = 9 + 1
=> 2x = 10
[tex] = > x = \frac{10}{2} [/tex]
=> x = 5
As we have got the value of x so now,
10x – 5
= (10 × 5) - 5
= 50 - 5
= 45 (Ans)

On a certain hot summer's day, 185 people people used the public swimming pool.The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $335.50.How many children and how many adults swam at the public pool that day?
Answer: 139 adults and 46 children. Did you not get this? I'm in 8th grade!!!!!!!
Explanation: a=adults, c=children
Rewrite equations:
a+c=185
2a+1.25c=335.5
Step: Solve a+c=185for a:
a+c=185
a+c+−c=185+−c (Add -c to both sides)
a=−c+185
Step: Substitute −c+185 for 'a' in 2a+1.25c=335.5:
2a+1.25c=335.5
2(−c+185)+1.25c=335.5
−0.75c+370=335.5 (Simplify both sides of the equation)
−0.75c+370+−370=335.5+−370 (Add -370 to both sides)
−0.75c=−34.5
−0.75c
−0.75
=
−34.5
−0.75
(Divide both sides by -0.75)
c=46
Step: Substitute 46 for 'c' in 'a' =−c+185:
a=−c+185
a=−46+185
a=139(Simplify both sides of the equation)
Answer:
a(adults)=139 and c(children)=46
