erica [24]

Answer:

The standard deviation of the sampling distribution of sample means would be 0.8186.

Step-by-step explanation:

We are given that

Mean of population=23.2 pounds

Standard deviation of population=6.6 pounds

n=65

We have to find the standard deviation of the sampling distribution of sample means.

We know that standard deviation of the sampling distribution of sample means

= $\frac{\sigma}{\sqrt{n}}$

Using the formula

The standard deviation of the sampling distribution of sample means

= $\frac{6.6}{\sqrt{65}}$

$=0.8186$

Hence, the standard deviation of the sampling distribution of sample means would be 0.8186.

bulgar [2K]

Answer:

20 x 20 feet

Step-by-step explanation:

First I just drew out two squares, one was the first un-cut square and the second is the cut one. Since we know that the area of the smaller square is 144, and Area is just side^2 , we know that all the sides of the smaller square are 12. Now, all we have to do is add 8 to 12 to get the original lawn. The original lawn was a 20 x 20 ft lawn.

Answer:

A cylinder with a volume of 27 $\pi$ cubic inches and a height of 3 inches

Step-by-step explanation:

Volume of a cylinder = $\pi$ r²h
(where r is the radius and h is the height)

Volume = 27 $\pi$

Height = 3

⇒ 27 $\pi$ = 3 $\pi$ r²

⇒ 9 = r²

⇒ r = √9 = 3

So height = radius
