gregori [183]

Answer:

Dependent sample: The same textbook are being compared.

Step-by-step explanation:

We are given the following in the question:

A student wants to compare textbook prices for two online bookstores.

Sample 1 from bookstore A:

$115, $43, $99, $80, $119

Sample 2 from bookstore B:

$110, $40, $99, $69, $109

Dependent and independent sample:

  • Dependent samples are paired observations for same set of items.
  • Independent samples are observations made on two different sets of items.
  • If the values in one sample affect the observations in the other sample, then the samples are dependent.
  • If the values in one sample have no effect about those of the other sample, then the samples are independent.

Thus, the given sample is dependent sample as the same textbook is being compared from two different bookstore.

What is the area of d=8 and r=4
Alex

So, for the semi circle, we need to find the area of a circle then divide it by 2.

pi times r squared

\pi 16 is the area of a circle with the radius of 4

(I'm going to use 3.14 as pi)

So 3.14 times 16 is 50.24

Divide that by 2 and we get 25.12

For the rectangle at the bottom. We know that the radius is four, so we can cut off 4ft from the height, leaving us with 8.

8 times 8 is 64.

To find the area of the whole figure, we add 64 and 25.12 together, getting 89.12

So the area is 89.12 feet squared.
