The data set below shows the number of books checked out from a library during the first two weeks of the month 99,29,30,42,35,36,30,35,38,43,39,40 ,28,31 which of the following statements is true based on the data set

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
