A biologist studying trees constructed the confidence interval (0.14, 0.26) to estimate the proportion of trees in a large forest that are dead but still standing. If the sample size used to construct the interval was 50 trees, how many of them were dead but still standing? a. Anywhere from 7 to 13
b. 20
c. 3
d. 10
e. 6

step-by-step explanation:

0

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

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2
