Given Circle S, what is the area of the shaded sector, to the nearest
square centimeter?

51

Step-by-step explanation:

area = pi x r^2

so

3.14 x 25

around 76

so

2/3 of 76

is

51

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
