The area of a sail is 40 1/2 square feet. the base and the height of the sail are equal. what is the height of the sail (in feet)?

Height of the sail is 9 feet.

Step-by-step explanation:

Since sail is in the shape of a triangle and the formula of a triangle is

Area = (1/2)×Base×Height

Area of the sail has been given in the question and we have to calculate the height of the sail.

40.5 = (1/2)× Height× Height ( since base = height)

40.5×2 = height² = 81

height = √81 = 9 feet.

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
