13.7

Step-by-step explanation:

to work this out you need to find the area of the square.

The formula for working out the area of a square is to multiply the length and the width together.

So you would multiply 8 by 8 to give the area of this square.

You would then need to work out the area of the circle using the formula:

=50.27

Then to work out the area shaded you will subtract the area of the circle from the area of the square to give you the area of the shaded region.

=13.73

rounded to 13.7

This is for question 22

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
