Use f(x)=1/2x and f-1(x)=2x to solve the problem

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

understand that i don't know the answers

will someone answer his question

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

1/3 + 1/5 = 8/15.
