If y - 8 = 5x, what is the value of x if the value of y is -87

x=-19

Step-by-step explanation:

Plug -87 into y, and and -87-8 is -95, and divide that by 5

The answer is -19

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
