X2y - 2xy - 24y = y(x2 - 2x - 24) what is the completely factored form of x2y – 2xy – 24y? (xy + 4)(x – 6) xy(x + 4)(x – 6) y(x + 4)(x – 6) y(x + 4)(xy – 6)

we are given

now, we can factor out right side term

now, we can plug back

and we get

so,

.............Answer

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
