What number would you add to both sides of x2 + 7x = 4 to complete the square? a.2^2 b.7^2 c, 7^2/2 d.(7/2)^2

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

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}

10 b/c 5*2 =10
