Select the points that will coincide with vertices of the triangle after it is dilated by a scale factor of 2 with the center of dilation at the origin.

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

multiple all that

step-by-step explanation:
