Which statements about the diagram are true? select three options.

x = 63

z = 117

x + z = 180

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

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
