What is the rate of change of y with respect to x?

Rate of change is ~ slope (m) of the line connecting the given point coordinates.

that is ;

Therefore, the Rate of change is ~

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
