The number of kilograms, y, of a radioactive element that remains after t hours can be modeled by the equation y=0.23(0.91)t. What is the rate of decrease of this radioactive element?

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
