The ages (years) of three government officials when they died in office were 56, 46, and 60. complete parts (a) through (d).a. assuming that 2 of the ages are randomly selected with replacement, list the different possible samples.

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

50x5=$250

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

x = 12

y = 1

for the points!
