Step-by-step explanation:

For the first one, 3.25/2.5=1.3. For the second one, 5.98/4.6=1.3. For the third one, 6.76/5.2=1.3 Since the ratio is constant for all three (1.3), x and y are proportional. Hope this helps!

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

all it means is function 3
