video streaming company a charges a one-time $40 membership fee and $2 per video stream. video streaming company b charges a one-time $20 membership fee and $4 per video stream.

Company A:

c = 40 + 2s

Company B:

c = 20 + 4s

Equal costs => 40 + 2s = 20 +4s => 4s - 2s = 40 - 20 => 2s = 20 => s = 20/2

=> s = 10

And c = 20 + 4s = 20 + 4(10) = 20 + 40 = 60

Step-by-step explanation:

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
