Stacy has three collector cards. She receives two more cards each week that she volunteers at a school center. Let X equal The number of weeks. Let y equal the number of collector cards. Which equation represents the amount of cards Stacy has

answer:

The equation is   y = 3 + 2x

She already has Three cards.

Receives Two cards per week.

Number of weeks is 'x'

total number of collector's cards is  'y'

framing in equation form we get; y = 3 + 2x

The equation representing the total number of collector's card Stacy has in 'x' week is y = 3 + 2x

b is the final answer! : )

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
