Select the correct answer. Liam chooses an investment plan that requires him to make an initial investment of $8,000. Then he contributes equal monthly investments of $300 for the next 10 years. What function represents the amount in dollars that Liam has invested in terms of the number of months since he made the initial investment? A. Y = 8,000 − 300x B. Y = -8,000 + 300x C. Y = 8,000 + 300x D. Y = 300 − 8,000x E. Y = 300 + 8,000x

C. Y = 8,000 + 300x

Step-by-step explanation:

Given: Initial investment = $8,000

Monthly investment = $300

Let x = the number of months since he made the initial investment.

Y= the amount in dollars that Liam has invested.

Now , Amount invested = Initial investment + (Monthly investment) x ( number of months)

Y = 8000 + 300x

Hence, the required function : Y = 8000 + 300x

So, the correct option is C. Y = 8,000 + 300x

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
