5) The projected value of an investment is modeled by the exponential function V(t) – 30,000(1.125), where V(t) is the total value
after t years. What does 1.125 represent in the function?
<))
A)
The growth factor of the investment.
B)
The initial value of the investment.
The projected value of the investment.
D)
The value of the investment after t years.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
