The function f(x) represents the time it takes an airplane to travel east. the function g(x) represents the time it takes an airplane to travel west. given f(x) = 4x + 13 and g(x) = 10x − 2, solve for (f + g)(x) to determine the total roundtrip time.
a.(f + g)(x) = 14x + 15
b. (f + g)(x) = 14x + 11
c .(f + g)(x) = 6x + 11
d. (f + g)(x) = 6x + 15

(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.)
