Which pair of numbers are not opposites? Select one: a. 27 and |-27| b. 72 and -72 c. |7| and -7 d. 27 and -27

Solve the equation x/4 - 5= -8 -27 -12 -7 12

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

(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.)
