We need 14 feet of casing to put along all four sides of a rectangular window. If the length of the window is 4 feet , find the width .

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^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.)

Solve for x and select the correct answer
