The diagram shows a track composed of a rectangle with a semicircle on each end. The area of the rectangle is 3,600 square meters. What is the perimeter of the track? Use 3.14 for pi.

What is the slope of the line shown below?

One integer is 5 more than another. their product is 104. find the integers

(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.)
