Atire company hopes to adopt a new tread pattern for its tires if the pattern allows a car traveling at 60 miles per hour to come to a complete stop within an average of 125 feet after the brakes are applied. let denote the relevant population mean distance. the distances (in feet) for 5 stops on a test track are: 129; 128; 123; 128; 135: should the company adopt the new tread pattern? using a confidence interval as evidence, what would you recommend to the company on whether the tire performs as they hope? explain how you dealt with the outlier and why you made the recommendation you did.

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
