You plant an 10-inch-tall tomato plant that grows 6 inches taller each week. On the same day, you plant a 16-inch-tall tomato plant that grows 4 inches taller each week. Graph a system of equations that represents the heights y (in inches) of the plants after a weeks. Use the
graph to solve the system.

(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.)
