You are doing a walkathon/runathon to raise money for your school. You can walk at a rate of 4 miles per hour and run at a rate of 6 miles per hour. You need to cover more than 8 miles in order to raise your part of the money. Write a linear inequality used to determine how long you must walk (w) and run (r) in order to cover more than 8 miles?

(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.)

700 miles the train takes 5 hours to a travel the distance at what unit rate is the train traveling?
