Two boats start traveling from opposite directions at the same time and meet each other after 2 hours. One boat is traveling upstream, and the other is traveling downstream. In still water, both boats have the same speed of 15 mph. The speed of the boat traveling upstream is 12 mph. Which equation represents the initial distance, d, between the boats?

The owner of the plant nursery where you were tells you to fill 350 ml bottles from a 30 l from a fertilizer

(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.)
