Sebastian writes the recursive formula f(x+1) = 3*f(x) to represent a geometric sequence whose second term is 15. Which of the following represents the sequence?

Name the most appropriate metric unit for each measurement like a length of an carrot

What is the value of x when x + 7 = 21?

(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.)
