Afunction has a domain of {1, 3, 5, 7} and a range of {2, 4, 6}. which set of ordered pairs represents this function? a.{(1, 2), (3, 4), (5, 6), (7, 2)} b.{(1, 2), (3, 6), (5, 4), (5, 2)} c.{(1, 2), (3, 2), (5, 2), (7, 2)} d.{(1, 4), (3, 4), (5, 6), (7, 6)}

Asequence is defined recursively using the formula f(n + 1) =f(n) - 5. which sequence could be

(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.)
