Nobody has figured this what are the possible rational zeros of f(x) = 2x3 − 15x2 + 9x + 22? ± 1, ± 2 ± 1, ± 2, ± 11, ± 22 ± 1, ± 1 over 2, ± 2, ± 11 over 2, ± 11, ± 22 ± 1, ± 1 over 2, ± 1 over 11, ± 1 over 22, ± 2, ± 2 over 11

What is the measure of angle x? answer

(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.)
