What is the sum of the measures of the angles of a 25-gon

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x

What is the 17th term in the arithmetic sequence in which a6 is 101 and a9 is 83

(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.)
