Writing About Polynomials 1) Imagine you have to teach someone how to simplify polynomials and they
have NO EXPERIENCE with the topic. Briefly explain how to identify and
combine similar terms using the following equation:

2x + 9x2 - 6x + x3

(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.)
