Which equation is correct? 792 × 5 = 700 × 5 + 90 × 5 + 2 792 × 5 = 700 × 5 + 90 × 5 + 2 × 5 792 × 5 = 7,000 × 5 + 900 × 5 + 20 × 5 792 × 5 = 700 + 90 × 5 + 2 × 5

Which of those sequences is a geometric sequence

Factor and solve to find roots x squared -x - 90 =0

(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.)
