Silas took 13 bags of glass to the recycling center. he still has 11 bags of plastic to take to the recycling center. which equation could be used to find x, the total number of bags of glass and plastic silas will take to the recycling center? a.) x - 13 = 11 b.) 13 - x = 11 c.) x - 11 = -13 d.) x + 13 = 11

(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.)
