In the picture below, we have triangle DEF that has been dilated from center O by scale factor r = triangle is noted by D'E'F. We also have a triangle D'EF, which is congruent to triangle DEF (i. e., A DEF =A D'EF). Describe the sequence of a dilation followed by a congruence (of one or more rigid motions) that would map triangle 1 2 The dilated d'E'T onto triangle D'EF.

(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.)
