Dorothy and allen each cut out a rhombus from a piece of cardboard. the side lengths of dorothy's rhombus are three times longer than the side lengths of allen's rhombus. if the area of allen's rhombus is 5 square inches, what is the area of dorothy's rhombus? i picked 30 square inches, a) 15 square inches b) 30 square inches c) 45 square inches d) 75 square inches e) 125 square inches

(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.)
