What is the surface area of the square pyramid represented by the net below?

A: 48 cm

B: 96 cm

C: 64 cm

D: 112 cm

The difference of two numbers is 40. find the numbers if 0.3 parts of one number is equal to 37.5% of the other one.

(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.)
