A rectangular prism is completely packed with 54 cubes of edge length 1/2 inch, without any gap or overlap. Which of these best describes the volume of this rectangular program?

Which statement about perfect cubes is true

It says factor each expression 49x-28?

(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.)
