For what value of c is the relation a fiction ?
{(2,8),(12,8),(c,4),(-1,8,),(0,3)}

Find the height of a square pyramid that has the volume of 32 ft.³ and a base lengthof 4 feet

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).

(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.)
