If cos θ = 7/25, use the pythagorean identity to find tan θ.
7/24
24/25
24/7
25/24
explain why

The hawaiian alphabet has 12 letters. how many permutations are posible for each number of letters?

Ineed with math stuff it involves graphs

(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.)
