Suppose you are playing a game with two number cubes. Each cube is numbered 1 to 6. To score a point, you must roll a double: the same number on each cube.

For each proportion find the unknown number x 1/5/8=×/15

Solve 3x-18=2y and 5x-6y=14 by elimination or substitution . show all !

(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.)
