Describe three different ways to change the numbers of black and red chips on the original board, but leave the value of the board

unchanged.

Which ahows the graph of the solution set of 6x+4y< 12

Which expression will have the same sum as 3_8 + 1/4?

(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.)
