4x2 - 6x + 7
When x= -4,4x2 - 6x +7=

What are the relative frequencies to the nearest hundredth of the columns of the two-way table?

Which shows the graph of the solution set of 3y – 2x > –18?

(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.)
