PLEASE HELP ME ASAP simplify to create an equivalent expression. 5+7(8r-2) A: 56r+3 B: 56r+9 C: 8r-9 D: 56r-9

What happens to the area as the sliders are adjusted? what do you think the formula for the area of a triangle is divided by 2?

(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.)
