What is b? 3.2 = 4/5 (b-5)
I know this has already been answered, but I need a better explanation, I just does't make any sense.

Which of the following describes the symmetry of the graph of y = x3?

(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.)

What rule describes a dilation with a scale factor of 4 and the center of dilation at the origin?
