Practice Question 1: Michael is moving to a smaller house and needs to get rid of his old toys to save room. He currently has 800 toys and needs some time to decide which ones to keep. A the end each week, he is going to give half of his toys to a Local Children's Hospital.

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?

(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.)

Written as a simplified polynomial in standard form, what is the result when (2x+8)^2(2x+8) 2 is subtracted from 8x^2-38x 2 −3?
