Abicycle tire is pumped to a pressure of 120 psi (pounds per square inch). while riding his bike, daniel ran over a small nail, and the tire has a small hole in it. air is leaking and the tire is losing pressure at a rate of 12 psi per minute. if you graphed the pressure of the tire as the output, compared to the number of minutes as the input, which of the following statements about the graph would not be true? a. the graph would be a line. b. the graph would rise from left to right. c. the graph would be only in the first quadrant. d. the more time has passed, the lower the psi would be.

Find the roots of the equation below. x^2 - 6 + 9 = 0

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
