Afrog is sitting on a stump 4 feet high hops off and lands on the ground. during its leap, the frog's height h in feet is given by the equation h=-.5d^2+d+4 where d is the horizontal distance in feet from the base of the stump. what was the frog's horizontal distance from the log at its max height?

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

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.
