A ball is thrown from a height of 32 meters with an initial downward velocity of 2/ms.

The ball's height h (in meters) after t seconds is given by the following.

h=−32−2t-5t^2

How long after the ball is thrown does it hit the ground? Round your answer(s) to the nearest hundredth.

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
