Ricardo throws a stone off a bridge into a river below. The stone's height (in meters above the water), x seconds after Ricardo threw it, is modeled by w (x) = -5 (x 8) (x + 4) How many seconds after being thrown will the stone reach its maximum height?

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
