A human cannonball is an act where a performer is launched through the air. The height of the performer can be modeled by h(x)=−0.004x^2+x+19, where ℎ is the height in feet and is the horizontal distance traveled in feet. The circus act is considering a flight path directly over the main tent. If the performer wants at least 5 ft of vertical height clearance, how tall can the tent be? Round your answer to the nearest foot.

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
