Given: ∠1 and ∠4 are complementary ∠4 and ∠5 are complementary
∠1 and ∠2 are complementary
∠5 and ∠6 are supplementary
m∠1 = 52°

Prove: m∠6 = 128°

make a proof chart to proving that m∠6 = 128°

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
