How can she isolate the variable? 2 Multiply both sides by-2 and reverse the inequality symbol. ) Multiply both sides by-2 and do not reverse the inequality symbol. » Divide both sides by 12 and reverse the inequality symbol. » Divide both sides by 12 and do not reverse the inequality symbol.

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

Twelve less than a number is at most 20

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30
