Given: m || cb prove: m∠abc + m∠bac + m∠acb = 180° which statement justifies that angle xab is congruent to angle abc? corresponding angles of parallel lines cut by a transversal are congruent. vertical angles are congruent. same-side interior angles of parallel lines cut by a transversal are supplementary. alternate interior angles of parallel lines cut by a transversal are congruent.

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
