Isabelle proves that the triangles are congruent by using the parallel lines to determine a second set of angles are congruent. what statement and reason could she have used? ∠abc ≅ ∠bac; corresponding angles of parallel lines are congruent. ∠cab ≅ ∠dcb; alternate interior angles of parallel lines are congruent ∠abc ≅ ∠dcb; alternate interior angles of parallel lines are congruent ∠acd ≅ ∠abd; corresponding angles of parallel lines are congruent.

In the triangles, bc =de and ac fe.if the mzc is greater than the mze, then ab isdfelth

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
