Suppose ‾PR ≅ ‾ST and ∠P ≅ ∠S. Ron wants to prove △PQR ≅ △STU by SAS. He says that all he needs to do is show ‾RQ ≅ ‾SU. Will this work? Explain.

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e. g. 98.7654). x f(x) 0 1 2 3

Explain how you divide powers with like bases. discuss why the bases have to be the same. how are these rules similar to the rules for multiplying powers with like bases.
