Amachine is used in a production process. from past data, it is known that 97% of the time the machine is set up correctly. furthermore, it is known that if the machine is set up correctly, it produces 95% acceptable (non-defective) items. however, when it is set up incorrectly, it produces only 40% acceptable items. a. an item from the production line is selected. what is the probability that the selected item is non-defective? b. given that the selected item is non-defective, what is the probability that the machine is set up correctly?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
