circle a has center of (0, 4) and a radius of 6, and circle b has a center of (−3, 5) and a radius of 24. what steps will show that circle a is similar to circle b?

translate circle a using the rule (x + 3, y − 1).
rotate circle a 180° about the center.
dilate circle a by a scale factor of 4.
reflect circle a over the line y = x.

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
