What is a correct first step in solving the inequality –4(3 – 5x)≥ –6x + 9? –12 – 20x ≤ –6x + 9 –12 – 20x ≥ –6x + 9 –12 + 20x ≤ –6x + 9 –12 + 20x ≥ –6x + 9

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
