Which problem has no real solution?

3(2x + 7) = 6(x + 4) – 3

3(6x – 5) = 3(6x – 5) + x

8(x – 3) + 14 = 2(4x + 5)

13x – 7 = 12(x – 1) + x + 5

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
