Johan found that the equation –2|8 – x| – 6 = –12 had two possible solutions: x = 5 and x = –11. which of these statements explains whether his solutions are correct?
a.) he is correct because both solutions satisfy the equation.
b.) he is not correct because he made a sign error.
c.) he is not correct because there are no solutions.
d.) he is not correct because there is only one solution: 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
