Use substitution to solve each system of equations. if the system does not have exactly one solution, state whether it has no solution or infinitely many solutions.
3x - 2y = 11
x - y/2 = 4

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
