31 points to anyone who can me on this math! assignment: systems of equations investigation mrs. hudson has given you the task of investigating systems of equations and their graphs. you should solve each system of linear equations and then look for a commonality between each set of equations. find a pattern that can be used to solve a system by inspection.

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
