A triangle PQR has coordinates (1, 3), (5, 1) and (3, k) respectively in an anticlockwise direction).
Find the value of k if the triangle's area is 6 units?

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

2x minus y equals 6, x plus y equals negative 3
