If the sides of a triangle have the following lengths, find a range of possible values for x. 1. PQ = 7x + 13, QR = 10x - 2. PR = x + 27

(please explain how to do it)

Given abcd ac=38 and ae=3x+4 find the value of x

What can you determine about the solutions of this system

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
