The perimeter P of a rectangle is calculated using the formula P = 2(l + w), where l and w are the length and width of the rectangle. Rearrange the formula to make length (l) the subject.

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
