A figure has a perimeter of 15 units. What will the new perimeter be after a dilation with a scale factor of 5?

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

Ineed to know the answer to this algebra question.

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if
