What are the standard equation for a circle center with (1,-3) and the point (2,1)

What are the sotions to the quadratic equation 9x^2=4

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

Evaluate the expression. (9 + 5)(3 + 2)0
