Sat question
can someone explain to me how i would go about solving a problem like this ?

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

Suppose the equation of a line is 2x − 4y = − 8. which coordinate pair represents the y-intercept?

Angle x and y are complementary. angle x is supplementary to a 128° angle. what are the measures of angle x and angle y? write an equation to solve for x first. then find the measure of angle y
