Amit solved the equation StartFraction 5 over 12 EndFraction = Negative StartFraction x over 420 EndFraction for x using the steps shown below. What was Amit’s error?

StartFraction 5 over 12 EndFraction = Negative StartFraction x over 420 EndFraction. StartFraction 5 over 12 EndFraction (420) = Negative StartFraction x over 420 EndFraction (420). X = 175.

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

Which is true regarding the graphed function f(x)?
