I have a question of the mod snog, why do you keep deleting my questions?

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

What should be done to both sides of the equation in order to solve -5m = -40? a) multiply by -5. b) divide by -5. c) multiply by -40. d) divide by -40.

Choose the right classification of 5x + 3x^4 - 7x^3 + 10 by number terms and he degree 1. third degree polynomial 2. fourth degree polynomial 3. sixth degree polynomial 4. first degree binomial
