Assume there are three machines I, 11, and Ill in a semiconductor manufacturing facility that make chips. They manufacture, respectively, 20, 30, and 50 percent of the total semiconductor chips there. Of their outputs, respectively, 5, 4, and 2 percent of the chips are defective A chip is drawn randomly from the combined output of the three machines
(1) What is the probability that this chip is defective?
(2) Given that this chip is found defective, what is the probability that it was manufactured by machine !? by machine Il? by machine II!?

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
