Aquality analyst wants to construct a control chart for determining whether three machines, all producing the same product, are in control with regard to a particular quality variable. accordingly, he sampled four units of output from each machine, with the following results: machine measurements #1 17 15 15 17 #2 16 25 18 25 #3 23 24 23 22 what are the x-bar chart three-sigma upper and lower control limits? multiple choice 24 and 16 23.16 and 16.84 23.29 and 16.71 23.5 and 16.5 22 and 18

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

The dash figure is a dilation if the original figure. find the scale factor. classify the dilation as an enlargement or a reduction

Our star pitcher, foster enlight, can throw a pitch so fast that it gets to the catcher’s mitt before it leaves foster’s fingers! if the team wins a game then the probability that foster was pitching is 0.8 but only if foster had at least one day’s rest since his last pitching assignment. if foster does not have a day off and the team still wins, the probability that foster was pitching drops by half of what it was on the previous day. if the team wins three games in succession from the toronto tachyons and foster pitched in game #2, what is the probability that he pitched in one or more of the other games? (assume that foster did not pitch on the day before the first game of this three game series.)
