You have conducted pre- and post-test measures of the effectiveness of pay raises on employee productivity, measured as net $ sales for the month. Calculate the mean differences between the two time periods (as an absolute value) for the following 5 cases, with pre and post separated by a semi-colon:

a. Employee 1: 10000; 14000

b. Employee 2: 12000; 11000

c. Employee 3: 11000, 13000

d. Employee 4: 8000; 10000

e. Employee 5: 9000; 12000

Which graph shows the solution to the system of linear inequalities? y-4t< 4 y

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.)
