At hockey practice, coach Taylor sets aside 20% of the total time for players to warm up. The rest of the hockey practice is spent on a game play. Coach Taylor wants to know practice time if he has the players warm up for 15 minutes.

Which of the following quartic functions has x = –1 and x = –2 as its only two real zeroes?

The difference of two numbers is 40. find the numbers if 0.3 parts of one number is equal to 37.5% of the other one.

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.)
