11. Rihanna works in a coffee shop approximately eighteen miles from her apartment. She bikes
every day from her apartment to the coffee shop and then back to her apartment in the
evening. On her way to work, she always stops halfway through to meet her best friend at a
park. If the distance from Rihanna's apartment to the park is (2x + 5) miles and the trip form the
park to the coffee shop is (25 – 8x) miles long, then what is the value of x?

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.)
