Alphonse donates a fair amount of money to various charities each year. He wants to know that his money is actually going to do the charity work, though. Suppose that 90% of the charities that he donates to are probably reputable and 10% are probably not. Also, suppose that 80% of the money that goes to the real charities ends up actually being used for the charity work, while 20% goes to administrative costs. If he donates the same amount to each charity, then what percent probably goes to actual charity work? 72| % SUBMIT ANSWER O ASK FOR HELP TURN IT IN to search 344 111 80 Y U D H. V
Bill commutes to work in the business district of Boston. He takes the train 2/5 of the time and drives 3/5 of the time (when he visits clients). If he takes the train, then he gets home by 6:30 p.m. 76% of the time; if he drives, then he gets home by 6:30 p.m. 50% of the time. If Bill gets home by 6:30 p.m., what is the probability that he drove to work? (Round your answer to three decimal places.)
The sport of Professional Bull Riders (PBR) is a world-wide phenomenon where riders mount a bull with the intention of staying on the bull for at least eight seconds as the bull spins, kicks, and twists attempting to throw, or buck, them off. If a rider does not successfully ride for eight seconds, then no points are earned. Each eight-second ride is worth up to 100 points where 50 points is for the bull's performance and 50 points is for how adept the rider is. When judging the bull, judges look at how hard a time the bull gives the rider; the harder the ride, the more points are awarded. Generally, bulls who display more power, speed, and agility are awarded more points. We will explore some data regarding the bulls from the 2019 PBR season. The dataset consists of the bull's name, average time when a rider was bucked off a bull (Avg Buckoff Time), and each bull's average score (Avg Bullscore). The first five rows of the data look like this. + Name SMOOTH OPERATOR SMOOTH WRECK…
