Katelynn and Travis go on a trip. When they start out, their odometer reads 34,118 miles. If they drive 320 miles the first day, what will the reading on their odometer be? Part B: Katelynn and Travis forgot to write down their mileage on the second day, but after the third day their odometer read 34,963 miles. What was the average number of miles they drove during the second and third days?

Part C: At the end of the third day, Katelynn and Travis reached their destination. They spent 4 days at their destination and then they drove home. If it only took them 2 days to drive home, what was their average number of miles driven each day, assuming they followed the same route home with no side trips?

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
