In an experiment, a shearwater (a seabird) was taken from its nest, flown 5150 km away, and released. The bird found its way back to its nest 13.5 days after release. If we place the origin in the nest and extend the to the release point, what was the birds average velocity in (a) for the return flig

Watching TV (6.1, 7.3) Choose a young person (aged 19 to 25) at random and ask, In the past seven days, how many days did you watch television? Call the response X for short. Here is the probability distribution for X: 31 Days: 0 1 2 3 4 5 6 7 Probability: 0.04 0.03 0.06 0.08 0.09 0.08 0.05 ??? (a) W
