4.) A dog and a cat are both running towards a squirrel. The dog is 45 meters to the left of the squirrel and the cat is 33 meters to the right of the squirrel. Let the squirrels position
be represented by 0.
a.) Draw a diagram representing the situation
b.) If the dog is running to the right at 5 meters per second, how long will it take her to
reach the squirrel?
c.) If the cat is running to the left at 4 meters per second, how long will it take her to
reach the squirrel?
d.) If they each run for 20 seconds, describe the final position of the dog and cat.

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
