Hi! Jared is knitting a blanket at a constant rate. He finds that the length of the blanket in inches, l, can be modeled by the equation l=5t+1, where t represents the number of hours spent knitting. What are the independent and dependent variables in this situation? Drag and drop the answer into the box to match the variable type.

Thank you!

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?
