World production of copper, in millions of tons per year, from 1900 to 2000 is given by C = 0.5 ✕ 1.033t,
where t is the time in years since 1900.†
(a)
What production level (in millions of tons) does this model give for the year 2000? (Round your answer to two decimal places.)
million tons
(b)
If this model were extended to 2024, how could you use your knowledge of copper production in 2023 to estimate copper production in 2024?
To estimate copper production in 2024 we would multiply copper production in 202

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?
