There is a bag with only red marbles and blue marbles. The probability of randomly choosing a red marble is 7 12 . There are 72 marbles in total in the bag and each is equally likely to be chosen. Work out how many red marbles there must be.

(01.04 mc) an ice sculpture is melting because of heat. assuming its height changes bynegative 5 over 32m every hour, what will be the change in height after 4 hours?

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.
