2.multiple-choice questions each have
four
possible answers (a, b, c, d),
one of which is correct. assume that you guess the answers to three such questions.
a. use the multiplication rule to find
p(cww),
where c denotes a correct answer and w denotes a wrong answer.
p(cww)equals=
(type an exact answer.)
in a study of helicopter usage and patient survival, among the 48,693 patients transported by helicopter,
280 of them left the treatment center against medical advice, and the other 48,413 did not leave against medical advice. if 60 of the subjects transported by helicopter are randomly selected without replacement, what is the probability that none of them left the treatment center against medical advice?

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
