Isabella is solving the equation 4x^2=13x−3 with the quadratic formula. which values could she use for a, b, and c? a. a = 4, b = −13, c = 3 b. a = 4, b = 3, c = −13 c. a = 4, b = 13, c = −3 d. a = 4, b = −3, c = 13

The accompanying table shows the numbers of male and female students in a particular country who received bachelor's degrees in business in a recent year. complete parts (a) and (b) below. business degrees nonbusiness degrees total male 189131 634650 823781 female 169539 885329 1054868 total 358670 1519979 1878649 (a) find the probability that a randomly selected student is male, given that the student received a business degree. the probability that a randomly selected student is male, given that the student received a business degree, is nothing. (round to three decimal places as needed.) (b) find the probability that a randomly selected student received a business degree, given that the student is female. the probability that a randomly selected student received a business degree, given that the student is female, is nothing. (round to three decimal places as needed.)
