A: 5x - 2y = 10
b: 4x + 3y = 7
to solve this system of equations by addition, what could you multiply each equation by to cancel out the x-variable a) multiply a by 3 and b by 2
b) multiply a by 4 and b by 5
c) multiply a by -3 and b by 2
d) multiply a by -4 and b by 5

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.)
