Suppose that 20% of the applicants to an engineering school are women. an admissions committee reviews applications in groups of 100. find the probability that the number of women in the next group is:

(a) less than or equal to 28
pr=
(b) between 27 and 42 inclusively
pr=
(c) greater than 28
pr=
(d) less than 8
pr=
(e) exactly 40
pr=
(f) greater than 46
pr=

School has 204 sixth grade students. if the sixth grade is 30% of the total school, how many students are in the middle school?

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14

Given abc find the values of x and y. in your final answer, include all of your calculations.
