the ratio of males to females in a class is 2 : 3 . the career preferences of the students in the class are represented in a circle graph . if the area of the graph allocated to each career preference is proportional to the number of students who have that career preference , how many degrees of the circle should be used to represent a career that is preferred by one - half of the males and three - fourths of the females in the class ?
"1 / 2 * 2 / 5 + 3 / 4 * 3 / 5 = 4 / 20 + 9 / 20 = 13 / 20 the number of degrees is 13 / 20 * 360 = 234 degrees the answer is c ."
divide(multiply(2, const_360), add(2, 3))
