Problema Solution
A sample of 80 high school seniors, 45% of which are female, were surveyed as to whether or not they are employed outside of school. 25% of the boys surveyed said they are not employed. How many boys are employed?
Answer provided by our tutors
45% of 80 students are female thus the rest are male
the total number of male students is (1 - 0.45)*80 = 44
25% of 44 are not employes the rest are employed
the number of employed male students is (1 - 0.25)*44 = 33
