in a class of 40 students, 80% are business majors. of the 24 students who passed the midterm exam, 75% are business majors. What percertange of students in the class who are not business majors passed the examination
80% of 40 = 32
So -- 8 students are not business majors.
75% of 24 = 18
So 6 non-business majors passed the test.
What percentage is 6 out of 8?
I love Pre Alegbra but i don't get it
If you post a couple of the problems you don't get, we'll be glad to help you.
Out of 39 students in a finite math class, 25 are male, 23 are business majors, 24 are first-year students, 15 are male business students, 18 are male first-year students, 16 are first-year students who are business majors, and 12 are male first-year business majors.
To find the percentage of students in the class who are not business majors and passed the examination, we need to calculate the number of non-business majors who passed the exam and then divide it by the total number of students who are not business majors.
First, let's find the number of business majors in the class. Since 80% of the class are business majors, we can calculate it as:
Number of business majors = 80% of 40 students
Number of business majors = 0.8 * 40
Number of business majors = 32 students
Next, let's find the number of business majors who passed the exam. We are given that 75% of the 24 students who passed the exam are business majors, so we can calculate it as:
Number of business majors who passed the exam = 75% of 24 students
Number of business majors who passed the exam = 0.75 * 24
Number of business majors who passed the exam = 18 students
Now, we can find the number of students who are not business majors. We subtract the number of business majors from the total number of students:
Number of students who are not business majors = Total number of students - Number of business majors
Number of students who are not business majors = 40 - 32
Number of students who are not business majors = 8 students
Finally, let's find the percentage of students who are not business majors and passed the exam:
Percentage of students who are not business majors and passed the exam = (Number of non-business majors who passed the exam / Number of students who are not business majors) * 100
Percentage of students who are not business majors and passed the exam = (24 - 18) / 8 * 100
Percentage of students who are not business majors and passed the exam = 6 / 8 * 100
Percentage of students who are not business majors and passed the exam = 75%
Therefore, 75% of the students in the class who are not business majors passed the examination.
