In her end-of-year exams, Jennie scored the following: Science 34%, English 90%, History 87%, Math 34%, and Geography 55%. What was the mean?

The mean was 60%.

Explanation:

The mean is the average of your numbers. To calculate the mean you would have to add all the numbers together. Then, you’d divide your total amount by how many numbers you had to add together. For this example, you would add 34+90+87+34+55. This gives you a total of 300. Since you had 5 initial numbers, you would divide 300 by 5. You will come up with a final number of 60 which is your mean.

I'd say the Science and Math tteachers!

seriously- add all the scores and divide by the 5 classes.

Explanation:

34+90+87+34+55= 300

300÷5= 60
