Answer:
I gotchu! The answer is 80.
Explanation:
To find the mean, you need to add up all the scores and divide it by how many scores there are. In this case, there are 5 scores, so we can first add them all up.
70+75+80+85+90=400
Now, since there are 5 scores, you need to divide 400 by 5.
400/5=80
The mean would be 80.
Hope that helped!
Have a great day!
