Answer:
290.6 backpacks per year
Step-by-step explanation:
The average of 5 numbers is 1/5 of their sum:
average = (278 +310 +320 +242 +303)/5 = 290.6
The average number of backpacks given out in the last 5 years is 290.6, about 291.
Well you would first add 5/13 and 2/13, so 7/13. Then you would subtract 7 from 13. So your answer would be 6/13. Hope that helped!
187/9= 20.7
20 remainder 7
You do Y2-Y1 Divided by X2-X1
It is 44. Can't argue about that
