Answer:
36.6 or 36.61
Step-by-step explanation:
the first thing you want to do is add all your numbers together.
57+28+19+19+26+54+88+65+13+10+18+50+29
this would equal 476
the second thing you do is divide your total by the amount of numbers in your equation:
476/13
which would equal:
36.6153846
Lastly, you round to the tenth place, if the number in the second place after the decimal is under 5, the number before stays the same(if its above 5 you would round up). Since the second number after the decimal is under 5 it stays the same
your answer would be 36.6 or 36.61.
I hope this helped! sorry if i messed up its been a while.
