2100/1 or 4200/2, could be either
All you have to do is
1) order data from lest to greatest
2) find 2 middle number
3) add both numbers
4) put fraction and then put 2 under the bottom
(example)
27,33,38,41,42,52,60,64,68,72
^ ^ 42+52=94 divide by 2= 94/2
AVERAGE
Mean: 49.7 Median:47
I hope this helps. X is equal to 4 and -9
The top one is the answer
68 minus 19 is 49
So the answer is there are 49 more children in the school then on the playground.
