If you have an average of 97.2 on your current exam and you get a 99 on your next exam, your average will increase.
- Mean in mathematics is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the total number of values.
- To find the average, sum all the values in the set. Then divide the total by the number of values.
We have the current examination mean, xold = 97.2
Now, we receive, x = 99 on the next examination, the new mean will be:
xnew = (xold + x)/N
xnew = (97.2+99)/2
xnew = 196.2/2
xnew = 98.1
The new average is 98.1
98.1 > 97.2
So if you score 99 on your next exam, your average will increase.

1 It is one because we asume that there needs to be an x. If there is no number before the x it is automatically 1x or up 1 over 1<span />
subtract them
593.7-573.36 = 20.34seconds
so c is the answer
2xy - 3x + 4xy + 8x
(Try to bring xy species together & x-type together)
2xy+4xy + 8x-3x
6xy + 5x
So, Your Answer would be 6xy + 5x
Hope this helps!
