Answer is 11/25 games lost which is 44%.
Step by step. 25 games minus 14 they won equals 11 games lost out of 25.
11 out of 25 = 11/25.
11/25 as a % - 11 divided by 25 = .44 which is 44%.
Check your work, 44% of 25 games = 11 games lost.

Using the mean concept, it is found that we will need 15 more points to bring up his average up to 90%.
The mean of a data-set is the <u>sum of all observations divided by the number of observations</u>.
In this problem:
- In the first 5 observations, total of 21 out of 25 points, hence the mean for these observations is
. - In the next n observations, mean of 1.
Hence, the mean is:

We want the mean to be of 0.9, thus:





3 more testes are need, each worth 5 points, hence, 15 more points are needed to bring up his average up to 90%.
