At a point 500m from the base of a water tank the angle of elevation of the top of the tank is 45o. Find the height of the tank,
Find the median of the following set of numbers: 28, 29, 39, 38, 33, 37, 26, 20, 15, 25
The table above shows the scores of a group of 40 students in a physics test.
If the mode is m and the median is n, then (m,n) is
| Score | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
| Frequency | 2 | 3 | 6 | 7 | 9 | 6 | 2 | 2 | 3 |
