Given:
The frequency distribution table.
To find:
The mean average score on a test.
Solution:
The frequency distribution table is

x a xa
y b yb
z c zc
Sum a+b+c xa+yb+zc
Now, the mean average score on the test is


Therefore, the mean average score on the test is
.
Given Kruger National Park in Skukuza coordinate : (-24.98,31.58).
Nelson Mandela Musuem in Mpumalanga coordinate : (-29.82,31.58).
We need to find exactly in between given coordinates.
We know, mid - point formula :


.
.
Therefore, will be meeting at (-27.4, 31.58).
