Answer: The second graph
In all but the 3 graphs, the data is perfectly symmetrical. This means that the mean and the median would be the same.
However, in the second graph the data is skewed to the right. This means that the mean would also be skewed to the right due to the larger scores there. Using the median in this case would give a clearer picture of the data.
Answer:
see explanation
Step-by-step explanation:
let x be the amount Kweku gets then Kofi gets 3x , so
x + 3x = 4800
4x = 4800 ( divide both sides by 4 )
x = 1200
that is
Kweku gets $1200
Kofi gets 3 × $1200 = $3600
