Step-by-step explanation:
Given
See attachment for complete question
Solving (a); Number of students represented.
To do this, we simply calculate the length of each bar and then sum them up.
So, we have:
[tex]Jan = 16[/tex]
[tex]Feb = 10[/tex]
[tex]Mar = 18[/tex]
[tex]Apr = 15[/tex]
[tex]May = 5[/tex]
[tex]Jun = 11[/tex]
So, the total is;
[tex]Total = Jan + Feb + Mar + Apr + May + Jun[/tex]
[tex]Total = 16 + 10 + 18 + 15 + 5 +11[/tex]
[tex]Total = 75[/tex]
Solving (b): Prediction of February students out of a total of 750.
To do this, we use:
[tex]Students = \frac{Month}{Total} * 750[/tex]
For February, we have:
[tex]Students = \frac{Feb}{Total} * 750[/tex]
[tex]Students = \frac{10}{75} * 750[/tex]
[tex]Students = \frac{10 * 750}{75}[/tex]
[tex]Students = \frac{7500}{75}[/tex]
[tex]Students = 100[/tex]
