Answer:
18
Step-by-step explanation:
We can create a ratio of the amount of students who picked green over the total amount of students.
9 students picked the green pattern, and a total of 50 students were surveyed. This means the ratio is [tex]\frac{9}{50}[/tex].
To turn [tex]\frac{9}{50}[/tex] into a percentage, we must divide it's numerator by it's denominator and multiply by 100.
[tex]8\div50=0.18\\\\0.18\cdot100=18[/tex]
So the green bar's height will be 18.
Hope this helped!
