Using the percentile concept, it is found that 10 students scored lower than he did.
<h3>What is the meaning of the percentile of a measure?</h3>
When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.
In this problem, he scored on the 20th percentile, that is, higher than 20% of the 50 students. Then:
0.2 x 50 = 10.
10 students scored lower than he did.

Question 1)
Volume of Tank A = Sum of volume of its two parts.
So,
Volume of Tank A = 24 + 96 = 120 cubic feet
Question 2)
Volume of Tank B and Tank A is the same. So, Volume of Tank B = 120 cubic feet
One section of Tank B = 45 cubic feet
So, volume of other section of tank B = 120 - 45 = 75 cubic feet
Divide 360 by the number of sides or angles that the polygon has
Answer:
The percentage change from July to November is 67.27 %
Step-by-step explanation:
Given as :
The number of tourists at the beach per weekend in the month of July = 
= 55,000
The number of tourists at the beach per weekend in the month of November = 
= 18,000
Let the percentage change from July to November = A %
Or, % decrease change = 
× 100
So , A % = ![\dfrac{\tetxtrm [tex]x_2](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctetxtrm%20%5Btex%5Dx_2)
- \textrm }{\textrm }[/tex] × 100
or, A % = 
× 100
Or, A % = 
× 100
Or, A = 67.27 %
So percentage change between two months = 67.27 %
Hence The percentage change from July to November is 67.27 % Answer
