There is 150% increase in the number of volunteers.
Step-by-step explanation:
Given,
Old number of volunteers = 20
New number of volunteers = 50
Change = New value - Old value
Change = 50 - 20 = +30
The positive sign indicates the increase.
Percent increase =

First point given: (5,4)
Y = -1/4x + b
4 = -1/4(5) + b
4 = -5/4 + b
b = 2.75
Equation: y = -1/4x + 2.75
Find three points
(5,4), (9,5), (1,3)
Plot these and draw a line
Hey!
I assume you're talking about percentage. What was the percentage increase from 86 books to 150.
Using the formula to find percentage increase, we will solve this:
{(86 - 150) / 86} × 100 = 74.42
So, the percent increase from 86 books to 150 is 74.42%
% increase = (final - initial) / initial * 100
= (131 - 92) / 92 * 100
= 39/92 * 100
= 3900/92
= 42.39%
In short, Your Answer would be 42.39%
Hope this helps!
The first thing you have to do is order them least to greatest. Once that is done you need to find your first, second and third quartile. to find them is simple. You have to find the median of the data set. Then from the number on either side of the median you have to find the median of this data sets. The median of the entire set is your second quartile then the medium to the left is your first and the median to your right is the third quartile. For the number line you need to make numbers that are appropriate for the number range. Then place your least number, the first, second, and third quartile, then place your greatest number. then draw a line up from the median and the first and third quartile and create a box.
