Considering the given stem-and-leaf plot, the quartiles are given as follows:
- The first quartile is of 67.5.
- The second quartile, which is the median, is of 84.5.
- The third quartile is of 91.5.
<h3>What are the median and the quartiles of a data-set?</h3>
- The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
- The first quartile is the median of the first half of the data-set.
- The third quartile is the median of the second half of the data-set.
There is an even number of elements(26), hence the median is the mean of the 13th and 14th elements, which are 83 and 86, hence:
Me = (83 + 86)/2 = 84.5.
The first half has 12 elements, hence the first quartile is the mean of the 6th and 7th elements, which are 67 and 68, hence:
Q1 = (67 + 68)/2 = 67.5.
The third half also has 12 elements, starting at the second 86, hence the third quartile is the mean of the 6th and 7th elements of this half, hence:
Q3 = (91 + 92)/2 = 91.5.

Answer:
The inequality  have a dashed line
 have a dashed line
Step-by-step explanation:
we have

The solution of this inequality is the shaded area below the dashed line
The equation of the dashed line is 
The slope of the dashed line is positive
The y-intercept of the dashed line is -5 ---> point (0,-5)
The x-intercept of the dashed line is x=3 ----> point (3,0)

Answer:

Step-by-step explanation:
First we have to write down what it says in the question in as an expression. So we know that there is already 3 people on Britany's team (herself and the two friends),  that in order to participate in the league you will need at least 9 players, and that the team can have a maximum of 15 player. So....
Let "x" be the number of people who decided to join Britany and her friends
Let "y" be the total number of people on Britanie's team, then .....
3 + x = y
Now we need to remember that in order to participate in the league you will need at least 9 players, and that the team can have a maximum of 15 player. We can write that down as......

Now from this we know that the minimum value that x would need to take in order for Brittany's team to participate can be found by solving 3 + x = 9. The maximum value that x would need to take in order for Brittany's team to participate can be found by solving 3 + x = 15. And so we get.....
Minimum value:
3 + x = 9
x = 9 -3
x = 6
Maximum value:
3 + x = 15
x = 15 - 3
x = 12
Now we know that x will be equal to any integer between 6 and 12 so
