Step-by-step explanation:
There are 5005 different groups
<h3>How to determine the number of groups?</h3>
The given parameters are:
Players, n = 15
Selected, r = 6
The number of groups is then calculated as:
![Group = ^{n}C_r](https://tex.z-dn.net/?f=Group%20%3D%20%5E%7Bn%7DC_r)
This gives
![Group = ^{15}C_6](https://tex.z-dn.net/?f=Group%20%3D%20%5E%7B15%7DC_6)
Apply the combination formula
![Group = \frac{15!}{9!6!}](https://tex.z-dn.net/?f=Group%20%3D%20%5Cfrac%7B15%21%7D%7B9%216%21%7D)
Evaluate the expression
Group = 5005
Hence, there are 5005 different groups

<u><em>Answer:</em></u>
Jenna did 16 regular haircuts
Jenna did 8 haircuts with coloring
<u><em>Explanation:</em></u>
Assume that the number of regular haircuts is x and the number of haircuts plus coloring is y
<u>We are given that:</u>
<u>1- Jenna did a total of 24 clients, this means that:</u>
x + y = 24
This can be rewritten as:
x = 24 - y ...............> equation I
<u>2- regular haircuts cost $25, haircuts plus coloring cost $42 and she earned a total of $736. This means that:</u>
25x + 42y = 736 ..........> equation II
<u>Substitute with equation I in equation II and solve for y as follows:</u>
25x + 42y = 736
25(24-y) + 42y = 736
600 - 25y + 42y = 736
17y = 136
y = 8
<u>Substitute with y in equation I to get x as follows:</u>
x = 24 - y
x = 24 - 8
x = 16
<u>Based on the above:</u>
Jenna did 16 regular haircuts
Jenna did 8 haircuts with coloring
Hope this helps :)
