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

Here we go ~
According to given figure,
![\qquad \sf \dashrightarrow \:x + 68 = 174](https://tex.z-dn.net/?f=%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3Ax%20%2B%2068%20%3D%20174)
![\qquad \sf \dashrightarrow \:x = 174 - 68](https://tex.z-dn.net/?f=%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3Ax%20%3D%20174%20-%2068)
![\qquad \sf \dashrightarrow \:x = 106 \degree](https://tex.z-dn.net/?f=%5Cqquad%20%5Csf%20%20%5Cdashrightarrow%20%5C%3Ax%20%3D%20106%20%5Cdegree)
Question 5
FD = 63 • 2 or 126°. The reason for this is the fact that 63° is an inscribed angle.
DE is a straight line. A straight line measures 180°.
The measure of a circle is 360°.
FE = 360° - 180° - 126°
FE = 54°.
Remember: FE is a minor arc.
Understand?
Done!
Prime numbers are number that can't be divided except it is it's self and 1. For example, 3,5,7,11,13,17, 19, 23, 29, 31, 37...... All of those numbers can only be divided with itself and 1.
3 = 3x1
7 = 7x1
23= 23 x 1
