We're going to be using combination since this question is asking how many different combinations of 10 people can be selected from a set of 23.
We would only use permutation if the order of the people in the committee mattered, which it seems it doesn't.
Formula for combination:

Where
represents the number of objects/people in the set and
represents the number of objects/people being chosen from the set
There are 23 people in the set and 10 people being chosen from the set


Usually I would prefer solving such fractions by hand instead of a calculator, but factorials can result in large numbers and there is too much multiplication. Using a calculator, we get

Thus, there are 1,144,066 different 10 person committees that can be selected from a pool of 23 people. Let me know if you need any clarifications, thanks!

Answer:
1) Given
2) Isosceles triangle's 2 sides are equal. Vertex angle is M. So, ML = MN
3) Given
4) T divided LN into to equal parts.
5) Common
6) SSS
Answer: 960
Step-by-step explanation: all you have to do to find the volume is 10*8*12, which would be 960, so the cubic volume is 960.
The <em><u>correct answer</u></em> is:
HL
Explanation:
These will both be right triangles, as angle Q and angle Q' are both 90 degrees.
Since Q and Q' are the right angles, this means that RS and R'S' are the hypotenuses of the two right triangles.
Since Q'R'S' was created by translating QRS, a corresponding leg of both triangles will be congruent; this gives us hypotenuse-leg, or HL.
