Answer:
18564 ways
Step-by-step explanation:
The number of committees is equal to the number of combinations of 6 members that we can form out of 18 person :
then
This can be done in
ways.
![C^{6}_{18}=\frac{18!}{6!\left(18-6 \right)! } = 18564](https://tex.z-dn.net/?f=C%5E%7B6%7D_%7B18%7D%3D%5Cfrac%7B18%21%7D%7B6%21%5Cleft%2818-6%20%5Cright%29%21%20%20%7D%20%3D%2018564)

Step-by-step explanation:
Answer:
17.1
Step-by-step explanation:
1. Find the Mean
(25+40+35+25+40+60+75)/7 = 42.9
2.For each number, subtract the Mean and square the result.
(25-42.86)^2=319
(40-42.86)^2=8.2
(35-42.86)^2=61.8
(25-42.86)^2=319
(40-42.86)^2=8.2
(60-42.86)^2=293.8
(75-42.86)^2=1033
3. Find the Mean of those squared differences.
(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9
4.Take the square root of that and this is what you want.
square root of 291.9 = 17.1
