Answer:
C (20,5)
Step-by-step explanation:
The committees should contain 5 persons each
The number of people are 20
Apply combination concept
where
²⁰₅C = 20! /[ {20-5}!*5! ]
=20! / 15!*5!
=15504 ------The number of 5 person committees that could be formed from a group of 20 people.
Answer:
5: 3
Step-by-step explanation:
20:12
Divide each side by 4
20/4:12/4
5: 3
Answer:
i'm not sure if this all correct
Step-by-step explanation:
part A you start at 8 from the first participant then you take away one from the last one. you add up all the numbers up to get the answer. 8+7+6+5+4+3+2+1=36.
part B the first part is 1x1x1x1x1x1x1x1=1. the second part is 8x7x6x5x4x3x2x1= 40,320. the third part is 1/40320
Answer : The measurement of a central angle is, ![140^o](https://tex.z-dn.net/?f=140%5Eo)
Step-by-step explanation :
Formula used for angle subtended by an arc is:
![s=\frac{\pi r\theta}{180}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B%5Cpi%20r%5Ctheta%7D%7B180%7D)
where,
s = arc length = ![\frac{7}{3}\pi m](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D%5Cpi%20m)
r = radius = ![\frac{diameter}{2}=\frac{6m}{2}=3m](https://tex.z-dn.net/?f=%5Cfrac%7Bdiameter%7D%7B2%7D%3D%5Cfrac%7B6m%7D%7B2%7D%3D3m)
Now put all the given values in the above formula, we get:
![s=\frac{\pi r\theta}{180}](https://tex.z-dn.net/?f=s%3D%5Cfrac%7B%5Cpi%20r%5Ctheta%7D%7B180%7D)
![\frac{7}{3}\pi=\frac{\pi \times (3)\times \theta}{180}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B3%7D%5Cpi%3D%5Cfrac%7B%5Cpi%20%5Ctimes%20%283%29%5Ctimes%20%5Ctheta%7D%7B180%7D)
![\theta =140^o](https://tex.z-dn.net/?f=%5Ctheta%20%3D140%5Eo)
Thus, the measurement of a central angle is, ![140^o](https://tex.z-dn.net/?f=140%5Eo)
