Answer:
the answer is A
Step-by-step explanation:
To find the interquartile range, you will list the data that is presented in the stem and leaf plot.
Find the median of the data (30.5)
Find the median of the lower half and the median of the upper half.
Subtract these two values.
The data are <u>20</u>, 25, 30, 30, 31, 40, 41, <u>49</u>.
27.5 40.5
40.5-27.5 = 13
The interquartile range is 13.
I think it’s c I had this question lol
1. Given a group of n people. There are C(n, r) ways of forming groups of r out of n.
2. Where C(n, r)=
![\frac{n!}{r!(n-r)!}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D%20)
3. For example, given {Andy, John, Julia}. We want to pick 2 people to give a gift: we can pick {(Andy, John), (Andy, Julia), (John, Julia)}, so there are 3 ways. So we can list and count.
4. Or we could do this with the formula C(3, 2)=
![\frac{3!}{2!(1)!}= \frac{3*2*1}{2*1}=3](https://tex.z-dn.net/?f=%5Cfrac%7B3%21%7D%7B2%21%281%29%21%7D%3D%20%5Cfrac%7B3%2A2%2A1%7D%7B2%2A1%7D%3D3%20%20)
5. C(8, 6)=
![\frac{8!}{2!6!}= \frac{8*7*6!}{2*6!}= \frac{8*7}{2}= 4*7=28](https://tex.z-dn.net/?f=%5Cfrac%7B8%21%7D%7B2%216%21%7D%3D%20%5Cfrac%7B8%2A7%2A6%21%7D%7B2%2A6%21%7D%3D%20%5Cfrac%7B8%2A7%7D%7B2%7D%3D%204%2A7%3D28)
So there are C(8,6)=28 ways of chosing 6 out of 8 people to form the subcommittees. <span />
