Answer:
![n^2+6n+1](https://tex.z-dn.net/?f=n%5E2%2B6n%2B1)
Step-by-step explanation:
AB would be (n) * (2n + 6). We need to distribute the n, so we multiply the n by each term within the parentheses and add those products together:
AB = ![n(2n+6)=2n^2+6n](https://tex.z-dn.net/?f=n%282n%2B6%29%3D2n%5E2%2B6n)
C is just
, and we subtract this from
:
![2n^2+6n-(n^2-1)=2n^2+6n-n^2+1=n^2+6n+1](https://tex.z-dn.net/?f=2n%5E2%2B6n-%28n%5E2-1%29%3D2n%5E2%2B6n-n%5E2%2B1%3Dn%5E2%2B6n%2B1)
Thus, the answer is
.

Answer:
3.5
Step-by-step explanation:
The interquartile range is the difference between the third and first quartile
IQR = Q3 - Q1
From the dot plot given :
The data, X could be culled :
X = 43, 44, 44, 44, 45, 45, 47, 48, 48
n = 9
Q3 = 3/4(n + 1)th term
Q3 = 3/4(10) = 7.5th term = (47 + 48) / 2 = 47.5
Q1 = 1/4(n + 1)th term
Q1 = 1/4(10) = 2.5th term = (44 + 44) / 2 = 44
Q3 - Q1 = 47.5 - 44 = 3.5
