-2+2=0 because on the number line -2 is two spots from 0 then when u add a positive 2 it equals 0.
What is the interquartile Range for the following data set? {5,6,7,3,9,8,3,1,6,7,7}

To find the interquartile range of the data, you get both quartile one (1) and two (2) and subtract the larger number from the lower number.
Q3 - Q1 = Interquartile range
Your answer, in turn, would be...
4
Answer:
There are
rows in the theater.
Step-by-step explanation:
Given terms.
Seats in order
will form an Arithmetic progression.
As the common difference
,same for three consecutive terms so this an AP.
Now accordingly we can put the AP terms.
Total number of seats 
Seats in the first row 
Seats in the last row 
Summation of
terms in AP
![S_n={\frac{n}{2}[2a+(n-1)d]}](https://tex.z-dn.net/?f=S_n%3D%7B%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D%7D)
OR
![S_n=\frac{n}{2}[a+l]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5Ba%2Bl%5D)
Using the second equation.
![S_n=\frac{n}{2}[a+l]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5Ba%2Bl%5D)
![1560=\frac{n}{2}[23+81]](https://tex.z-dn.net/?f=1560%3D%5Cfrac%7Bn%7D%7B2%7D%5B23%2B81%5D)

So the number of rows (n) in the theater 
Well 1 is in the ones place so its 1
.848 is 848 thousandths so it would be 1
The Critical points and the Trig Functions are not really that different than the methods you always use for finding those critical points for any other types of functions and the Critical points are points that the derivative is set as a 0 or it can be undefined.<span />
