Answer: median
Step-by-step explanation: In this situation the mean is widely preferred as the best measure of central tendency because it is the measure that includes all the values in the data set for its calculation
Answer:
![\sqrt[n]{a} =a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20%20%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
Explanation:
Roots of real numbers can be represented by <em>radicals</em> or by<em> exponents. </em>
First, I present some examples to show how exponents and radicals are related, and then generalize.

![\sqrt[3]{8}=(8)^{\frac{1}{3}}=(2^3)^{\frac{1}{3}}=(2)^{\frac{3}{3}}=2^1=2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%3D%288%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%3D%282%5E3%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D%3D%282%29%5E%7B%5Cfrac%7B3%7D%7B3%7D%7D%3D2%5E1%3D2)
When you write 5² = 25, then 5 is the square root of 25.
And in general, if n is a positive integer and
, then
is the nth root of x.
Also, if n even (and positive) and
is positive, then
is the positive nth root of 
Thus,
![\sqrt[n]{a} =a^{\frac{1}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20%20%3Da%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D)
If you counted up until they were 100 kilometers apart it would look like this:
Mr. A - 100, 200, 300, 400, 500
Ms. R - 80, 160, 240, 320, 400
They were 100 kilometers apart in 5 hours.
The weight of an object is determined by gravitational force, so the more it weighs, the more gravitational force it has
this is not to be mistaken with mass, which has nothing to do with weight. <span>An </span>objects<span> mass is determined by the number of unit masses that make it up.</span>
You make it a improper fraction and it would be 21/8 and then divide 21 by 8 and you get 2.625
