mean=the average of the numbers calculated. median=the number in the middle. mode=the numbers that appear most often
1) u would have to find the lcd of both. And that is 60 so it would be 25/60 +36/60 = 61/60 = 1 1/60
2) do the same thing as in number 1. Find the LCD it is 18. So 14/18 - 9/18 = 5/18
For both problems, we can use the section formula.
1) 
2) 
The value is x= -5/4
<h3>What is LCD?</h3>
The least common denominator is the smallest number of all the common multiples of the denominators when 2 or more fractions are given.
Given:
1/x = 1/5+ 5/4x
1/x = 4x + 25 / 20x
20= 4x +25
4x= -5
x= -5/4

The correct answers are:
Exact volume =

in^3
Approximate volume = V = 33.51 in^3
Explanation:The volume of the sphere is:

Since r = 2 in
Hence

in^3
(exact)
V = 33.51 in^3 (approximate)
