1. Mean is the number you get when you add all these numbers and then divide by the number of numbers. So, (31 + 28 + 30 + 31 + 30) / 5 = 150 / 5 = 30
2. The median is the middle number in the list of numbers, so, the answer is 30 as well.
3. Mode is the number that appears most often, so here it is 30 and 31 because they both appear 2 times.
4. Range is the difference between the largest and smallest number, so 31 - 28 = 3.
The set of real numbers is all numbers that can be shown on a number line. It also includes rational numbers, which are numbers that can be written as a ratio of two integers, and irrational numbers, which cannot be written as a the ratio of two integers.
By the chain rule,
We also have
,
, and
, so at this point we get
Note: 2*2 means 2 times 2
find the factors since
4/8=1/2 because 1/2 times 4/4=4/8
194=2*97
120=2*2*2*3*5
the common number is 2 so divide both by 2
97/60 is the simplest form
in improper fraction form it is
97-60=37
1 37/60
