Important Information:
A Book Has 12 Chapters.
The Mean length of the chapters is 40 pages.
Question to Answer:
How many total pages are there in the 12 chapters?
Explanation/Solution:
Let's assume that the total number of pages in the book is "x" pages.
To find the mean (average) we divide the total "x" by 12 because there are 12 chapters in the book, which would equal to 40.
=40
Multiply both sides by 12...
x = 480
Hence, The total number of pages in the 12 chapters is 480.
Solve what is in the parenthesis first. Then multiply that by 2 then divide that by 3 then multiply that by 2. know your order of operations.
1. Range is 12.
2. Median is 10.5.
3. Standard deviation is 4
