Answer:
- <u><em>Option A: 500 pages</em></u>
Explanation:
<u>1. Number of pages of the first 5 novels</u>
- Average = [Number of pages] / [number of novels]
- 450 pages / novel = Number of pages / 5 novels
- Number of pages = 5 novels × 450 pages / novel = 2,250 pages
<u>2. Average length of all 6 novels</u>
- Average = [Number of pages] / [number of novels]
- Number of pages of 6 novels = 2,250 pages + 750 pages = 3,000 pages
- Average = 3,000 pages / 6 novels = 500 pages / novel
Using the combination formula, it is found that photos of 9 different chairs were shown to the home owner.
The order in which the chairs are chosen is important, hence, the <em>permutation formula </em>is used to solve this question.
<h3>What is the permutation formula?</h3>
is the number of different permutations of x objects from a set of n elements, given by:

In this problem, two chairs are chosen from a set of n, and there are 72 different outcomes, hence:






Which is a quadratic function with coefficients
, hence:

Taking the positive root:

Photos of 9 different chairs were shown to the home owner.
