Using the permutation formula, it is found that there are 17,297,280 different signals consisting of 8 flags.
In this problem, the order in which the flags are visited is important, hence the <em>permutation formula</em> is used to solve this question.
<h3>What is the permutation formula?</h3>
The number of possible permutations of x elements from a set of n elements is given by:

The first flag is blue, then the remaining 7 are taken from a set of 14, hence:

There are 17,297,280 different signals consisting of 8 flags.

Hi! :)
It sounds like you need to multiply this fraction.

*16=6
So, Marge used 6 total inches of tape.
Hope this helps!
Answer:
30.8 miles per gallon
Explanation:
1.25 = 38.5
Divide both sides by 1.25
1 = 30.8
