Answer:
8 seats
Step-by-step explanation:
n = 8 ---booths
r = 1 --- hostess
Order is required
Important Order? We solve using permutation.
nPr = n!/(n - r)!
So we have:
8p1 = 8!/(8 - 1)!
IF we do the math correctly, we get this:
8p1 = 8/7!
Finally let's expand to come up with the solution.
8p1 = 8 x 7/7
8p1 = 8
So the answer is 8!
I hope this helps! Have a good day (PLS GIVE BRAINLIEST)
There are 8 types of different arrangements possible for the hostess to seat customers at the waiter’s booths if order is important.
What is Permutation and Combination ?
The various ways in which objects from a set may be selected, generally without replacement, to form subsets. This selection of subsets is called a permutation when the order of selection is a factor, a combination when order is not a factor.
Total number of booths = 8
To determine we will use the generalized expression
How many ways can you arrange 'r' from a set of 'n' if the order matters
P(n,r) = n! / (n-r)!
P(8,1) = 8!/ (8-1)!
= 8!/7!
= 8
So there are 8 types of different arrangements possible for the hostess to seat customers at the waiter’s booths if order is important.
