I got 2 as an answer
Step-by-step explanation:

![{x}^{4} = 16 \\ \sqrt[4]{ {x}^{4} } = \sqrt[4]{16} \\ x = 2](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B4%7D%20%20%3D%2016%20%5C%5C%20%20%5Csqrt%5B4%5D%7B%20%7Bx%7D%5E%7B4%7D%20%7D%20%20%3D%20%20%5Csqrt%5B4%5D%7B16%7D%20%20%5C%5C%20x%20%3D%202)
Answer:
-96.875
Step-by-step explanation:
The number of possible seats is an illustration of permutation
There are 1728 possible sitting arrangements
<h3>How to determine the number of seats</h3>
From the question, we have the following highlights:
- Chris can only take 1 seat (i.e. the central seat)
- Jo can take 2 seats (i.e. the seats adjacent the central seat)
- Alex, Barb and Dave can take 3! number of seats
- Eddie, Fred, and Gareth can take 3! number of seats on the right of Chris.
- The remaining 4 adults do not have preference, then they can seat in 4! ways
So, the number of sitting arrangement is:

Evaluate the product

Hence, there are 1728 possible sitting arrangements
