Answer:
![X = \left[\begin{array}{cccc}12&-24&8&16\end{array}\right]](https://tex.z-dn.net/?f=X%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D12%26-24%268%2616%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
A matrix is given by
![A = \left[\begin{array}{cccc}6&-12&4&8\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D6%26-12%264%268%5Cend%7Barray%7D%5Cright%5D)
Now, we have to find the matrix X if 
⇒ X = 2A
Now, multiplication of a constant with a matrix means multiplication with that constant with all the terms of the matrix.
So, ![X = \left[\begin{array}{cccc}6 \times 2&-12 \times 2&4 \times 2&8 \times 2\end{array}\right]](https://tex.z-dn.net/?f=X%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D6%20%5Ctimes%202%26-12%20%5Ctimes%202%264%20%5Ctimes%202%268%20%5Ctimes%202%5Cend%7Barray%7D%5Cright%5D)

Answer: The ferris wheel could accomodate 900 people in 6 hours. The rate per hour was 150 people.
Step-by-step explanation:
To start off we can find the number of people by deciding how many time slots of 30 minutes are in 6 hours. Since 30 minutes is half an hour we just do 2 times 6 which would give us 12. Since 75 people can fit in 30 minutes then we do 12 times 75 for the whole 6 hours which comes out to 900.
Once we have the number of people in 6 hours then we can find the hourly rate. To do this we just take the number of people (900) in the whole time (6 hours) and divide 6 from 900 which would give us the hourly rate of 150.
