The matrix expression that represents the transformation is:
Option: C
![4\cdot \left[\begin{array}{ccc}2&9\\-5&1\\1&-4\end{array}\right]](https://tex.z-dn.net/?f=4%5Ccdot%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%269%5C%5C-5%261%5C%5C1%26-4%5Cend%7Barray%7D%5Cright%5D)
<h2>
Step-by-step explanation:</h2>
We are given a vertices of a triangle as:
(2, 9), (-5, 1), and (1,- 4)
This means that in the matrix representation these vertices could be represented as:
![\left[\begin{array}{ccc}2&9\\-5&1\\1&-4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%269%5C%5C-5%261%5C%5C1%26-4%5Cend%7Barray%7D%5Cright%5D)
Now, when these vertices are dilated by a scale factor of 4, the change in vertices are:
Each of the vertices are multiplied by 4.
i.e. each of the entry in the matrix is multiplied by 4.
or we can take common 4 from the matrix to obtain the transformed vertices in the form as:
![4\cdot \left[\begin{array}{ccc}2&9\\-5&1\\1&-4\end{array}\right]](https://tex.z-dn.net/?f=4%5Ccdot%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%269%5C%5C-5%261%5C%5C1%26-4%5Cend%7Barray%7D%5Cright%5D)

Are you looking for where they cross ? if so its (-1,2)
Answer: The probability that all 8 people are right handed is about 27.25%.
If the chance a person is left handed, the chance a person is right handed is 85%.
Now, we just need to find the chance that this 85% event happens 8 times in a row.
Simply, multiply it by itself 8 times.
(0.85)^8 = 0.2725
There is a 27.25% chance all 8 people are right handed.
