Answer:
Example of matrices such hat 
Step-by-step explanation:
We have two give example of 2×2 matrices such that AB = AC BUT B ≠ C.
Example:
![A =\left[\begin{array}{ccc}1&0\\0&0\end{array}\right]\\\\B = \left[\begin{array}{ccc}1&1\\1&2\end{array}\right], C = \left[\begin{array}{ccc}1&1\\1&3\end{array}\right]](https://tex.z-dn.net/?f=A%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%5C%5C0%260%5Cend%7Barray%7D%5Cright%5D%5C%5C%5C%5CB%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%261%5C%5C1%262%5Cend%7Barray%7D%5Cright%5D%2C%20C%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%261%5C%5C1%263%5Cend%7Barray%7D%5Cright%5D)
Solving:
![AB = \left[\begin{array}{ccc}1+0&1+0\\0+0&0+0\end{array}\right] = \left[\begin{array}{ccc}1&1\\0&0\end{array}\right]](https://tex.z-dn.net/?f=AB%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%2B0%261%2B0%5C%5C0%2B0%260%2B0%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%261%5C%5C0%260%5Cend%7Barray%7D%5Cright%5D)
![AC = \left[\begin{array}{ccc}1+0&1+0\\0+0&0+0\end{array}\right] = \left[\begin{array}{ccc}1&1\\0&0\end{array}\right]](https://tex.z-dn.net/?f=AC%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%2B0%261%2B0%5C%5C0%2B0%260%2B0%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%261%5C%5C0%260%5Cend%7Barray%7D%5Cright%5D)
Hence,

Answer: d) Easton
<u>Step-by-step explanation:</u>
Let's evaluate Round 1 (blue) for each bowler:
Jimmy --> the lowest score is 0.5 SD below the mean
Claudia --> the lowest score was the mean
Easton --> the lowest score is 0.75 SD below the mean
Cynthia --> the lowest score was the mean
The person that had the worst game is: Easton
Answer:
Yes
Step-by-step explanation:
Well because 125/10 would be a function, and it is linear then it should be proportional. In other words if you increase one number the other increases at the same rate. Hope I Helped :)
