Answer: Choice C) 5 x 3
============================================================
Step-by-step explanation:
The order of a matrix is a way of describing its size. Specifically, the order is represented in the form
, where,
- m = number of rows
- n = number of columns
The rows are laid out horizontally, and the columns are vertical.
In this case, we have 5 rows and 3 columns. Therefore, the answer is 5 x 3. The order is important because a 5 x 3 matrix is different from a 3 x 5 matrix.
