Question

Mr. Gottfried teaches two math classes. The table shows the frequencies of

different grade levels for students in his classes.

Which matrix represents the data from the table?

Answer 1

I believe it is A

Explanation:

Answer 2

A matrix that represents the data from the table include the following:
`B.\left[\begin{array}{ccc}4&5\\5&7\\21&18\end{array}\right]`

In Mathematics and Geometry, a rectangle matrix refers to a type of matrix that does not have an equal number of both rows and columns. Generally speaking, m × n matrix is typically referred to as a rectangle matrix because it is composed of m rows and n columns and vice-versa.

Based on the information provided in the table of values shown above, we can reasonably infer and logically deduce that a rectangle matrix would be formed due to the orientation of the table.

In this context, the rectangle matrix would consist of 3 rows and 2 columns. Therefore, the 3 by 2 rectangle matrix should be correctly written as depicted matrix B;

`\left[\begin{array}{ccc}4&5\\5&7\\21&18\end{array}\right]`
