The dimensions of the matrix are 3 by 3 i.e. 3 x 3, and the indicated element a₂₃ is -7
<h3>The dimension of the matrix?</h3>
From the figure in the question, we have the following highlights:
- The matrix has 3 rows
- The matrix has 3 columns
The dimensions of a matrix are represented by: Row by column
Hence, the dimensions of the matrix are 3 by 3
<h3>The indicated element</h3>
This is given as:
a₂₃
This means that the element is located at the second row and the third column.
The element at this position is -7
Hence, the indicated element is -7

Step-by-step explanation:
The data constitutes nominal scale of measurement when the observations can be classified into groups. For example, students are classified into groups on the basis of eye color. The numerical values can also be use in nominal scale for grouping. For example, the students can be categorize into 1,2 and 3 if they have brown, black and green eye color. But they have no numerical significance. Thus, data obtained from a nominal scale can be either numeric or non-numeric.

Had to solve in the comment section because I couldn't find the answer button before. It Just appeared Lol.
You can still check the solution in the first guy's comment section
d=vt will represent the Motion of Both persons
for Karen
d=59t
for Ricardo
d=65t
They're both 279miles away from each other
Meaning
Dk + Dr = 279
59t + 65t = 279
124t=279
t=279/124
t= 2.25hrs.
You can change to seconds if thats how the answer waa presented.
