Answer :
To create a single matrix that shows the total number of outdoors ans indoors by age, we can add the two matrices:
[tex]T=\begin{bmatrix}{17} & 35{} \\ {}8 & 26{}\end{bmatrix}+\begin{bmatrix}{}9 & 20{} \\ {2}4 & 23{}\end{bmatrix}[/tex]Then we add:
[tex]T=\begin{bmatrix}{26} & {55} \\ {32} & {49}\end{bmatrix}[/tex]b) The value of:
[tex]T_{2,2}[/tex]Is the value of the second column in the secfond row. In this case, T_22 = 49
c) To substract the men's matrix from the women's matrix:
[tex]\begin{bmatrix}{9} & {20} \\ {24} & {23}\end{bmatrix}-\begin{bmatrix}{17} & {35} \\ {8} & {26}\end{bmatrix}=\begin{bmatrix}{-8} & {-15} \\ {16} & {-3}\end{bmatrix}=D[/tex]d) The value of
[tex]d_{2,1}=16[/tex]The first number is the row number, and the second number is the column number
