Let $A = \left[ \begin{array} { l l } 0.9 & 0.2 \\0.4 & 0.5\end{array} \right]$

True/False

Let $A = \left[ \begin{array} { l l } 0.9 & 0.2 \\0.4 & 0.5\end{array} \right]$ be the technology matrix, $X = \left[ \begin{array} { l } x _ { 1 } \\x _ { 2 }\end{array} \right]$ be the production vector, and $D = \left[ \begin{array} { c } 4,000 \\12,000\end{array} \right]$ be the external demand vector.

There would be 0.4 units of sector 2 needed to produce one unit of sector 2.
