Find the determinancof the matrix Q.

stepan [7]

Using a Laplace expansion along the first column, we have

$\det Q=2\det\begin{bmatrix}2&1\\-1&6\end{bmatrix}+3\det\begin{bmatrix}3&4\\-1&6\end{bmatrix}+5\det\begin{bmatrix}3&4\\2&1\end{bmatrix}$

The determinant of a 2x2 matrix is trivial,

$\det\begin{bmatrix}a&b\\c&d\end{bmatrix}=ad-bc$

So we have

$\det Q=2\cdot13+3\cdot22+5\cdot(-5)=67$

<h3>Answer: B) Brookfield</h3>

For each location, divide the number of hamsters over the number of gerbils.

Brookfield would have a ratio of 28/10 = 2.8

Belmont would have the ratio of 27/13 = 2.077 approximately

We see that Brookfield has the higher ratio.
