Let LaTeX: A= X^{T} X = \begin{bmatrix}5 &3 \\4 & 2\end{bmatrix}A = X T X = [ 5 3 4 2 ]. What is the correct representation of LaTeX: A^{-1} A βˆ’ 1? Select the most appropriate option. Group of answer choices LaTeX: A^{-1} = \frac{1}{det(A)} \begin{bmatrix}5 &3 \\4 & 2\end{bmatrix}A βˆ’ 1 = 1 d e t ( A ) [ 5 3 4 2 ] LaTeX: A^{-1} = \frac{1}{5 + 2 + 4 + 3} \begin{bmatrix}2 &-3 \\-4 & 5\end{bmatrix}A βˆ’ 1 = 1 5 + 2 + 4 + 3 [ 2 βˆ’ 3 βˆ’ 4 5 ] LaTeX: A^{-1} = \frac{1}{5*2-4*3} \begin{bmatrix}2 &-3 \\-4 & 5\end{bmatrix}A βˆ’ 1 = 1 5 βˆ— 2 βˆ’ 4 βˆ— 3 [ 2 βˆ’ 3 βˆ’ 4 5 ] LaTeX: A^{-1} = \frac{1}{det(A)} \begin{bmatrix}5 &4 \\3 & 2\end{bmatrix}
