Question

1.)You can construct a 3 x 3 matrix of the three columns of point data for the three types of trees. The column of total points is not included in the matrix. Is it possible to find the determinant of the matrix?
a.No. A determinant exists only when the sum of the numbers in the up diagonals is greater than the sum of the numbers in the down diagonals.
b.Yes. A determinant exists only for square matrices.
