Answer:

det(A)=-det(B)

Step-by-step explanation:

We have two matrices A, and B.

Matrix B is obtained by swapping rows 1 and 3 of matrix A.

Whenever we swap rows in matrices, the determinants does not change but the sign changes.

Therefore

det(A)=-det(B)

Also no two rows of of both matrices are the same, therefore

det(A)≠0, and det(B)≠0

Kaylis [27]

Answer:

Best prediction is 8.5 hours.

Step-by-step explanation:

Since there is no samples for the age of 16 years, the best estimate (prediction) would be to interpolate: compute the average between values of the neighboring ages, namely 8 and 9 (approximately). The closest choice to an average like that is 8.5 hours.
