Given this general matrix multiplicaiton problem, explain how you would know where to place the answer in matrix [c] that corresponds to the work you did with row vector 2 from matrix [a] and column vector 1 from matrix [b].

  the row and column descriptors identify the row, column of the sum of products.

Step-by-step explanation:

The position of the product is at the same row and column as the row vector and column vector you're working on.

The work you did with row vector 2 from Matrix [A] and column vector 1 from matrix [B] will show up in row 2, column 1 of matrix [C].

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
