To determine how many different types of shelves could be ordered, you will multiply all the numbers from each different aspect of the shelves to create all the possible combinations that could occur.
The reason for doing this has to do with the groupings that will occur using all three numbers.
4 x 3 x 6 = 72
There are 72 different possibilities of shelves.
Answer:
None of the above. (Ask your teacher to show you how to work this problem.)
Step-by-step explanation:
Since the results are identical, the matrix of the next three rolls will look exactly like this matrix. (A)
The matrix of all 6 rolls will look like a 6-row matrix with the bottom 3 rows identical to the top 3 rows.
Adding or multiplying A by a constant will not produce these results.
_____
You can replicate columns using matrix multiplication, so you can transpose A, multiply it by a suitable version of an identity matrix, then transpose the result:
((A^T)·[I | I ])^T will turn the 3-row matrix to a 6-row matrix where I is a 3x3 identity matrix. I've used [I | I] here to mean the 3x3 identity matrix is itself replicated horizontally to make a 6-column matrix. ^T indicates transpose.
