Answer 1

I’m not sure what you want done with this. It looks like a table with column headings A, B, C and two rows of values:

Row1: -12, 1, 64
Row2: 1, 12, 64

Do you want me to:
- compute sums/averages,
- treat these as vectors and check independence or compute dot products,
- solve a system (if there are missing right-hand sides),
- something else?

Quick calculations in case they help:
- Column sums: A: -12+1 = -11; B: 1+12 = 13; C: 64+64 = 128
- Column means: A: -5.5; B: 6.5; C: 64
- Row sums: Row1 = -12+1+64 = 53; Row2 = 1+12+64 = 77
- Row means: Row1 ≈ 17.6667; Row2 ≈ 25.6667
- Row2 − Row1 = (13, 11, 0)

Tell me which of these (or something else) you want me to do.
