B is false. You cannot square a 3x1 matrix.
In order to multiply matrices, the number of columns of the first matrix must match the number of rows of the second matrix. To square a 3x1 matrix, you would be multiplying a 3x1 by a 3x1; the number of columns in the first one is 1, but the number of rows of the second matrix is 3. They are not compatible.
Answer:
C
Step-by-step explanation:
Convert the fractions into decimals. -2/3 = - 0.7 approximately.
-3/4 = -0.75.
So you have -0.75, -0.7, 0, and 0.7.
Put the negatives first because they have the least value. -0.75 is more negative than -0.7, so it would go first (remember it is really -3/4) , then the next negative -0.7 (-2/3) Zero is neutral so it goes next. Followed by the positive 0.7, which is the greatest.
hope this makes sense and helps. :)
Answer:
(40.6) Is the answer
Step-by-step explanation:
| -72 + 32.4| + 18 / 6 * 3
we do the absolute value first. |-72+32.4| = 39.6
then multiplication (following PEMDAS) 6 * 3 = 18
18 / 18 = 1
39.9 + 1 = 40
Wouldn’t that be a 1 in 3 chance, since their are 3 days?
1/27 is the greater answer
