Answer:
so the chances are a 4 of 10 chance
Step-by-step explanation:
black:1
striped:3
white:6
add those but also think about how you have a white marble changing to striped so you get your total which is 10 and the of is the striped marbels which is now 4
B. (Not sure)
(5+A)
———
(a-1)
This angle is classified as an obtuse angle
Answer:
Step-by-step explanation:
We want to find the inverse of
To find the inverse matrix, augment it with the identity matrix and perform row operations trying to make the identity matrix to the left. Then to the right will be inverse matrix.
So, augment the matrix with identity matrix:
- Subtract row 1 multiplied by 4 from row 2
- Add row 1 multiplied by 4 to row 3
- Subtract row 2 multiplied by 2 from row 3
- Add row 3 multiplied by 2 to row 1
- Subtract row 3 multiplied by 11 from row 2
As can be seen, we have obtained the identity matrix to the left. So, we are done.
