Answer:
It was approximately a 9% decrease. (If you need to round to the nearest tenth, 9.1. If you need to round to the nearest hundredth, 9.10).
Step-by-step explanation:
I am going to assume that the question means that Andrea could have earned 220 points on the assignment, but instead because the assignment was late, she was marked down 20 points. (Reduced to 20 points is kind of awkward wording).
Given that, 20 divided by 220 comes out to 0.0909 repeating.
0.09, as a percentage, is 9%. (Again, 0.0909, 9.09%, could be rounded up to 9.1%).
Hope this helps!

Step-by-step explanation: I think you multiply 3 times 3 because the other circle circle has an option the first doesn't have have.
Answer:
Step-by-step explanation:
It is a result that a matrix is orthogonally diagonalizable if and only if is a symmetric matrix. According with the data you provided the matrix should be
We know that its eigenvalues are , where has multiplicity two.
So if we calculate the corresponding eigenspaces for each eigenvalue we have
,.
With this in mind we can form the matrices that diagonalizes the matrix so.
and
Observe that the rows of are the eigenvectors corresponding to the eigen values.
Now you only need to normalize each row of dividing by its norm, as a row vector.
The matrix you have to obtain is the matrix shown below
If 0.4 liters is 1/2000 of the production batch, then the production batch is 2000 * 0.4 liters
2000 * 0.4 liters = 800 liters
