Answer: Matrix B is non- invertible.
Step-by-step explanation:
A matrix is said to be be singular is its determinant is zero,
We know that if a matrix is singular then it is not invertible. (1)
Or if a matrix is invertible then it should be non-singular matrix. (2)
Given : A and B are n x n matrices from which A is invertible.
Then A must be non-singular matrix. ( from 2 )
If AB is singular.
Then either A is singular or B is singular but A is a non-singular matrix.
Then , matrix B should be a singular matrix. ( from 2 )
So Matrix B is non- invertible. ( from 1 )
Four percent of 56 is 2.24

Step-by-step explanation:
This would be easiest with a graphing calculator.
I recommend changing the mixed fractions to improper ones (so change 2 and 5/6 to 17/5, 1.75 to 7/4, 2 and 1/3 to 7/3, 1.1 to 11/10 and lastly 1.6 to 8/5) If you wish to change .14 to 14/100 and then reduce it to 7/50, then do so.
Your answer should be 1.21.
On a calculator, type in ((17/50+(7/4)x(7/50)). Hit enter. Then input ((7/3)x(11/10)/(8/5)). Hit enter. Then divide the top number and the bottom number.
