Please see attached file Solve all these problems using matrix inverses. You have seen these problems before and have used other means to solve them, please disregard those solutions and solve these using only matrix inverses.

I am unclear as to how some scalars have been calculated. I know what the two vectors and the inverse covariance variance matrix are but please could you clarify the operations required to compute into a single number? There is also a set of data on page two that needs computing along with a general explanation of how to do it.

Problem1.How are the inverse Matrices used to solve linear systems. Explain in your own words with example. Problem 2. In the matrix Algebra why does there have to be right and left distributive properties.

The problems I need solved are attached. Please provide as much detail as possible and include comments for the code done in MATLAB, so I can understand. Thanks Assume that a computer can perform 10^6 multiplications per second. Estimate the time that it would take to evaluate the determinant of a 100x100 matrix...

Gretchen Schmidt plans to buy shares of two stocks. One costs $32 per share and pays dividends of $1.20 per share. The other costs $23 per share and pays dividends of $1.40 per share. She has $10,100 to spend and wants to earn dividends of $540. How many share of each stock should she buy? Use the form of " AX=B " equation

I need an example of a matrix that has more than one solution.

I need an example of a matrix that has no solution. I also need to know how to use row operations to show why the problem has no solution.

Can you explain to me how these problems are solved? (Please see the attached questions file).

Please help me by showing how these problems on matrices are worked out. (See the Attached Questions File) Answer all questions and show work 1. Find: 2. Find the inverse of: 3. Compute the transpose of A = 4. Introduce slack variables and set up the initial tableau. Do not solve. M

This problem was a sample exam question taken from a text book. This problem is about showing a matrix is TU. This problem can be found in the Wolsey text book called "Integer Programming". A useful resource is "Integer and Combinatorial optimization" by Wolsey and Nemhauser.

I need a matrix with no solution, use row operations to matrix that has no solution. Use row operations to show why it has no unique solution. Also some matrices that have more then one solution (in fact, an infinite number of solutions) because the system is undetermined. (In other words, there are not enough constraints
