In this exercise you will work with LU factorization of an matrix A. Theory: Any matrix A can be reduced to an echelon form by using only row replacement and row interchanging operations. Row interchanging is almost always necessary for a computer realization because it reduces the round off errors in calculations - this strategy in computer calculation is called partial pivoting, which refers to selecting for a pivot the largest by absolute value entry in a column. The MATLAB...

Have to show work for every problem 4. A company uses three plants to produce a new computer chip. Plant A produces 30% of the chips. Plant B produces 45% of the chips. The rest of the chips are produced by plant C. Each plant has its own defectiv rate. These are: plant A produces 3% defective chips, plant B produces 1% defective chips, plant C produces 5% defective chips. Hint: draw a tree diagram. (a) Construct a tree diagram...

**DO IT AS PYTHON PLEASE** The Trifid Cipher General Problem Description The Trifid cipher (not to be confused with the creatures from the classic science-fiction film "The Day of the Triffids") is an algorithm that enciphers a plaintext message by encoding each letter as a three-digit number and then breaking up and rearranging the digits from each letter's encoded form. For this assignment, you will create a set of Python functions that can encode messages using this cipher (these functions...
