Group theory Consider the group GL2(Zp) of invertible 2X2 matrices with entries in the field Zp, where p is an odd prime. Zp is an abelian group under addition, the group of unites of Zp is Zpx, which is an abelian group under multiplication. We say (Zp , +, ·) is a field. Show that the subset D2(Zp) of diagonal matrices in GL2(Zp) is an abelian subgroup of order (p - 1)2. For A, B ∈GL2(Zp), show that A and...

A measure of the strength of the linear relationship that exists between two variables is called: Slope/Intercept/Correlation coefficient/Regression equation. If both variables X and Y increase simultaneously, then the coefficient of correlation will be: Positive/Negative/Zero/One. If the points on the scatter diagram indicate that as one variable increases the other variable tends to decrease the value of r will be: Perfect positive/Perfect negative/Negative/Zero. The range of correlation coefficient is: -1 to +1/0 to 1/-∞ to +∞/0 to ∞. Which of...

For matrices, a mulitplicative identity is a square matrix X such XA = AX = A for any square matrix A. Prove that X must be the identity matrix. Prove that for any invertible matrix A, the inverse matrix must be unique. Hint: Assume that there are two inverses and then show that they much in fact be the same matrix. Prove Theorem which shows that Gauss-Jordan Elimination produces the inverse matrix for any invertible matrix A. Your proof cannot...
