1. Suppose that both sides of a system of linear equations Ax = b are multiplied by a nonzero scalar a. (a) Does this change the true solution x? (b) Does this change the residual vector r for a given x? (c) What conclusion can be drawn about assessing the quality of a computed solution?

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear re…

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
