Write one or two paragraphs comparing and contrasting all methods of solving systems of linear equations with two variables. Explain which method you prefer and why. Support your answer by providing appropriate examples.
Solution Summary
Neat and step-by-step answers with different examples are provided.
Suppose X is a measurable space, E belongs to the sigma algebra ( I believe to the sigma algebra in X) , let us consider X\E = Y. Show that all sets B which can be expressed as A\E, where A belongs to the sigma algebra in X, form a sigma-algebra in Y.
Please justify every step and claim you make in the solution.
1. Very rarely do people use algebra in their jobs or their lives. At most, people use arithmetic. If this is the case then why do you suppose it is that we study algebra in the first place?
Should algebra be taught to everyone? Who should study algebra? The statements below serve as possible answers to these questions and are only 'food for thought.' I welcome your constructive ideas and comments on one or several of them.
Whether you agree or do not agree, the study of algebra is good for the brain. The b
The drying time of varnish depends on the amount of certain chemical that s added.
a. Determine a best (least-squares) ft parabola of the form:
T(m) = x1 + x2m + x3m^2 to the data provided n the table below
b) Also, estimate the drying time of the varnish when 3.5 grams of the chemical are added.
Mass (m) of Additive (Gr
