Week 6
Mat210 Review of Solving Systems of Equations
1. One year a couple invested $10,000 in two projects. The first investment had a 6% profit and the other had a 12% profit. Their investments made $960, how much was invested at each rate? Write a system of equations and solve using any method you wish.

Solve each system using the method indicated.

By Substitution:
2. x – y = 4 3. x = y – 4
2x + y = 5 2x + 3y = 7

by Addition:
4. 5x + 6y = 12 5. 2x – 3y = 16
10x = – 12y + 24 -4x + y = – 22

Week 7

1. y > 3x – 5 3. -8y ≤ 40

2. -3y < x - 12 4. 4x + 2y ≥ 4 Week 7, 216 13.12 State the four assumptions required for one-way ANOVA. How crucial are these assumptions? 13.13 One-way ANOVA is a procedure for comparing the means of several populations. It is the generalization of what procedure for comparing the means of two populations? 13.14 If we define s = √ MSE, of which parameter is s an esti- mate?
