Explanation Arrow studied fairness criteria on a lot of elections decided by any of the five voting systems. He figured out that not all elections satisfy the four fairness criteria. He found examples of elections using all five methods where some of the fairness criteria failed. Thus, he concluded that, “No voting system can satisfy all four fairness criteria in all cases.” Here is what he found out when he studied all the five voting systems for fairness criteria: Plurality Top-Two Runoff Sequential Runoff Borda Count Pairwise Comparisons Criteria 1 Y Y Y N Y Criteria 2

(3) (4 points) Given three vectors a, b, and c, suppose: |bx c = 2 |a|=√√8 • The angle between a and b xc is 0 = 135º. . Calculate the volume a (bxc) of the parallelepiped spanned by the three vectors.

Calculate these limits. If the limit is ∞ or -∞, write infinity or-infinity. If the limit does not exist, write DNE: Hint: Remember the first thing you check when you are looking at a limit of a quotient is the limit value of the denominator. 1. If the denominator does not go to 0, you should be able to right down the answer immediately. 2. If the denominator goes to 0, but the numerator does not, you will have to check the sign (±) of the quotient, from both sides if the limit is not one-sided. 3. If both the numerator and the denominator go to 0, you have to do the algebraic trick of rationalizing. So, group your limits into these three forms and work with them one group at a time.
