Question

E.
The relationship a=b indicates that a and b are equivalent. The relationship asb indicates
that a and b are congruent. You may shortcut this symbol by underlining an equal symbol such
as. To find congruence for some b mod n, divide b by n and take the remainder (r) as the
answer. Put your answers in terms of mod 2. For example, to determine (72 mod 2) determine
the remainder 72/2 = 36 r 0 therefore, 72 mod 2 = 0 mod 2 since 0 is the remainder or 72/2.
a. 24 mod 2 =
b. 13 mod 2 =

d. 29 mod 2
F.
Consider a 12-hour clock. People can add hours to calculate another time. All values on the

Let's revisit our first problem, where we want to set up a series of chess matches so we can rank six players in our class. As we did before, we will assume that everyone keeps their chess rating a private secret; however, when two players have a chess match, the person with the higher rating wins 100% of the time. But this time, we are only interested in identifying the BEST of these six players and the WORST of these six players. (We don't care about the relative ordering or ranking of the middle four players.) Your goal is to devise a comparison-based algorithm that is guaranteed to identify the player with the highest rating and the player with the lowest rating. Because you are very strong at Algorithm Design, you know how to do this in the most efficient way. Here are five statements. A. There exists an algorithm to solve this problem using 6 matches, but there does not exist an algorithm using only 5 matches. B. There exists an algorithm to solve this problem using 7 matches,…
There are three financial aid counselors. If a student’s last initial is from A – H, let them know that their counselor is Jon Stewart. If a student’s last initial is from I – Q, let them know that their counselor is Chelsea Handler. If a student’s last initial is from R – Z, let them know that their counselor is Brian Williams.Ask student for the FICO score, if it’s less than 660 tell that this student cannot have a loan.
Suppose there are 100 items, numbered 1 to 100, and also 100 baskets, also numbered 1 to 100. Item i is in basket b if and only if i divides b with no remainder. Thus, item 1 is in all the baskets, item 2 is in all fifty of the even-numbered baskets, and so on. Basket 12 consists of items {1, 2, 3, 4, 6, 12}, since these are all the integers that divide 12. Answer the following questions: a. If the support threshold is 5, which items are frequent? (4 marks) b. What is confidence when the association rule is {5, 7} → 2 (2 marks) c. Considering the support threshold as 4, what are the candidate item sets for size 2 (pairs) (i.e., C2) while applying the A-Priori Algorithm. (2 marks)
