- You may find it useful to have a spreadsheet open where you can write down these values in a larger table to help keep track. Complete the table below by finding the squares of each of the x-values (for example, if x1 = 5, then x12 = 52 = 25). After you have all five x2 values calculated, add them up and indicate the sum in the bottom row.

Which Boolean operator should Kevin use to do the search that will get the desired results?
- Kevin plans to use a Boolean operator since he wants to learn about two separate things. In order to receive accurate search results, Kevin must choose the proper Boolean operator.TID items_bought 100 {M, O, N, K, E, Y} 200 {D, O, N, K, E, Y} 300 {M, A, K, E} 400 {M, U, C, K, Y} 500 {C, O, K, I, E} Which of the following are maximal itemset in the table above, when minsup is 40%? a. {K, C} b. {M, K} c. {O, N, K, Y}Kevin wants to use a Boolean operator to get information on two topics. Which Boolean operator does Kevin need to employ to get the right search results?
- A company's board consists of 4 people: Abigail (the CEO), Benoit, Charlie, and Debra. When they take a vote, if there is a majority (either up or down), that vote prevails. If, however, there is a tie, then Abigail's vote is the tie-breaker (e.g. if A&B vote up, and C&D vote down, the outcome is "up", because A's vote breaks the tie). The truth table will show all possible combinations of the 4 votes, and the final decision for each.Some rows of the STUGRADE table of a school are shown below: STU_CODE CLS_CODE GRADE YEAR 291 111 3.1 2010 938 101B 2.3 2011 931 M101 3.3 2040 291 M101 3.4 2018 190 111 2.0 2021 931 321 3.9 2003 Suppose that STU_CODE is the student code (foreign key) and CLS_CODE is the class code (foreign key).

- Correct answer will be upvoted else downvoted. table can be addressed as a square shape with stature h and width w, isolated into h×w cells. Let (i,j) signify the cell in the I-th line and the j-th segment of the square shape (1≤i≤h; 1≤j≤w). Into every cell of the table you can either put a plate or keep it unfilled. As every visitor must be situated close to their plate, you can just put plates on the edge of the table — into the first or the last line of the square shape, or into the first or the last segment. Officially, for every cell (i,j) you put a plate into, no less than one of the accompanying conditions should be fulfilled: i=1, i=h, j=1, j=w. To make the visitors agreeable, no two plates should be placed into cells that have a typical side or corner. All in all, if cell (i,j) contains a plate, you can't place plates into cells (i−1,j), (i,j−1), (i+1,j), (i,j+1), (i−1,j−1), (i−1,j+1), (i+1,j−1), (i+1,j+1). Put whatever number plates on the table as could be…Question 3 Ten students have applied for ten fellowship positions in ten schools.
