(1) Run the Apriori algorithm (mentally, not through any computer program) and compute Ci(candidate itemset) and L; (frequent itemset) for each iteration i. In computing C₁, please applyself-joining and pruning.

A manager has a list of items that have been sorted according to an item ID. Some of them are duplicates. She wants to add a code to the database that assigns a 1 to the item if it is unique, and if there are duplicates, assigns the number of the duplicate. An example is shown below. The first two items are unique, so the repeat code is 1. However, Item ID 37695 is listed six times, so the codes are assigned from 1 to 6, and so on. Explain how to assign the correct code using an IF statement Item ID Repeat Code35080 135222 137695 137695 237695 337695 437695 537695 637712 137722 137757 137757 2 In cell B2 enter 1, and then type a formula into cell B3, followed by dragging the formula down column B until it aligns with the last row in the Item ID column. Which of the following is the correct formula to type into cell B3?
Write Mysql code The database has three tables for tracking horse-riding lessons: Horse with columns: ID - primary key RegisteredName Breed Height BirthDate Student with columns: ID - primary key FirstName LastName Street City State Zip Phone EmailAddress LessonSchedule with columns: HorseID - partial primary key, foreign key references Horse(ID) StudentID - foreign key references Student(ID) LessonDateTime - partial primary key Write a SELECT statement to create a lesson schedule with the lesson date/time, horse ID, and the student's first and last names. Order the results in ascending order by lesson date/time, then by horse ID. Unassigned lesson times (student ID is NULL) should not appear in the schedule. Hint: Perform a join on the Student and LessonSchedule tables, matching the student IDs.
The InstantRide Management team founded a new team for car maintenance. The new team is responsible for the small maintenance operations for the cars in the InstantRide system. The main idea is to take actions faster and minimize the time spent for the maintenance. Therefore, the Car Maintenance team wants to store MAINTENANCE_TYPE_ID (char(5)) and a MAINTENANCE_TYPE_DESCRIPTION (varchar(30)) in the database. Using MAINTENANCE_TYPE_ID as the PRIMARY KEY, create a new table, MAINTENANCE_TYPES, and send the table description with the column names and types to the Car Maintenance team.
