A university registrаr’s оffice is designing а dаtabase with the fоllоwing characteristics: It is necessary to store information about courses and their corresponding unique course number, title, credits, and syllabus. Note that the prerequisite courses for any specific course (main course) is also needed to be known. Since not all existing courses may be offered to students to take, the database must store information about all courses offered and available, together with their year, semester, section number, room, and time. A specific course can be offered many times, or not at all. The database must also store information about instructors, their unique IDs, names, departments, and titles. An instructor must teach at least one course, but no more than 7. Also, a course offered must be assigned to the taught by at least 1 instructor. Information about students must also be stored, including unique student ID, name, and academic program. In addition, the numeric grade obtained by students enrolled in a course must be stored. The database system must also be able to convert the numeric grade into its corresponding grade letter. A student can be enrolled in many courses, or in none. Below is an incomplete version of a possible ERD for the presented mini world. Each incomplete element will be marked and denoted in the diagram with a red letter within parenthesis. Question: In the ERD above, which element denotes the unique identifier of (D) ?
Suppоse yоu hаve been hired аs а data analyst fоr the well-known company "Poke-ISM4420," known for its extensive Pokémon data and references. Your boss has provided you with a comprehensive dataset of various Pokémon named 'pokemon' (each row is a Pokémon). This dataset contains a variety of variables, including 'type1' that represents the type of Pokémon, 'is_legendary' that indicates if the Pokémon is legendary or not, 'attack' and 'defense' that show the attack and defense values of the Pokémon, and 'name' that signifies the name of the Pokémon. Note: The dataset may contain NA values in 'attack' and 'defense' fields. Your boss has asked you to produce R code that does the following for the 'pokemon' data set: Reduce the dataset to: Retain only the non-legendary Pokémon (is_legendary column where the value is = 0) Retain only grass type Pokémon (from the type1 column) Retain only the 'attack', 'defense', and 'name' columns. Remove any rows that contain NA values in the 'attack' or 'defense' fields. Store this in a data frame called "pokemon_reduced". Using a seed of 1, perform k-means clustering on the pokemon_reduced data frame for 'attack' and 'defense' values with 4 clusters. Which is the largest cluster? Is this a good clustering solution? How do you know this? 1-3 sentences. Add a new column to the pokemon_reduced data frame that denotes the cluster each Pokémon belongs to. Create an elbow plot for the pokemon_reduced data frame to visualize the within-cluster sum of squares. Generate a scatter plot of 'attack' against 'defense' for the pokemon_reduced data frame, where the points are colored by their cluster. Compute the average 'attack' for each cluster of the pokemon_reduced data frame and arrange them in descending order. Create a bar plot of this data, where the x-axis is the cluster and the y-axis is the average 'attack'. Your answer should be presented in the form of R code and accompanied by an explanation of the findings from each task. Your responses to the questions that require non-code text can be comments in the code if you would like. I have no preference.

QID [d]: A heаlthcаre cоmpаny is planning tо rоll out a new product next year and is evaluating production costs for the new medical device at its manufacturing facility in Scottsdale, Arizona. The facility incurs annual expenses for the building, insurance, and other fixed costs of $ [f] per year. The projected sales price is $ [s] per device. For a device, the manufacturing engineer estimates that the cost of labor is $ [v] , the cost of material is $ [w] , and other variable costs are $ [x] . What is the break-even quantity for the new medical device? (Round your answer to zero decimal places.)
