5. Fuzzy Logics Consider the following three simple rules to represent fuzzy relationship between food quality and service in a restaurant as input variables and tip amount as output variables. 1) If the food is bad OR the service is poor, then the tip will be low 2) If the service is acceptable, then the tip will be medium 3) If the food is great OR the service is amazing, then the tip will be high. Given the membership functions illustrated in Figure 1 and 2 as follows. Food quality 1.0 0.8 0.6 0.4 0.2 0.0 1.0 0.8 0.6 0.4 0.2 0.0 1.0 0.8 0.6 0.4 0 0.2 0.0 0 Figure 1.

Suppose you are given the following description of a discount policy: An insurance company has a policy of discounting its product to customers under certain circumstances: Discounts of 5% are given only if the customer has excellent credit If the customer has filed less than one claim in the last five years add a discount of 10% If the customer insured multiple products (home, car, boat) etc subtract 4% Represent this situation as a decision table Represent the situation above as a decision tree.
In order to properly define a variable, "type" alone is not sufficient. Every variable has its own specific set of properties, including the data type that corresponds specifically to that variable. How then can we put this concept to use, which gives us the ability to describe the characteristics of any variable?
You build a model predicting blood pressure as a function of three variables: weight (numeric) age (numeric) income (categorical: low, medium, high) You first specify your model as: blood pressure ~ age * income + weight How many parameters (k) does your model have? (Remember, we do not count the grand mean in k) You change the above model specification to be: blood pressure ~ age * income + weight * income How many parameters does your model have now? You change your model to include the three-way interaction (which, remember, includes all two-way interactions and main effects, too!) Your model now looks like this: blood pressure ~ age * income * weight How many parameters does your model have now?
For a variable to be fully defined, its type and any other information it may have must be provided (and therefore complete). All variables, in another way of putting it, have not just a data type but also other qualities. To better describe the characteristics of each variable we encounter, please elaborate on the idea that will help us do so.
Identify the two variables in the example. For direction of variable, put an arrow pointing either up or down to show what direction the variable goes in. For relationship, write “positive” or “negative” to indicate what kind of relationship the two variables have with each other. 1.

Q1: All the following statements about weak and strong entity sets are True, Except: Select one: a. The weak entity set depends on the existence of the strong entity set b. PK of the strong entity set is not explicitly stored with the weak entity set c. An entity set that does not have a primary key is referred to as a weak entity set d. In ER-Diagram, the identifying relationship of a weak entity in represented as a double diamond e. The PK of the weak entity set is only formed by the primary key of the strong entity set Below are two pictures, each with a second and third question

An art museum owns a large volume of works of art. Each work of art is described by an item code (identifier), title, type, and size; size is further composed of height, width, and weight. A work of art is developed by an artist, but the artist for some works is unknown. An artist is described by an artist ID (identifier), name, date of birth, and date of death (which is null for still living artists). Only data about artists for works currently owned by the museum are kept in the database. At any point in time, a work of art is either on display at the museum, held in storage, away from the museum as part of a traveling show, or on loan to another gallery. If on display at the museum, a work of art is also described by its location within the museum. A traveling show is described by a show ID (identifier), the city in which the show is currently appearing, and the start and end dates of the show. Many of the museum works may be part of a given show, and onlyactive shows with at least…
