SUNSHINE AIRLINE COMPANY The ER Diagram for the SUNSHINE AIRLINE COMPANY is based on the following: - For each airplane type, we keep track of a unique airplane type ID (AirplaneTypelD), number of engines (NoOfEngines), and number of seats (NoOfSeats). - For each airport, we keep track of a unique airport ID (AirportID), and the length of the main runway (LengthOfRunway). - Each airplane type is able to land at one airport at least, but may be able to land at many airports. Each airport accommodates landing of at least one airplane type, but may accommodate landing of more airplane types.

7-2 Discussion: Interpreting Multiple Regression Models Previous Next In this discussion, you will apply the statistical concepts and techniques covered in this week's reading about multiple regression. You will not be completing work in Jupyter Notebook this week. Instead, you will be interpreting output from your Python scripts for the Module Six discussion. If you did not complete the Module Six discussion, please complete that before working on this assignment. Last week's discussion involved development of a multiple regression model that used miles per gallon as a response variable. Weight and horsepower were predictor variables. You performed an overall F-test to evaluate the significance of your model. This week, you will evaluate the significance of individual predictors. You will use output of Python script from Module Six to perform individual t-tests for each predictor variable. Specifically, you will look at Step 5 of the Python script to answer…

PART I: Given the following UML diagram. Answer the following questions PCRTest - newNum: int //-- auto-increment patientName: String previousResult: int //-- should be less than 35 - currentResult: int //-- should be less than 35 + PCRTest (patientName: String, previousResult: int) +setcurrentResult (int r):void +getcurrentResult () : int +isRecovered () : boolean +tostring () : String + GenerateCode (): String //-- explained in part III Question PCRTest as weir as the constructor and the setter and getter of the currentResult. Note that: • The attribute newNum is incremented when a PCRTest object is created. It represents the total ): Implement all the data fields represented in the UML diagram of the class number of tests. • The constructor accepts the patient's name and the previous test result. The value of previousResult and currentResult should be between 0 and 35. • The method setcurrentResult(int r) assigns the value r to the currentResult attribute. The method…

Q1: What are some features and benefits to structured data? Check all that apply. Group of answer choices A method can be passed a structure and the method can then process multiple data items in a structure. 1: Related data items can be under 1 structure definition. 2: Programmers can code structures as they see fit. 3: Structures can be used in arrays to simplify some programming tasks. 4: Multiple variables can be defined using the same structure. Q2: Enumerations are representing constant values and are therefore required to be coded in uppercase characters. True False Q3: Enumerations are stored in memory as ______ . Group of answer choices Integer 1: String 2: Pointer to an internal variable 3: Internal array Q4: Why did the author include enumerations in the same chapter as structured data? Check all that apply. 1: Enumerations are a programmer-defined data type, similar to structured data types being programmer-defined. 2: You can't have structured…
5. calculate_new_balance Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")]) 270 >>> calculate_new_balance (100, []) 100
To declare a variable, "type" alone is not enough. Every variable is distinguished by its data type and a set of additional characteristics. So how can we make use of this idea, which allows us to describe any variable's properties?
