The model, year, color, and price need to be recorded for each car, plus any additional features for the different types of cars. The program must allow the dealer to: • Add a new car to the lot • Remove a car from the lot • Correct any data that's been entered Display information for any car The software developer decides to have these classes: Car, Inventory, Sedan, SUV, and StationWagon. Choose the correct answer after considering the following statements: 1. There are no inheritance relationships between these classes. 2. The Inventory class has-a list of Car objects. 3. The Sedan, StationWagon, and SUV classes are independent of each other. O Only 1 and 2 are true O Only 2 is true O Only 2 and 3 are true O Only 1 is true O Only 3 is true

A car dealer needs a program that will maintain an inventory of cars on the lot. There are three
types of cars: sedans, station wagons, and SUVS. The model, year, color, and price need to be
recorded for each car, plus any additional features for the different types of cars. The program
must allow the dealer to:
• Add a new car to the lot
Remove a car from the lot
• Correct any data that's been entered
• Display information for any car
The software developer decides to have these classes: Car, Inventory, Sedan, SUV, and
StationWagon. Choose the correct answer after considering the following statements:
1. There are no inheritance relationships between these classes.
2. The Inventory class has-a list of Car objects.
3. The Sedan, StationWagon, and SUV classes are independent of each other.
O Only 1 and 2 are true
O Only 2 is true
O Only 2 and 3 are true
O Only 1 is true
O Only 3 is true

Computer Science Part 1: Write a script that creates and calls a stored procedure named online sales. First, code a statement that creates a procedure that adds a new row to the SalesOrderHeader table. Then code a call that tests this procedure. Part 2: Create a stored procedure using the product and product inventory table. This stored procedure should declare a variable and set it the count of all products in the product table. If the count is greater than or equal to 20 the stored procedure should display a message that says "Inventory count is greater than or equal to 20". Otherwise, it should say "Inventory count for the products is less than 20".

BAGGINS Trucking maintains a trip file in which each record contains the following data:DRIVER nameMILES driven on tripHOURS driven on trip Design an application that inputs records from the file (until reaching "eof") and, for each record, displays the DRIVER's name and the average Miles-per-Hours (MPH) for the trip where MPH is calculated by dividing the MILES by the HOURS. The program should also accumulate a GRAND total of the MILES driven. At the end, the program should display the GRAND total of the MILES driven. For example, if the trip file contained the following:Smith, 300, 5Williams, 750, 10Jones, 880, 11 then the program should display:Smith averaged 60 mphWilliams averaged 75 mphJones averaged 80 mphGrand total of miles is 1,930 Pseudocode:
Consider a system of three independent, periodic real-time tasks: T1= (4, 3), T2 = (12,7), and T3 = (8, 5). Construct the schedule for these tasks in the interval [0, 24) with q=1 on twoprocessors with PF. Note that there are many PFair algorithms, while PF is one of them. PF prioritize subtasks by deadlines, and break ties by inspecting future subtask deadlines. Also, if a currently-executing job ties with a newly- released job, then continue executing the currently-executing job; break any other ties by task ID (T1 = highest, T3 = lowest). a. Show all sub jobs’ releases and deadlines for (the first job of) each task. Note that q=1 so each sub job should have execution requirement of 1b. Show the PF schedule.c. Will this task set be schedulable with q=2? Please explain.
PYTHON PROGRAMMING LANGUAGE Create a new text document called names.txt (this is done by hand - not using programming) with the following names: Adam, Bryan, Charlie. Each name should be followed by a hard return (do not store them in a list). Main Function. Write a program where the user enters a name. Using the read function, check to see if the name is in the text document. If it is, respond back to the user the name is found within the list. Read Function. The read function should return the contents of the text document as a list. Write Function. The write function should take the list and override the file with the new names list in reverse alphabetical order with a hard return after each name.

Create the following variables that can be used to store values. Use the naming conventions as outlined in the Algorithms/Pseudocode Guidelines document in the course resources section of the course. 1. test grade for student test 2. total of all test grades added together 3. the average for the test grades Create an assignment statement that sets the value of the variable you created to store the value of all test grades added together to zero. You may refer to Table 6.1 in Chapter 6 for examples. Create an input statement to input the value for the first test grade for the variable you created. Create an algorithm that will obtain the test grade for three students, add the test grades together, calculate the average of the test grades, and output the average. Use a count-controlled loop to create the algorithm. Use the information from your answers to questions 3, 4, and 5 in the creation of your algorithm. Also use information and examples from Chapter 6…
