Bargain Bob's auto dealership sells vehicles. He sells Chrysler, Jeep, and Dodge brand vehicles. He tracks customer and manufacturer. Bob tracks only the main owner—all co-owners and co-signers are recorded elsewhere.Based on the description above, what is the maximum cardinality between each instance of "Customer" and "Vehicle?"

Answer:

A)

Explanation:

In this code example the missing piece of code would be...

public void setHourly(String isHourly)

This piece of code is creating a function called setHourly which takes in one String variable as it's parameter. Based on the rest of the code, the function takes that parameter variable and places it into an instance variable called Hourly which can be used when the function is called.

The electric bill program illustrates the use of loops (i.e. iteration)

Loops are used to execute repetitive operations

The electric bill program in Python where comments are used to explain each line is as follows:

#This iteration shows that the process is repeated for 50 consumers

for i in range(50):

   #This gets input for the consumer name meter number

   mno = input("Consumer name meter number: ")

   #This gets input for last month reading

   lmr = int(input("Last month reading: "))

   #This gets input for current month reading

   cmr = int(input("Current month reading: "))

   #This calculates the number of units

   Nou = cmr - lmr

   #This calculates the bills

   bill = Nou*2

   #This calculates the tax

   tax = bill*0.15

   #This calculates the netbills

   netbill = bill+tax

   #This next four lines print the electric bills

   print("Number of units:",Nou)

   print("Bills:",bill)

   print("Tax:",tax)

   print("Netbill:",netbill)

Answer:

The Java code is given below with appropriate comments

Explanation:

import java.util.Scanner;

public class Temperature {

  public static void main(String[] args)

  {

      // declaring the temperatures array

      double[] maxTemp = new double[12];

      double[] lowTemp = new double[12];

      double avgHighTemp = 0;

      double avgLowTemp = 0;

      Scanner kb = new Scanner(System.in);

      System.out.println("Please enter the highest and lowest temperatures");

      System.out.println("of each month one by one below\n");

      // inputting the temperatures one by one

      for(int i = 0; i < 12; i++)

      {

          System.out.print("Please enter the highest temperature for month #" + (i+1) + ": ");

          maxTemp[i] = Integer.parseInt(kb.nextLine());

          System.out.print("Please enter the lowest temperature for month #" + (i+1) + ": ");

          lowTemp[i] = Integer.parseInt(kb.nextLine());

          System.out.println();

      }

      avgHighTemp = getAvgHighTemperature(maxTemp);

      avgLowTemp = getAvgLowTemperature(lowTemp);

      System.out.printf("Average high temperature is: %.2f\n", avgHighTemp);

      System.out.printf("Average low temperature is: %.2f\n", avgLowTemp);

  }

  // method to calculate the average high temperature

  public static double getAvgHighTemperature(double[] highTemp)

  {

      double total = 0;

      for(int i = 0; i < 12; i++)

      {

          total += highTemp[i];

      }

      return total/12;

  }

  // method to calculate the average low temperature

  public static double getAvgLowTemperature(double[] lowTemp)

  {

      double total = 0;

      for(int i = 0; i < 12; i++)

      {

          total += lowTemp[i];

      }

      return total/12;

  }

}

The purpose of creating a PST file is to

c) To save your emails so that you can restore your mailbox if necessary

Explanation:

• A PST file is a personal folder file in Microsoft Outlook. In Outlook, the storage limit for a single user's . PST file is 2 GB. PST stands for personal storage.
• A PST file, or personal storage table (. pst) file, is a Microsoft Outlook Data File that stores a user's Outlook data for POP3, IMAP and web-based mail accounts, including all mail folders and the items within the folders, such as emails, email attachments, to do items and appointments, contacts and more.
• In computing, a Personal Storage Table (. pst) is an open proprietary file format used to store copies of messages, calendar events, and other items within Microsoft software such as Microsoft Exchange Client, Windows Messaging, and Microsoft Outlook.
• The purpose of the PST file was, like it is today, to provide end users with a way to create local archives of their server-based email.
• As a result, PST files provided end users with a means of expanding their email storage by creating and maintaining one or more local archives.

Answer:

def ViewRatings(str, rating):

   for book in books:

       if r >= rating:

           print(book)

ViewRatings("emma", 3)

Explanation:

* The code is in Python.

Since the are missing parts in your question. I am assuming there is a books list and there is a rating, r for each book.

- Create a function called ViewRatings that takes two parameters

- Initialize a for loop that iterates through each book in the books list

- For each book, check its rating with given rating. If the rating of the book is greater than or equal to given rating, print the book

- Call the function

To represent the 5 children as a computer bit, we make use of the equation . 3 bits are required to represent the 5 children.

Given that

---- number of children

The number of bits (b) is calculated as:

Substitute 5 for n

Take logarithm of both sides

Apply law of logarithm

Make b the subject

The number of bits must be an integer. So, we use the greatest integer closest to 2.32. The integer is 3

So:

Hence, the number of bits to represent the 5 children is 3.
