}
The answer is BEDC but how did it come about?
Answers
Answer:
| Circle9(), System.out.print("C");
| Circle9(double radius), System.out.print("D");
| Circle9(double radius, String color, boolean filled) System.out.print("E");
| GeometricObject(String color, boolean filled) System.out.print("B");
Starting From The Bottom -------------------------------
Explanation:
Just debug it.
But you'll get BEDC due to the code arrangement.
In your main: new Circle9();
So, let's go to Circle9()
-----------------------------------------
public class Circle9 extends GeometricObject {
public Circle9() {
this(1.0);
System.out.print("C");
}
--------------------------------------------------
We need to head to Circle9(double radius) because this(1.0) was called, System.out.print("C"); will not be processed just yet
So, let's go to Circle9(double radius)
-----------------------------------------
public Circle9(double radius) {
this(radius, "white", false);
System.out.print("D");
}
--------------------------------------------------
Again, we need to leave this call and head to another, Circle9(double radius, String color, boolean filled), because of this(radius, "white", false); was called System.out.print("D"); will not be processed just yet
So, let's go to Circle9(double radius, String color, boolean filled)
-----------------------------------------
public Circle9(double radius, String color, boolean filled) {
super(color, filled);
System.out.print("E");
}
--------------------------------------------------
So here super is called which just calls the "parent" GeometricObject(String color, boolean filled).
After that, B is outputted to Console
We then print out E
We then print out D
We then print out C
So.... more concise:
Run Through This Backwards
| Circle9(), System.out.print("C");
| Circle9(double radius), System.out.print("D");
| Circle9(double radius, String color, boolean filled) System.out.print("E");
| GeometricObject(String color, boolean filled) System.out.print("B");

Answers
Answer:
An interpreter is quite different from a complier due to the following statement below:
O. An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.
Explanation:
For an interpreter, it works in translating and execution of the codes line after another line. In a situation where there is a mistake in the code, the next line would not be able to be executed, but rather display error message. On the other hand, compiler translate all codes at once and execute them as a single work.
During its translation of the codes in compiler, should there be any error, it would not be able to execute despite the fact that, the error might be in the last line of the code.

Write a function named word_beginnings that has two parameters line a string ch a character Return a count of words in line that start with ch. For the purposes of this exercise a word is preceeded by a space. Hint: add a space to the beginning of line For example if line is 'row row row your raft' and ch is 'r' the value 4 will be returned. Note: You can use lists in this question but try to solve it without lists.
Answers
Answer:
The function in Python is as follows:
def word_beginnings(line, ch):
count = 0
lines =line.split(" ")
for word in lines:
if word[0] == ch:
count+=1
return count
Explanation:
This defines the function
def word_beginnings(line, ch):
This initializes count to 0
count = 0
This splits line into several words
lines =line.split(" ")
This iterates through each word
for word in lines:
This checks if the first letter of each word is ch
if word[0] == ch:
If yes, increment count by 1
count+=1
Return count
return count

When adding delegates to his mailbox, which role should Joel use if he would like the user to be able to read and create items in a particular folder?
- editor
- publishing editor
- author
- manager
Answers
Answer:
publishing editor
Explanation:
In this scenario, the role that he should choose for the delegates would be publishing editor. This role will allow them to create, read, modify, and delete all items within a given folder, and create subfolders. The other options listed either do not give access to create/modify existing files or simply only give all these rights with files that the user creates but not files that already existed in the folder. Therefore, this would be the best role for what Joel wants to accomplish.
Compile and Execute a Program
1. Compile Pay.java using the JDK or a Java IDE as directed by your instructor.
2. You should not receive any error messages.
3. When this program is executed, it will ask the user for input. You should calculate several different cases by hand. Since there is a critical point at which the calculation changes, you should test three different cases: the critical point, a number above the critical point, and a number below the critical point. You want to calculate by hand so that you can check the logic of the program. Fill in the chart below with your test cases and the result you get when calculating by hand.
4. Execute the program using your first set of data.
Record your result. You will need to execute the program three times to test all your data. Note: you do not need to compile again. Once the program compiles correctly once, it can be executed many times. You only need to compile again if you make changes to the code.

Answer:
Best Regards to all of the people who have met you in the class
Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 12-character telephone number in the format: XXX-XXX-XXXX. Acceptable characters (X's) are A-Z and a-z. Your program should check for: The length of the phone number is correct. The dashes are included and are in the correct positions. There are no characters in the illegal characters in the string. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. If the input string is not entirely correct then you should print an error message. For example, if the user enters 555-GET-FOOD the program should display 555-438-3663. If the user enters 123-456-7890, the program should display 123-456-7890. Rules: You must have one function (in addition to main()) that converts an alphabetic character to a digit. Or you can have one function that coverts all characters to digits. You can make your own function or use a built-in function if one exists.

in cell B5 create a formula using round function that rounds the value in cell G19 to an integer, with 0 decimal places
Answers
Answer:
=ROUND(G19, 0)
Explanation:
In Microsoft Excel you would need to click on cell B5 and then click the function bar at the top and paste the following formula
=ROUND(G19, 0)
This formula will grab whatever value is in cell G19 and round it to the nearest whole integer without any decimal places at all. This is handled by the ROUND() method which takes in two arguments, the first is the cell which has the value to be rounded, and the second argument is the number of decimal places to round to. 0 indicates no decimal places.

Explanation:
Microsoft Excel is a software application or program designed and developed by Microsoft Inc., for analyzing and visualizing spreadsheet documents.
The document that is use in excel to store a work with data that's formatted in a pattern of uniformly spaced horizontalal and vertical lines is called a spreadsheet.
A spreadsheet can be defined as a file or document which comprises of cells in a tabulated format (rows and columns) typically used for formatting, arranging, analyzing, storing, calculating and sorting data on computer systems.
Additionally, workbooks are known as Microsoft Excel files. An Excel workbook can be defined as a collection of one or more charts and worksheets (spreadsheets) used for data entry and storage in an excel file. In order to create a project on Excel you will have to use a workbook.
In this problem, you should write one function named count_calories. This function should have one parameter, which will be a dictionary of food items. The keys will ne the name of a food item (such as 'granola' or 'steak'), and the value associated with each food will be the integer calorie amount for that food. The function should iterate through all of the foods and sum up the total calories, and then return that number. For example:
count_calories({'chocolate':200, 'milk':120, 'steak':250}) should return 570.
count_calories({'carrot':5, 'apple':50}) should return 55.
Make sure to include only the one function in your file.

You need to write a menu driven program. The program allows a user to enter five numbers and then asks the user to select a choice from a menu. The menu should offer the following four options – 1. Display the smallest number entered 2. Display the largest number entered 3. Display the sum of the five numbers entered 4. Display the average of the five numbers entered
Answers
Answer:
In Python:
nums = []
for i in range(5):
num = int(input("Num: "))
nums.append(num)
print("1 - Smallest")
print("2 - Largest")
print("3 - Sum")
print("4 - Average")
menu = int(input("Select menu: "))
if menu == 1:
print("Smallest: ",min(nums))
elif menu == 2:
print("Largest: ",max(nums))
elif menu == 3:
isum = 0
for i in range(5):
isum+=nums[i]
print("Sum: ",isum)
elif menu == 4:
isum = 0
for i in range(5):
isum+=nums[i]
print("Average: ",isum/5)
else:
print("Invalid Menu Selected")
Explanation:
This program uses a list to get inputs for the 5 numbers
Here, the list is initialized
nums = []
This iterates from 1 to 5
for i in range(5):
This gets input for the 5 numbers
num = int(input("Num: "))
This appends each number to the list
nums.append(num)
The next 4 lines represents the menu
print("1 - Smallest")
print("2 - Largest")
print("3 - Sum")
print("4 - Average")
This prompts the user for menu
menu = int(input("Select menu: "))
If menu is 1, print the smallest
if menu == 1:
print("Smallest: ",min(nums))
If menu is 2, print the largest
elif menu == 2:
print("Largest: ",max(nums))
If menu is 3, calculate and print the sum of all inputs
elif menu == 3:
isum = 0
for i in range(5):
isum+=nums[i]
print("Sum: ",isum)
If menu is 4, calculate and print the average of all inputs
elif menu == 4:
isum = 0
for i in range(5):
isum+=nums[i]
print("Average: ",isum/5)
If menu is not 1 to 4, then print invalid menu
else:
