Explanation:
Let K(x, y) denote the statement "x knows y" and D denote the domain of all people. Express the following English sentences as a quantified proposition using the definitions above:
1. Everybody knows somebody.
2. There is somebody that no one knows.
3. There is no one who knows everybody
Answer:
Given: K(x,y) denotes statement:
"x knows y"
D denote domain of all people.
Explanation:
1. Everybody knows somebody.
Solution:
∀x∈D ∃y∈D : K(x, y)
∀ means for all. Here it is used for Everybody.
∃ means there exists some. Here it represents Somebody.
∈ means belongs to . Both x and y belongs to the domain D of all people.
2. There is somebody that no one knows.
Solution:
∀x∈D ∃y∈D : ¬K(x, y)
∀ means for all. ∃ means there exists some. ∈ means belongs to both x and y belongs to the domain D of all people.¬ this is negation sign which means not K(x,y). So the negation of everybody knows somebody can be expressed as there is somebody that no one knows.
3. There is no one who knows everybody
Solution:
This can be represented in both the ways below.
∀ y∈D ∃ x∈D : K(x, y)
∀ means for all. ∃ means there exists some. ∈ means belongs to both x and y belongs to the domain D of all people.
∀x∈D ∀y∈D : ¬K(x, y)
∀ means for all. The negation shows that there is no one who knows everybody.
#Write a function called "scramble" that accepts a string #as an argument and returns a new string. The new string #should start with the last half of the original string #and end with the first half. # #If the length of the string is odd, split the string #at the floor of the length / 2 (in other words, the second #half is the longer half). # #For example: # scramble("abcd") -> "cdab" # screamble("abcde") -> "cdeab" # scramble("railroad")) -> "roadrail" # scramble("fireworks")) -> "worksfire"
Answer:
def scramble(s):
if len(s) % 2 == 1:
index = int(len(s)//2)
else:
index = int(len(s)/2)
return s[index:] + s[:index]
Explanation:
Create a function called scramble that takes one parameter, s
Check the length of the s using len function. If the length is odd, set the index as the floor of the length/2. Otherwise, set the index as length/2. Use index value to slice the s as two halves
Return the second half of the s and the second half of the s using slice notation (s[index:] represents the characters from half of the s to the end, s[:index] represents the characters from begining to the half of the s)

The function file_stats should calculate three statistics about in_file i.e. the number of lines it contains, the number of words and the number of characters, and print the three statistics on separate lines.
For example, the following would be be correct input and output. (Hint: the number of characters may vary depending on what platform you are working.)
>>> file_stats('created_equal.txt')
lines 2
words 13
characters 72
Answer:
Here is the Python program.
characters = 0
words = 0
lines = 0
def file_stats(in_file):
global lines, words, characters
with open(in_file, 'r') as file:
for line in file:
lines = lines + 1
totalwords = line.split()
words = words + len(totalwords)
for word in totalwords:
characters= characters + len(word)
file_stats('created_equal.txt')
print("Number of lines: {0}".format(lines))
print("Number of words: {0}".format(words))
print("Number of chars: {0}".format(characters))
Explanation:
The program first initializes three variables to 0 which are: words, lines and characters.
The method file_stats() takes in_file as a parameter. in_file is the name of the existing text file.
In this method the keyword global is used to read and modify the variables words, lines and characters inside the function.
open() function is used to open the file. It has two parameters: file name and mode 'r' which represents the mode of the file to be opened. Here 'r' means the file is to be opened in read mode.
For loop is used which moves through each line in the text file and counts the number of lines by incrementing the line variable by 1, each time it reads the line.
split() function is used to split the each line string into a list. This split is stored in totalwords.
Next statement words = words + len(totalwords) is used to find the number of words in the text file. When the lines are split in to a list then the length of each split is found by the len() function and added to the words variable in order to find the number of words in the text file.
Next, in order to find the number of characters, for loop is used. The loop moves through each word in the list totalwords and split each word in the totalwords list using split() method. This makes a list of each character in every word of the text file. This calculates the number of characters in each word. Each word split is added to the character and stored in character variable.
file_stats('created_equal.txt') statement calls the file_stats() method and passes a file name of the text file created_equal.txt as an argument to this method. The last three print() statements display the number of lines, words and characters in the created_equal.txt text file.
The program along with its output is attached.

Two-factor authentication can best be breached by the adversary using:________. a. social engineering attack b. using sniffers like Wireshark and capturing packets c. using rootkits and privilege escalation to get to the kernel processes d. using a virus and destroying the computer that stores authentication information.
Answer:
a. social engineering attack
Explanation:
Two-factor authentication requires that the user/owner of the account enter a second verification code alongside their password in order to access the account. This code is usually sent to a personal phone number or email address. Therefore in order to breach such a security measure the best options is a social engineering attack. These are attacks that are accomplished through human interactions, using psychological manipulation in order to trick the victim into making a mistake or giving away that private information such as the verification code or access to the private email.
7d2b:00a9:a0c4:0000:a772:00fd:a523:0358 What is IPV6Address?
Answer:
From the given address: 7d2b:00a9:a0c4:0000:a772:00fd:a523:0358
We can see that:
There are 8 groups separated by a colon.Each group is made up of 4 hexadecimal digits.In general, Internet Protocol version 6 (IPv6) is the Internet Protocol (IP) which was developed to deal with the expected anticipation of IPv4 address exhaustion.
The IPv6 addresses are in the format of a 128-bit alphanumeric string which is divided into 8 groups of four hexadecimal digits. Each group represents 16 bits.
Since the size of an IPv6 address is 128 bits, the address space has [tex]2^{128}[/tex] addresses.

Explanation:
Basically what I thought was the way was, since 2 is first, then its 1, then since 4 is second, it's added second, lastly to get the last oneI added them all and got 9 so that's third.
Answer:
Does not exist.
Explanation:
The answer is not in the option:
Let's analyse the code:
random.randint(2,4)
This means take in random integer numbers starting with 2 and ending with 4.
Meaning numbers : 2, 3 and 4
Next math.pow(a,2) means a× a = a2
So when we input 2 the function;
math.pow(a,2) returns an integer 4
You do same for input 3 , it returns 9.
For input 4 it returns 16.
And the result is encapsulated in the function string(). Meaning display the result as a string:
4 9 16

Write a basic program that performs simple file and mathematical operations.
a. Write a program that reads dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the find() method to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990.
b. After the program is working as above, modify the program so that it reads all dates from an input file "inputDates.txt" (an Example file is attached).
c. Modify your program further so that after parsing all dates from the input file "inputDates.txt", it writes out the correct ones into an output file called: "parsedDates.txt".
Ex: If the input is:
March 1, 1990
April 2 1995

Given the array [13, 1, 3, 2, 8, 21, 5, 1] suppose we choose the pivot to be 1 the second element in the array. Which of the following would be valid partitions?
A. 1 [1, 2, 3, 5, 8, 13, 21]
B. 1 [13, 1, 3, 2, 8, 21, 5]
C. 1 [13, 3, 2, 8, 21, 5, 1]
D. [1] 1 [13, 3, 2, 8, 21, 5]
E. [13] 1 [3, 2, 8, 21, 5, 1]
F. [13, 1, 3, 2, 8, 21, 5] 1 2/4
Answer:
D. [1] 1 [13, 3, 2, 8, 21, 5]
Explanation:
Using a quicksort with 1 as the pivot point, elements less than 1 will be sorted to the left of 1 and the other elements are greater than one will be sorted to the right of 1. The order doesn't matter. So we sort [1] to the left of 1 and [13, 3, 2, 8, 21, 5] to the right of 1. So, D. [1] 1 [13, 3, 2, 8, 21, 5] is the valid partition.

Federal, state, and local taxes add a total of 12% to each billThe company wants a program that will accept customer's name and the number of text messages sent. The program should display the customer's name and the total end of the month bill before and after taxes are added.
Answer:
The pseudocode is as given below in the explanation while the flow diagram is attached herewith
Explanation:
The pseudocode is as follows
input cust_name, num_texts
Set Main_bill=5 $;
if the num_texts is less than or equal to 60
Excess_Charge=0;
If the num_texts is greater than 60 and less than or equal to 200
num_text60200 =num_texts-60;
Excess_Charge=0.1*(num_text60200);
else If the num_texts is greater than 60
num_texts200 =num_texts-200;
Excess_Charge=0.25*(num_texts200)+0.1*(200-60);
Display cust_Name
Total_Bill=Main_bill+Excess_Charge;
Total_Bill_after_Tax=Total_Bill*1.12;
Write a program that displays the following pattern: ..\.\* .\.\*** \.\***** ******* \.\***** .\.\*** ..\.\* That is, seven lines of output as follows: The first consists of 3 spaces followed by a star. The second line consists of 2 spaces followed by a 3 stars. The third consists of one space followed by 5 stars, and the fourth consists just of 7 stars. The fifth line is identical to third, the sixth to the second and the seventh to the first. Your program class should be called StarPattern
Answer:
public class StarPattern {
public static final int MAX_ROWS = 7;
public static void main(String []args){
for (int row = 1; row <= MAX_ROWS; row++) {
int numOfSpaces = getNumberOfSpaces(row);
int numOfStars = MAX_ROWS - (getNumberOfSpaces(row) * 2);
String spaces = printSpaces(numOfSpaces);
String stars = printStars(numOfStars);
System.out.println(spaces + stars);
}
}
public static int getNumberOfSpaces(int row) {
int rowOffset = (MAX_ROWS / 2) + 1;
return Math.abs(row-rowOffset);
}
public static String printSpaces(int num) {
String result = "";
for (int i = 0; i < num; i++) {
result += " ";
}
return result;
}
public static String printStars(int num) {
String result = "";
for (int i = 0; i < num; i++) {
result += "*";
}
return result;
}
}
Explanation:
So it sounds we need to make a diamond shape out of asterisks like this:
*
***
*****
*******
*****
***
*
There are 7 rows and each row has up to 7 characters. The pattern is also symmetrical which makes it easier. Before writing any code, let's figure out how we are going to determine the correct amount of spaces we need to print. There are a lot of ways to do this, but I'll just show one. Let's call the 4th row y=0. Above that we have row 3 which would be y=-1, and below is row 5 which is y=1. With 7 rows, we have y=-3 through y=3. The absolute value of the y value is how many spaces we need.
To determine the number of stars, we just double the number of spaces, then subtract this number from 7. This is because we can imagine that the same amount of spaces that are printed in front of the stars are also after the stars. We don't actually have to print the second set of spaces since it is just white space, but the maximum number of characters in a row is 7, and this formula will always make sure we have 7.
I hope this helps. If you need help understanding any part of the code, jsut let me know.
