Answer:
The java program is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
Random r = new Random();
int x, y;
x = input.nextInt();
y = input.nextInt();
int[][] Array2D = new int[x][y];
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ Array2D[i][j] = r.nextInt(9) + 1; }
}
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
for(int i = 0; i < x ; i++){
for(int j = 1; j < y; j+=2){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
}
}
Explanation:
This creates a random object
Random r = new Random();
This declares x and y as integers
int x, y;
This gets input for x
x = input.nextInt();
This gets input for y
y = input.nextInt();
This declares the 2D array
int[][] Array2D = new int[x][y];
The following iteration populates the array with integers 1 to 9
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ Array2D[i][j] = r.nextInt(9) + 1; }
}
The following iteration prints all elements of the array
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
The following iteration prints all elements on the even column
for(int i = 0; i < x ; i++){
for(int j = 1; j < y; j+=2){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
Six months after a new version of an OS was released to the market, end users began to lose access to application updates. Which of the following was MOST likely the reason for this issue?A. Update limitationsB. Limited accessC. End-of-lifeD. Network connection

Given 4 floating-point numbers. Use a string formatting expression with conversion specifiers to output their product and their average as integers (rounded), then as floating-point numbers. Output each rounded integer using the following: print('{:.0f}'.format(your_value)) Output each floating-point value with three digits after the decimal point, which can be achieved as follows: print('{:.3f}'.format(your_value))
Answer:
The program is as follows:
prod = 1
isum = 0
for i in range(4):
num = float(input())
prod*=num
isum+=num
avg = isum/4
print('{:.0f}'.format(prod))
print('{:.3f}'.format(avg))
Explanation:
This initializes the product to 1
prod = 1
..... and sum to 0
isum = 0
The following iteration is repeated 4 times
for i in range(4):
Get input for each number
num = float(input())
Calculate the product
prod*=num
Add up the numbers
isum+=num
This calculates the average
avg = isum/4
Print the products
print('{:.0f}'.format(prod))
Print the average
print('{:.3f}'.format(avg))
A company is considering making a new product. They estimate the probability that the new product will be successful is 0.75. If it is successful it would generate $240,000 in revenue. If it is not successful, it would not generate any revenue. The cost to develop the product is $196,000. Use the profit (revenue − cost) and expected value to decide whether the company should make this new product.
Answer:
-16000
Explanation:
Given
P(success) = 0.75
Amount generated on success, X = 240000
P(not successful) = P(success)' = 1 - 0.75 = 0.25
Revenue generated, 0
Product development cost = 196000
Profit = Revenue - cost
When successful ; 240000 - 196000 = 44000
Unsuccessful ; 0 - 196000 = - 196000
x __________ 44000 _____ - 196000
P(x) _________ 0.75 _________ 0.25
The expected value ; E(X) = Σx * p(x)
Σx * p(x) = (44000 * 0.75) + (-196000 * 0.25)
= 33000 + - 49000
= - 16000
Hence, the company should not make the product
Answer:
-16000
Given P(success) = 0.75
Amount generated on success, X = 240000
P(not successful) = P(success)' = 1 - 0.75 = 0.25
Revenue generated, 0
Product development cost = 196000
Profit = Revenue - cost
When successful ; 240000 - 196000 = 44000
Unsuccessful ; 0 - 196000 = - 196000
x __________ 44000 _____ - 196000
P(x) _________ 0.75 _________ 0.25
The expected value ; E(X) = Σx * p(x) Σx * p(x) = (44000 * 0.75) + (-196000 * 0.25) = 33000 + - 49000 = - 16000 Hence, the company should not make the product

Write a method that prints on the screen a message stating whether 2 circles touch each other, do not touch each other or intersect. The method accepts the coordinates of the center of the first circle and its radius, and the coordinates of the center of the second circle and its radius.
The header of the method is as follows:
public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2)
Hint:
Distance between centers C1 and C2 is calculated as follows:
d = Math.sqrt((x1 - x2)2 + (y1 - y2)2).
There are three conditions that arise:
1. If d == r1 + r2
Circles touch each other.
2. If d > r1 + r2
Circles do not touch each other.
3. If d < r1 + r2
Circles intersect.
Answer:
The method is as follows:
public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){
double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));
if(d == r1 + r2){
System.out.print("The circles touch each other"); }
else if(d > r1 + r2){
System.out.print("The circles do not touch each other"); }
else{
System.out.print("The circles intersect"); }
}
Explanation:
This defines the method
public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){
This calculate the distance
double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));
If the distance equals the sum of both radii, then the circles touch one another
if(d == r1 + r2){
System.out.print("The circles touch each other"); }
If the distance is greater than the sum of both radii, then the circles do not touch one another
else if(d > r1 + r2){
System.out.print("The circles do not touch each other"); }
If the distance is less than the sum of both radii, then the circles intersect
else{
System.out.print("The circles intersect"); }

Isaac Newton devised a clever method to casily approximate the square root of a number without having
to use a calculator that has the square root function. Describe this method with illustration
Answer:
The illustration in Java is as follows:
import java.util.*;
import java.lang.Math.*;
class Main{
public static void main (String[] args){
Scanner input = new Scanner(System.in);
double num, root, temp;
num = input.nextDouble();
temp = num;
while (true){
root = 0.5 * ( (num / temp)+temp);
if (Math.abs(root - temp) < 0.00001){
break; }
temp = root; }
System.out.println("Root: "+root);
}}
Explanation:
This declares all necessary variables
double num, root, temp;
This gets input for num (i.e the number whose square root is to be calculated)
num = input.nextDouble();
This saves the input number to temp
temp = num;
This loop is repeated until it is exited from within the loop
while (true){
Calculate temporary square root
root = 0.5 * ( (num / temp)+temp);
The loop is exited, if the absolute difference between the root and temp is less than 0.00001
if (Math.abs(root - temp) < 0.00001){
break; }
Save the calculated root to temp
temp = root; }
This prints the calculated root
System.out.println("Root: "+root);
What would be the result of the flooding c++ cide assuming all necessary directive
Cout <<12345
Cout<
cout <
Cout<< number <
Answer:
See explanation
Explanation:
The code segment is not properly formatted; However, I will give a general explanation and a worked example.
In c++, setprecision are used to control the number of digits that appears after the decimal points of floating point values.
setprecision(0) means; no decimal point at all while setprecision(1) means 1 digit after the decimal point
While fixed is used to print floating point number in fixed notation.
Having said that:
Assume the code segment is as follows:
number = 12.345;
cout<<fixed;
cout<<setprecision(0);
cout<<number <<endl;
The output will be 12 because setprecision(0) implies no decimal at all; So the number will be rounded up immediately after the decimal point

Answer:
In half duplex mode, the signal is sent in both directions, but one at a time. In full duplex mode, the signal is sent in both directions at the same time. In simplex mode, only one device can transmit the signal. In half duplex mode, both devices can transmit the signal, but one at a time.
Determine whether or not the following pairs of predicates are unifiable. If they are, give the most-general unifier and show the result of applying the substitution to each predicate. If they are not unifiable, indicate why. Assume that x, y, and z are variables, while other symbols are either predicates, constants, or functions.
a) P(B,A,B), P(x,y,z)
b) P(x,x), Q(A,A)
c) Older(Father(y),y), Older(Father(x),John).
d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B)
e) P(f(x), x, g(x)), P(f(y), A, z)
Answer:
a) P(B,A,B), P(x,y,z)
=> P(B,A,B) , P(B,A,B}
Hence, most general unifier = {x/B , y/A , z/B }.
b. P(x,x), Q(A,A)
No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q.
c. Older(Father(y),y), Older(Father(x),John)
Thus , mgu ={ y/x , x/John }.
d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))
=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))
This is not unifiable as x cannot be bound for both A and B.
e) P(f(x), x, g(x)), P(f(y), A, z)
=> P(f(A), A, g(A)), P(f(A), A, g(A))
Thus , mgu = {x/y, z/y , y/A }.
Explanation:
Unification: Any substitution that makes two expressions equal is called a unifier.
a) P(B,A,B), P(x,y,z)
Use { x/B}
=> P(B,A,B) , P(B,y,z)
Now use {y/A}
=> P(B,A,B) , P(B,A,z)
Now, use {z/B}
=> P(B,A,B) , P(B,A,B}
Hence, most general unifier = {x/B , y/A , z/B }
b. P(x,x), Q(A,A)
No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q
c. Older(Father(y),y), Older(Father(x),John)
Use {y/x}
=> Older(Father(x),x), Older(Father(x),John)
Now use { x/John }
=> Older(Father(John), John), Older(Father(John), John)
Thus , mgu ={ y/x , x/John }
d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))
Use { y/x }
=> Q(G(x,z),G(z,x)), Q(G(x,x),G(A,B))
Use {z/x}
=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))
This is not unifiable as x cannot be bound for both A and B
e) P(f(x), x, g(x)), P(f(y), A, z)
Use {x/y}
=> P(f(y), y, g(y)), P(f(y), A, z)
Now use {z/g(y)}
P(f(y), y, g(y)), P(f(y), A, g(y))
Now use {y/A}
=> P(f(A), A, g(A)), P(f(A), A, g(A))
Thus , mgu = {x/y, z/y , y/A }.

Answer:
The program in python is as follows:
a = int(input("A: "))
b = int(input("B: "))
if a != 0:
a= 1
if b != 0:
b = 1
print("A AND B",end =" ")
if a == b == 1:
print("True")
else:
print("False")
print("A NAND B",end =" ")
if a == 0 or b == 0:
print("True")
else:
print("False")
print("A OR B",end =" ")
if a == 1 or b == 1:
print("True")
else:
print("False")
print("A NOR B",end =" ")
if a == 1 or b == 1:
print("False")
else:
print("True")
print("A XOR B",end =" ")
if a != b:
print("True")
else:
print("False")
print("A XNOR b",end =" ")
if a == b:
print("True")
else:
print("False")
print("NOT A",end =" ")
if a == 1:
print("False")
else:
print("True")
print("NOT B",end =" ")
if b == 1:
print("False")
else:
print("True")
Explanation:
These get inputs for A and B
a = int(input("A: "))
b = int(input("B: "))
a and b are set to 1 for all inputs other than 0
if a != 0:
a= 1
if b != 0:
b = 1
This prints the AND header
print("A AND B",end =" ")
AND is true if only A and B are 1
if a == b == 1:
print("True")
else:
print("False")
This prints the NAND header
print("A NAND B",end =" ")
NAND is true if one of A or B is 0
if a == 0 or b == 0:
print("True")
else:
print("False")
This prints the OR header
print("A OR B",end =" ")
OR is true if one of A or B is 1
if a == 1 or b == 1:
print("True")
else:
print("False")
This prints the NOR header
print("A NOR B",end =" ")
NOR is false if one of A or B is 1
if a == 1 or b == 1:
print("False")
else:
print("True")
This prints the XOR header
print("A XOR B",end =" ")
XOR is true if A and B are not equal
if a != b:
print("True")
else:
print("False")
This prints the XNOR header
print("A XNOR b",end =" ")
XNOR is true if a equals b
if a == b:
print("True")
else:
print("False")
This prints NOT header for A
print("NOT A",end =" ")
This prints the opposite of the input
if a == 1:
print("False")
else:
print("True")
This prints NOT header for B
print("NOT B",end =" ")
This prints the opposite of the input
if b == 1:
print("False")
else:
print("True")

Regarding the role played by the “victim” in deadlock resolution, give an example of such a deadlock in real life and explain your answers to these questions.
a. Describe how you might choose the victim to be removed and the consequences, both positive and negative, of that removal.
b. Describe the fate of the victim and the chances of eventually completing its processing.
c. Describe the actions required, if any, to complete the victim’s tasks.
Answer:
Here the answer is given as follows,
Explanation:
The real-life situation of a deadlock resolution where a role is played by the victim is given as follows:
Example: An example of such a situation are often a one-way lane where the flow of traffic is merely in a method. Thus, on just one occasion, the flow of traffic can enter one direction only. Each entrance/exit gate is often considered a resource. during this case, if two cars are coming from both the entrances and that they are often considered as two tasks, then one among the cars must copy or we will say hand over its resource in order that the opposite car gets the prospect to first cross the lane or we will say the opposite task gets executed.
a) Victim: The steps which describe how a victim is chosen are given as follows :
The task which is terminated so as to interrupt things of deadlock is taken into account because of the victim.
There are often a variety of job pools that will be under a deadlock situation and therefore the victim is usually a low-priority task in order that the performance isn't affected that much and termination of this task doesn't cause any effect on the opposite jobs.
the main positive effect of selecting and terminating a victim is that things of deadlock are resolved and every one of the tasks can execute now.
The negative effect is that the task that's chosen because the victim is terminated and is executed at the previous. This whole process for choosing a victim then terminating it then restarting it again may consume some longer also.
b) An easy deadlock priority is often set. this suggests that the victim’s task or the task is often terminated so as to interrupt the deadlock and other jobs can finish executing. After this, the task which is terminated are often later restarted and every one of the tasks can then execute without a deadlock.
c) When employment gets terminated, the knowledge associated with it's stored. Are often This is often done in order that the work can be restarted again and therefore the information in it's not lost. Since the progress of the victim is stopped. Thus, the sole thanks to complete the victim’s task would be to start out it again. But before restarting the task, this must be considered that the victim’s task doesn't cause any deadlock within the system.

In this chapter, you learned that although a double and a decimal both hold floating-point numbers, a double can hold a larger value. Write a C# program named DoubleDecimalTest that declares and displays two variables—a double and a decimal. Experiment by assigning the same constant value to each variable so that the assignment to the double is legal but the assignment to the decimal is not.
Answer:
The DoubleDecimalTest class is as follows:
using System;
class DoubleDecimalTest {
static void Main() {
double doubleNum = 173737388856632566321737373676D;
decimal decimalNum = 173737388856632566321737373676M;
Console.WriteLine(doubleNum);
Console.WriteLine(decimalNum); } }
Explanation:
Required
Program to test double and decimal variables in C#
This declares and initializes double variable doubleNum
double doubleNum = 173737388856632566321737373676D;
This declares and initializes double variable decimalNum (using the same value as doubleNum)
decimal decimalNum = 173737388856632566321737373676M;
This prints doubleNum
Console.WriteLine(doubleNum);
This prints decimalNum
Console.WriteLine(decimalNum);
Unless the decimal variable is commented out or the value is reduced to a reasonable range, the program will not compile without error.

Reverse Word Order: Write a program that reverses the order of the words in a given sentence. This program requires reversing the order of the words wherein the first and last words are swapped, followed by swapping the second word with the second to last word, followed by swapping the third word and the third to last words, and so on.
Answer:
function reverseArray(arr) {
if (arr.length > 1) {
arr = [arr[arr.length-1], ...reverseArray(arr.slice(1, -1)), arr[0]]
}
return arr;
}
function reverseSentence(sentence) {
let words = reverseArray( sentence.split(" ") );
return words.join(" ");
}
console.log( reverseSentence("The quick brown fox jumps over the lazy dog's back") );
console.log( reverseSentence("one two three") );
console.log( reverseSentence("one two") );
console.log( reverseSentence("Single") );
Explanation:
This is a solution in javascript leveraging several powerful constructs in that language, such as the spread operator.
The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 1.501 g sample of BHT was combusted in an oxygen rich environment to produce 4.497 g of CO2(g) and 1.473 g of H2O(g). Insert subscripts below to appropriately display the empirical formula of BHT.
Answer:
C15H24O
Explanation:
n(C) = 4.497 g/44g/mol = 0.1022
Mass of C = 0.1022 × 12 = 1.226 g
n(H) = 1.473g/18 g/mol = 0.0823 ×2 moles = 0.165 moles
Mass of H = 0.0823 × 2 ×1 = 0.165g
Mass of O= 1.501 -(1.226 + 0.165)
Mass of O= 0.11 g
Number of moles of O = 0.11g/16g/mol = 0.0069 moles
Dividing through by the lowest ratio;
0.1022/0.0069, 0.165/0.0069, 0.0069/0.0069
15, 24, 1
Hence the formula is;
C15H24O
Answer
The formula is C1SH240
