write a program to update the rate by increasing 20% from sequential data file "items.dat" that store item name.rate and quantity​

Answer:

D

Explanation:

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))  

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.

Explanation:

Need a better discription of the question to finalize an answer.

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")

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);

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

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 }.

This is a solution in javascript leveraging several powerful constructs in that language, such as the spread operator.

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");     }

}

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
