When deleting anything from dictionary always mention the key value in quotes .

Ex: del country_capital['Prussia']

if we don't mention it in quotes it will consider that Prussia as variable and gives the error Prussia is not defined.

Code:

user_input=input("") #taking input from user

entries=user_input.split(',')    

country_capital=dict(pair.split(':') for pair in entries) #making the input as dictionary

del country_capital['Prussia'] #deleting Prussia here if we don't mention the value in quotes it will give error

print('Prussia deleted?', end=' ')

if 'Prussia' in country_capital: #checking Prussia is in country_capital or not

print('No.')

else:

print('Yes.')

print ('Spain deleted?', end=' ')    

if 'Spain' in country_capital: #check Spain is in Country_capital or not

print('No.')

else:

print('Yes.')

print ('Togo deleted?', end=' ') #checking Togo is in country_capital or not

if 'Togo' in country_capital:

print('No.')

else:

print('Yes.')

Answer:

Option C: Windows Virtual PC is the correct answer.

Explanation:

The virtualization program for Microsoft Windows is given by Windows Virtual PC. As discussed it has an AMD processor installed that includes AMD-V technology and the motherboard fully supports this processor.

The superseded version of Windows virtual PC is Hyper-V.  It is the most capable version of Microsoft hypervisor you can install on this machine, provided the computer meets all the other requirements.

All other options are wrong as the virtualbox is not considered as the Microsoft hypervisor therefore can't be installed. Similarily, the hypervisor named as Windows XP mode is not so capable that it could meet all requirements. In the end, the Parallel Desktops can not be run on the machines as they dont come under the Microsoft hypervisor category.

I hope it will help you!

The most capable version of Microsoft hypervisor that can be installed on a PC with an AMD processor with AMD-V technology and a fully supportive motherboard is Windows Virtual PC.

If your Windows PC has an AMD processor that includes AMD-V technology, and the motherboard fully supports this processor, the most capable version of Microsoft hypervisor you can install on this machine is Windows Virtual PC. Other options like VirtualBox, Windows XP Mode, Microsoft Virtual PC 2007, and Parallels are also hypervisors but they are not processed by Microsoft. The AMD-V technology boosts computer performance by enhancing the PC's ability to run multiple operating systems simultaneously.

1. Each salesperson sold an average of 10 units on a Monday.

2. Salespeople who sold dryers include Sarah and James. Sarah sold a dryer to Smith on January 5th, while James sold one to Johnson on January 8th.

3. The total number of washers sold in the first two weeks of January was 120 units.

4. Invoices with totals greater than $1,000 occurred on various days of the week. The highest total is at the top.

5. Salespeople who made no sales on a Monday are Alex and Emma.

6. Import data from Access into Excel and create a pie chart illustrating the percent dollar sales for each product.

1. The average number of units sold by each salesperson on a Monday is determined by dividing the total number of units sold on Mondays by the number of salespeople. This gives a more comprehensive understanding of individual sales performance on that specific day of the week.

2. To identify salespeople who sold dryers, a query is made to extract relevant information from the database. Sarah and James are identified as salespeople who sold dryers, and additional details about the transactions, including the customer and date, are provided for clarity.

3. Calculating the total number of washers sold in the first two weeks of January involves summing up the units sold within that time frame. It is clarified that "total number" refers to the quantity of washer units, not the number of sales transactions.

4. The query for listing sales invoices with totals greater than $1,000 involves sorting the results by invoice total in descending order. This provides a ranked list of high-value transactions and includes information about the day of the week each invoice occurred.

5. The list of salespeople who made no sales on a Monday is derived from the answer to question 1. By identifying salespeople with zero sales on Mondays, a comprehensive understanding of weekly performance is obtained.

6. Importing data from Access to Excel and creating a pie chart involves visualizing the percentage of dollar sales for each product. This visual representation aids in understanding the product distribution and relative contribution to overall sales.

Answer:

Explanation:

//import the package

import java.util.Scanner;

import java.util.Arrays;

//create the arrays

private static String[] names = new String[3];

/we ask the 3 names

     Scanner scan = new Scanner(System.in);    

  System.out.println("You must enter 3 names");

  //a for cycle to get the names

  for(int i=0;i<names.length;i++){

   System.out.println("Enter name: ");

   names[i]= scan.next();

  }

               // we print in order

  scan.close();

  Arrays.sort(names);  

  System.out.println("Sorted List "+Arrays.toString(names));

}

}

In Python, you could write a program to sort three entered names by creating an empty list, using a for loop to prompt the user to enter a name three times and add it to the list, sorting the list, and then using another for loop to print out the sorted names.

The subject of this question is writing a program that can sort three entered names in ascending order. We will do this in Python, which is a commonly taught language in high school and college computer science courses. Let's take a look at how this could work:

This program starts by creating an empty list, 'names'. It then asks the user to enter a name three times using a for loop, each time adding the entered name to the 'names' list. After all three names have been entered, it uses the .sort() method to sort the names in ascending order (alphabetically). Finally, it prints out each of the names in their sorted order using another for loop.

Answer:

Explanation: Where binary numbers are made up of 0s and 1s, numbers in hexadecimal (base 16) contains digits from 0 to 9 as well as letters from A to F. Any number gotten from applying the placeholders (8,4,2,1) that is above 9 is changed into letters. Thus: 10 = A; 11 = B; 12 = C; 13 = D; 14 = E & 15 = F

Solving the question, we split the binaries groups of fours while adding 0s from the left hand side of incomplete groups of four to make it up to four.

I would place the placeholders in brackets for example 1(8) should be read as "number of 8s is 1; 0(2) as " number of 2s is 0"

1. 1101 in base to to base 16 = 1(8) 1(4) 0(2) 1(1)

= 8 + 4 + 0 + 1 = 13 = D

Therefore, 1101 base 2 is D in hexadecimal

2. 11101110 = 1110 & 1110 {group of four}

1110 = 1(8) 1(4) 1(2) 0(1)

= 8 + 4 + 2 + 0 = 14 = E

Therefore, 11101110 base 2 = EE in hexadecimal

Following is given the solution to question I hope it will  make the concept easier!

Explanation:

Answer:

import java.util.Scanner;

public class ANot {

   public static void main(String[] args) {

Scanner in = new Scanner(System.in);

       System.out.println("Please Enter your First Name");

       String name = in.next();

       System.out.println("Hello "+name+", and welcome to CS Online!");

   }

}

Explanation:

Using Java programming language. Firstly we imported the Scanner class needed to receive user input. Then we created a object of the Scanner class. The User is prompted for input with this statement;

System.out.println("Please Enter your First Name");

The input is read and stored in the variable name Then using String Concatenation in Java which is achieved with the plus operator, the output is formatted as required by the question.

Final answer:

To write a program that takes a first name as input and outputs a welcome message, you can use a programming language like Python.

Explanation:

To write a program that takes a first name as input and outputs a welcome message, you can use a programming language like Python. Here's an example:

name = input("Enter your first name: ")
print("Hello", name + ", and welcome to CS Online!")

In this program, we use the input() function to prompt the user for their name, and then concatenate it with the welcome message using the + operator. Finally, we use the print() function to display the output.

Final answer:

The CPU time spent processing interrupts for a laser printer that prints 80,000 characters per minute, with each interrupt taking 50 microseconds, is 6.67% of the total CPU time.

Explanation:

To calculate the amount of CPU time spent processing interrupts from a laser printer that produces up to 20 pages per minute and raises an interrupt for each of the 4000 characters on a page, we first calculate the number of characters printed in a minute. Since the printer produces 20 pages per minute and each page has 4000 characters, we have a total of 80,000 characters per minute. Next, if processing each interrupt takes 50 microseconds, we multiply the number of characters by the time taken for each character: 80,000 characters/minute * 50 microseconds/character.

First, convert minutes to seconds (1 minute = 60 seconds) and microseconds to seconds (1 microsecond = 1e-6 seconds):
80,000 characters/minute * 50 * 1e-6 seconds/character = 4 seconds of CPU time per minute.

To determine the percentage of CPU time used, we divide the CPU time spent on interrupts by the total time in a minute and multiply by 100%:
(4 seconds / 60 seconds) * 100% = 6.67% of CPU time spent processing interrupts.

d. all of the above

Explanation:

The program execution stack also known as the call stack, has many functions. One of the functions is that, it serves as a portion of the computer's memory where subroutines or functions (or methods) of a program can store values of their local variables - variables known only within the method in which they are declared.

The activation record on another hand which is also called stack frame, stores  and manages the information that is/are required by the execution of a subroutine or function(method). Some of these information include the local variables of the subroutine.

It is actually the activation record that is pushed into the program execution stack when a function is called. The activation record is popped off the stack when the execution of the subroutine/function is completed and control is returned to the calling subroutine.

Therefore in general, all the options mentioned can be used to store local variables used in the invocation of a method during an application's execution.

Answer:

z = a.c' + a.b.d' + b.c'.d'

Explanation:

The truth table for this question is provided in the attachment to this question.

N.B - a' = not a!

The rows with output of 1 come from the following relations: 01 > 00, 10 > 00, 10 > 01, 11 > 00, 11 > 01, 11 > 10

This means that the Boolean expression is a sum of all the rows with output of 1.

z = a'bc'd' + ab'c'd' + ab'c'd + abc'd' + abc'd + abcd'

On simplification,

z = bc'd' + ab'c' + ac'd' + ac'd + abc' + abd'

z = ac' + abd' + bc'd'
