Answer:

All of the above.

Explanation:

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

Hence, the operating system (OS) provides utility software designed to perform specific tasks. Some of the tasks it performs are;

A. Establishing an Internet connection.

B. Coordinating tasks between programs.

C. Configuring peripheral devices.

D. Monitoring security.

David is working in a database that organizes student exam grade information. He needs to find all students who have scored 100
kobusy [5.1K]

Answer:

David can apply filter to the data in order to show only records that meet the criteria.

Explanation:

  • Filter is a very helpful option that displays the records that you want to view, hiding rest of the unwanted records.
  • Sometimes you want to extract and view only the records that match a specific criteria instead of viewing all the records.
  • For example in the CUSTOMERS table which contains names, addresses, countries of customers. There are several customers from different countries but you only want to view the customers from Spain. So you can use filter feature to view all the customers from country Spain.
  • In MS Access you can apply filters using Sort & Filter group in the Home tab by selecting the desired column. In SQL, WHERE clause can be used along with SELECT to for filtering and extracting certain records. SELECT will select the records from the table and WHERE clause will specify the criteria to select the certain records.

#Write a function called "scramble" that accepts a string #as an argument and returns a new string. The new string #should start
mojhsa [17]

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)

Margaret [11]

Answer:

from random import randint

winner  = False

number = str(randint(10000, 99999))

while (not winner):

   correct = 0

   total = 0

   guess = input()

   

   if(number==guess):

       winner = True

   else:

       for i in range(5):

           if(number[i] == guess[i]):

               correct+=1

               total+=int(number[i])

       

       print('Correct: '+ str(correct))

       print('Total: '+ str(total))

print('Winner')

Explanation:

I´m gonna show a solution in python 3

Step 1 import library for generate random number

from random import randint

Step 2 create necesary variables to get the number and if the player is winner or not

winner  = False

number = str(randint(10000, 99999))

Step 3 loop while the player is not the winner

while (not winner):

Step 4 get the player guess number

guess = input()

Step 5 validate if the player win

if(number==guess):

       winner = True

Step 6 if the player is not winner review what numbers are  in the correct position

for i in range(5):

           if(number[i] == guess[i]):

               correct+=1

               total+=int(number[i])

Step 7 print the hint

print('Correct: '+ str(correct))

print('Total: '+ str(total))
