Assume that x and y are boolean variables and have been properly initialized.(x && y) || !(x && y) The result of evaluating the expression above is best described as (A) always true (B) always false (C) true only when x is true and y is true (D) true only when x and y have the same value (E) true only when x and y have different values

Answers

Answer 1

Answer:

(A) Always true

Explanation:

Given

Boolean variables x and y

Required

What is (x && y) || !(x && y)

Irrespective of what x or y is, the x && y is always true

Take for instance:

x = true;

y = true;

x&&y will also be true because the values of x and y were not altered

And this is true for whatever boolean value x or y assume

Having said that:

x&&y = true

So, the expression is analysed as follows:

(x && y) || !(x && y)

Substitute true for x&&y

(true) || !(true)

!(true) = false

So, the expression becomes:

true || false

|| represents the OR operator; and it returns true if at least one of the conditions is true.

By this:

true || false = true

Option (A) Always true answers the question.

Answers

Answer:

The answer is "Option 2".

Explanation:

In HTML5, text inputs use an autofocus attribute, which, when the page is loaded, uses a template to concentrate primarily on text fields. This attribute is a Boolean property that represents the HTML autofocus attribute, showing if the related <select> element will receive an output focus whenever the page loads if it is overruled by the user. An only form-associated entity can have this property specified in a text.

A certain instructor assigns a 50-point problem and calculates an integer score 0-50 and assigns a letter grade according to the scale 40 - 50 is an A, 30 - 39 is a B, 20 - 29 is a C, 10 - 19 is a D and 0 - 9 is an F. Write a Python function called letter_grade which takes one argument, an integer, and RETURNS the appropriate letter grade.

Answers

Answer:

Following are the code to this question:

def letter_grade(x): #defining a method letter_grade that accepts one parameter

   if x>=50 and x<=40:#defining if block that check value of x greater than 50 and less than 40

       print("A")#print value

   if x>=30 and x<=39:#defining if block that check value of x greater than 30 and less than 39

       print("B")#print value

   if x>=20 and x<=29:#defining if block that check value of x greater than 20 and less than 29

       print("C")#print value

   if x>=10 and x<=19:#defining if block that check value of x greater than 10 and less than 19

       print("D")#print value

   if x>=0 and x<=9:#defining if block that check value of x greater than 0 and less than 9

       print("F")#print value

letter_grade(30) #calling the method letter_grade

Output:

B

Explanation:

In the above Python code, a method "letter_grade" is declared, that accepts an integer variable in its parameter, and defined the multiple if block to check the given value, which can be defined as follows:

In the first, if block, it checks the value of x greater than 50 and less than 40 , if the condition is true it will print the value "A".In the second, if block, it checks the value of x greater than 30 and less than 39,  if the condition is true it will print the value "B".In the third, if block, it checks the value of x greater than 20 and less than 29,  if the condition is true it will print the value "C".  In the fourth, if block, it checks the value of x greater than 10 and less than 19,  if the condition is true it will print the value "D".In the fifth, if block, it checks the value of x greater than 0 and less than 9,  if the condition is true it will print the value "F".

And at the last it call the method.

What is computer virus?​

Answers

Answer:

A piece of code which is capable of copying itself and typically has a detrimental effect, such as corrupting the system or destroying data.

Explanation:

A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.

Simply, a computer virus is a harmful multiplying code that harms your computer and makes it slower, harder to use, and more vulnerable to other harmful unsafe software, apps, downloads and more.

How to get it?

You can get computer viruses just from going to unsafe websites downloading harmful files downloading harmful images downloading harmful videos clicking unsafe advertisements

and thats just a couple of examples, there's many many more but you get the idea.

Something that really sucks about computer viruses is that its hard to tell if something online is dangerous or not.

That's why people make specific softwares to protect your computer but even those can be unsafe or people could be trying to trick you.

Sometimes the computer will already have some sort of app or software to protect it from these harmful files, but make sure to pay attention when your on websites and check the urls and make sure it doesn't say anything along the lines of "unsafe" if it says that just simply exit the website and dont do anything further.

If your experiencing slowness, files you don't remember saving on your computer or extra files and apps that dont seem to belong, im sure there are places you can call online or in your local area to help with these issues.

Hope this helped!!
