Today when Dylan turned on his computer, he noticed that the monitor was very dim. He could still see the desktop icon and text.

He turned the brightness all the way up, but that did not correct the issue. Dylan also checked to make sure the Power Options brightness was not turned down, causing the screen to go dim. He connected a different monitor, and the screen was fine. What caused the screen to be very dim

Answer:

The Liquid Crystal Display lighting of the monitor is most likely faulty.

Explanation:

By connecting his computer to an external monitor and observing that the brightness of the external monitor was fine, we can deduce that the dimness of his computer was not a software issue but that of hardware. That is the computer monitor itself.  

The most probable reason for the dimness of his computer monitor would e an hardware issue occasioned by a faulty LCD - Liquid Crystal Display or LED, the back light powering the LCD of his computer computer monitor would have to be replaced by a qualified technician.

How many bit strings of length 12 contain the substring 111000?
ELEN [110]

Answer:

448 strings

Explanation:

Each bit string can be filled by two ways either 0 or 1. If the bit strings of length contain the substring '111000' we therefore need a substring of length 6.

The selection of bits starts from the 1st bit to 7th bit enclosing the substring 111000 and ensuring that the length 6 are all filled. So, there will be  7 ways to contain this substring.

The total ways to contain this substring = 7*2^6 =448

Therefore 448 strings of length 12 contain the substring '111000'.

Write a program that receives a series of numbers from the user and allows the user to press the enter key to indicate that he o
Dmitriy789 [7]

Answer:

The solution code is written in Python 3

  1. count = 0
  2. sum = 0
  3. num = input("Enter a number: ")
  4. while(num != ''):
  5.    sum += float(num)
  6.    count += 1
  7.    num = input("Enter a number: ")
  8. print("Sum : " + str(sum))
  9. print("Average: " + str(sum / count))

Explanation:

Firstly, we declare two variables count and sum to hold the number of input number and the total of the input number, respectively (Line 1-2)

Next, we prompt user to input the first number (Line 4). While the num is not ' ' (This means it is not "Enter" key), accumulate the num to sum variable and increment count by one (Line 6-8) and then prompt the user to input the next number (Line 9).

At the end, display the sum and average using print function (Line 11 -12).

Use python
konstantin123 [22]

Answer:

Here is the Python program:

def exec_2(f):

    f()

    f()

   

def exec_4(f):

    exec_2(f)

    exec_2(f)

   

def print_koala():

    print("koala")    

exec_4(print_koala)

Explanation:

The program works as follows:

First method:

def exec_2(f):

f()

f()

any function that is passed into exec_2() will be executed twice without parameters.

Second method:

def exec_4(f):

    exec_2(f)

    exec_2(f)

function exec_4(f) takes in a function f as a parameter and executes the function f 4 times using the function exec_2. At first exec_2(f) call the function f is executed twice and and second exec_2(f) call the function f is again executed twice so the function f executes 4 times in total.

Third method:

def print_koala():

    print("koala")  

a function that prints out the koala once

This function has a print statement which is passed the string koala to print on output screen.

exec_4(print_koala)

function exec_4 is used to print koala four times. This function exec_4 takes as argument the function print_koala() So this works as follows:

exec_4(print_koala)

The body of exec_4 executes as:

exec_2(print_koala)

exec_2(print_koala)

Now at first call to exec_2(print_koala) the program moves to the function exec_2 which executes print_koala()  method twice. Since print_koala() method has a print statement print("koala") so this is executed twice:

koala                                                                                                                                           koala

Now at second call exec_2(print_koala) the program moves to the function exec_2 which executes print_koala()  method twice again. Since print_koala() method has a print statement print("koala") so this is executed again twice:

koala                                                                                                                                           koala

So the output of the entire above program is:

koala                                                                                                                                           koala                                                                                                                                           koala                                                                                                                                           koala

The screenshot of program along with its output is attached.
