Answer:

752.71 kilobytes

Explanation:

Given ;

956-pixel x 1290-pixel

Shades of gray, = 32

Bit depth (n) = 2^n

32 = 2^5

Bit depth, n = 5 bits / pixel

The size of display memory :

Pixel dimension * n

(956 Pixel * 1290 pixel) * 5 bits /pixel

= 6166200 pixel * bits / pixel

= 6166200 bits

Converting bits to kilobytes :

1 bit = 1/8 bytes

1 byte = 1/1024 kilobytes

Hence,

1 bit = 1/(8 * 1024) kilobytes

1 bit = 1/8192 kilobytes

6166200 bits = (1/8192 * 6166200) kilobytes

= 752.7099609375 kilobytes

= 752.71 kilobytes

How to do this PLEASE HELP 80 points!
sp2606 [1]

When reading the story, you know that the code has been created by humans, so it might actually be english and use concepts like our number system, our computer code system (I'm thinking ASCII), things that you should not assume when decoding a real alien message.

Looking at the numbers I notice that digits 6 to 9 do not occur in the message, which is statistically unexpected. This leads me to believe the number base might be 6 rather than our common base 10. In the story there are insects mentioned. Insects have 6 legs, so this makes sense (after all, our base 10 was based on the number of fingers).

Next, I notice the code 052 appearing regularly, so that could be a space. Let's check a hypothesis. 052 in base 6 is 5*6+2 = 32. 32 is the ASCII code for a space!!

Now, a decoding algorithm is ready to be devised:

"for each number in the sequence, parse it as a base-6 number and then print out its corresponding ASCII value".

The following node.js snippet does this:

var code = ['220','241','255','245','052','313',

           '311','052','312','303','052','312',

           '252','245','052','205','241','251',

           '253','243','052','203','253','302',

           '251','244','303','301','053'];

           

var msg = "";

for (let n of code) {

   msg += String.fromCharCode(parseInt(n,6));

}

console.log(msg);


And the message is.........:

<em>Take us to the Magic Kingdom!</em>

So, do these aliens want to visit Disneyland????

Write an expression that will cause "greater or equal to -10" to print if the value of userNum is greater than or equal to -10.
Lilit [14]

Answer:

Expression for the above problem in python language:

userNum=int(input("Enter the value of user_Num")) #it is used to take input.

if(userNum>(-10)): #if statement

   print("The value of the userNum is greator")

elif(userNum==(-10)): #elif statement

   print("The value of the userNum is equal to -10")

else: #else statement.

   print("The value of the userNum is small")

Output:

  • If the user input is (-10), it will print equal.
  • If the user input 10, it will print greator message.

Explanation:

  • The above program or expression is in python language, where the first line is used to render a message to the user take the input and store it into a userNUM variable.
  • Then the second line is used to check the user num value to be greater with the help of if statement.
  • Then the third statement is used to check the user num value to be equal with the help of elif statement.
  • Then the else statement will execute when the if and the elif statement will not true.
