Answers
Answer:
In Python:
sttr = input("String: ")
ch = input("Character: ")
count = sttr.count(ch)
print(str(count)+" "+ch, end = '')
if count>1 or count==0:
print("'s")
Explanation:
This prompts the user for string
sttr = input("String: ")
This prompts the user for character
ch = input("Character: ")
This counts the number of occurrence
count = sttr.count(ch)
This prints the number of occurrence of the character
print(str(count)+" "+ch, end = '')
This checks if the number of occurrence is 0 or greater than 1.
if count>1 or count==0:
If yes, it prints 's
print("'s")

A group of pupils scored an average of 92 marks for a test. The boys scored an average of 90 marks while the girls
scored an average of 95 marks. What is the ratio of the number of boys to the number of girls in the group?
Answers
Answer: 1.5 : 1
Explanation:
The average of 92 marks for the test is a weighted average of the proportion of students in the class.
Assume boys are in the proportion, x.
(90 * x) + (95 * (1 - x)) = 92
90x + 95 - 95x = 92
-5x = 92 - 95
-5x = -3
x = -3/-5
x = 0.6
Boys are 0.6 of the class
Girls are:
= 1 - 0.6
= 0.4
0.6 : 0.4

how can u spot fake news through camerawork, audio, and lighting? pls answer asap
Answers
Answer:
Fake news usually would involve heavy editing of the audio and visuals so that what people can see or hear will fit the lies being sold.
Explanation:
With respect to Videos, fake news would usually have very subtle and intelligent cuts and joints such that when pieced together, a speech for instance would contain only the words which fit the fake news. Also. the context would usually be omitted and you'd seldom find a whole unedited video supporting fake news.
With regards to the audio, authentic sources, in most cases, usually, start a recorded audio with their signature jingle. Fake news won't.
Pictures that have been doctored to suit fake news are usually characterized by their low quality, grainy and blurry feel.
It is important to point out, however, that with advances in technology, fake news' are begining to lose most of the qualities listed above.

Give a regular expression for binary numbers. They can be integers or binary fractions. A leading - sign is always allowed. Leading 0's are not allowed except when the integer part is 0. When the binary points is present, then neither the integer part nor the fractional part are allowed to be empty. If the integer part has more than 3 bits, then grouping with commas is required. Examples: Allowed: -0 1,111,010 -1,111.00 Not allowed: .11 1000 The 4-letter alphabet consists of 0, 1, dot, and comma.
Answers
Solution :
We have to provide an expression for the binary numbers. There can be binary fractions or integers. Whenever there is leading 0, it is not allowed unless the integer part is a 0.
Thus the expression is :
[tex]$(-+ \in )$[/tex] [tex]$[(1+10+11+100+101+110+111)(,000+,001+,010+,011+,111+,100+,101+,110)^*$[/tex] [tex]$(\in +.(0+1)^*(0+1))+(0.(0+1)^*(0+1))]$[/tex]
In this exercise we have to have knowledge about binary code to calculate with these numbers, so we have:
[tex](E+(0+1)*(0+1))[/tex]
What is a binary code?A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system.
Knowing this now we can perform the calculations like:
[tex](1+10+11+100+101+110+111)(000+001+010+011+111+100+101+110)\\(E+(0+1)*(0+1))[/tex]

In an ancient land, the beautiful princess Eve (or handsome prince Val) had many suitors. Being royalty, it was decided that a special process must be used to determine which suitor would win the hand of the prince/princess. First, all of the suitors would be lined up one after the other and assigned numbers. The first suitor would be number 1, the second number 2, and so on up to the last suitor, number n. Starting at 4 the suitor in the first position, she/he would then count three suitors down the line (because of the three letters in his/her name) and that suitor would be eliminated and removed from the line. The prince/princess would then continue, counting three more suitors, and eliminate every third suitor. When the end of the line is reached, counting would continue from the beginning. For example, if there were 6 suitors, the elimination process would proceed as follows:_____.
12456 Suitor 3 eliminated; continue counting from 4.
1245 Suitor 6 eliminated; continue counting from 1.
125 Suitor 4 eliminated; continue counting from 5.
15 Suitor 2 eliminated; continue counting from 5.
1 Suitor 5 eliminated; 1 is the lucky winner.
Write a program that creates a circular linked list of nodes to determine which position you should stand in to marry the princess if there are n suitors. Your program should simulate the elimination process by deleting the node that corresponds to the suitor that is eliminated for each step in the process.

Explanation:
The given statement is true, that an if statement must always begin with the word “if.” in python.
What is the python?A high-level, all-purpose programming language is Python. Code readability is prioritized in its design philosophy, which makes heavy use of indentation. Python uses garbage collection and has dynamic typing.
It supports a variety of paradigms for programming, including functional, object-oriented, and structured programming. An “if” statement must always be the first word in a sentence.
One of the most often used conditional statements in computer languages is the if statement in Python. It determines whether or not particular statements must be performed. It verifies a specified condition; if it is true, the set of code included within the “if” block will be run; if not, it will not.
