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
1.5 : 1

Assume that the execution time for a program is directly proportional to instruction access time. The access to an instruction in the cache is 10 times faster than access to an instruction in the main memory. If an instruction is not found in the cache, i.e., cache miss, it is fetched from the main memory to the cache and then fetched from the cache to be executed. Assume that a requested instruction will cause cache miss has a probability of 0.08. Let the speedup factor is defined as the ratio of program execution time without the cache to program execution time with the cache.
a. Calculate the speedup factor to execute such a program.
b. using this assumption, assuming that the cache is 20 times faster than the main memory.
Answer:
a. 5.81
B. 7.93
Explanation:
A.
X is the time it takes to load instructions from cache
10X = time to execute program
0.08 = probability of cache instructions
1-0.08 = 0.92(92% instructions are going to be loaded from cache).
Tc = time to execute with cache
Tc = 0.92X+0.08x10X
= 0.92X+0.8X
= 1.72X
Speed factor = tm/tc
= 10X/1.72X
= 5.81
B.
If cache is 20 times faster
Tm = 20X
Tc = 0.92X + 0.08 x 20X
= 0.92X + 1.6X
= 2.52X
Speed factor = 20X/2.52X
= 7.93

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.
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]

what is this a question or just saying something?
Explanation:
Answer:
uh what?
Explanation:
Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them. The formula for computing the distance is: Square root of ((x2 - x1) squared + (y2 - y1) squared) Note that you can use pow(a, 0.5) to compute square root of a.
Answer:
x1 = input("enter x value of first number: ")
y1 = input("enter y value of first number: ")
x2 = input("enter x value of second number: ")
y2 = input("enter y value of second number: ")
ans = (float(x2)-float(x1))**2 + (float(y2)-float(y1))**2
ans = pow(ans, 0.5)
print(ans)

An if statement must always begin with the word “if.” True False python
Answer:
true
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.
Therefore, it is true.

write a paragraph in python to print 5 using a for loop
Answer:
For f in range(10):

The for loop initiates a range of value and f is used to evaluate each value in the range.
The if statement block checks and detect if the number in the range, f is 5 ; once it detect that f equals to 5, it prints the digit 5 using the print statement.
how can u spot fake news through camerawork, audio, and lighting? pls answer asap
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.

4.16 LAB: Count characters Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. Ex: If the input is: n Monday the output is: 1 n Ex: If the input is: z Today is Monday the output is: 0 z's Ex: If the input is: n It's a sunny day the output is: 2 n's Case matters. Ex: If the input is: n Nobody the output is: 0 n's
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")
