Complete question is;
The probability that a comic book reader in a particular city prefers comics published by Company A is 25%. The probability that a comic book reader in the city is male is 70%. If the probability of a comic book reader in the city being a male, given that the reader prefers Company A's comics, is 40%, what is the probability of the reader preferring Company A's comics, given that the reader is a male?
Answer:
0.14 or 14%
Step-by-step explanation:
We are told that the probability that the comic book readers prefers comics published by company A is 25%.
Thus; P(A) = 25% = 0.25
Also, we are told that the probability that comic book reader is male 70%.
Thus; P(M_r) = 70% = 0.7
We are also told that the probability of a comic book reader being a male, provided that the reader prefers Company A's comics, is 40%.
Thus; P(A|M_r) = 40% = 0.4
To find the probability of the reader preferring Company A's comics, provided that the reader is a male, we will apply baye's theorem.
Thus;
P(M_r|A) = [P(A|M_r) × P(A)]/P(M)
P(M_r|A) = (0.4 × 0.25)/0.7
P(M_r|A) ≈ 0.14

Answer:
x = 9.83
Step-by-step explanation:
Taking 55 as the reference angle,
hypotenuse (h) = 12
perpendicular (p) = x
Sin 55 = p/h
Sin 55 = x / 12
x = Sin55 x 12
x = 9.83

What is the definition of homonym?
Answer:
a group of words that share the same spelling and pronunciation but have different meanings.
Answer:
If they are pronounced the same then they are also homophones (and homonyms) – for example, bark (the sound of a dog) and bark (the skin of a tree). If they are pronounced differently then they are also heteronyms – for example, bow (the front of a ship) and bow (a ranged weapon).
Derek bought his truck for $30,000. The value has dropped by $900 each year. He determined that the value of his truck (V) can be modeled by: V = 30,000 - 900x where V is the value of the truck and x is the number of years since he bought his truck.
How much will his truck be worth 10 years after he bought it?

In a race 24 out of 25 cyclists finished in less than 51 minutes what percentage of cyclists finished the race in less then 51 minutes
Answer: 96%
Step-by-step explanation:
There are 25 total cyclists and 24 of those finished the race in less than 51 minutes. The question would like this 24 to be expressed as a percentage of 25.
In percentage this would be:
= Number of cyclists who finished in 51 minutes / Total number of cyclists * 100%
= 24 / 25 * 100%
= 96%
You find a piece of wood that is 7.24 long and your friend finds one that is 4.65cm how long would they be if you attached them?
Answer:
They would be 11.89cm long.
The total length of the two pieces of wood is 11.89cm.
When two pieces of wood are found by different people,
The total length of both pieces can be calculated by adding their respective lengths.
In this case,
One person found a piece of wood that is 7.24cm long,
While the other person found a piece that is 4.65cm long.
To determine the total length of both pieces of wood,
Simply add 7.24cm and 4.65cm together.
The sum of these two measurements is,
4.65 + 7.24 = 11.89cm.
That would be the total length of the two pieces of wood if they were attached.
Therefore, if we want to attach these two pieces of wood together, we will need a length of material that is at least 11.89cm long.

oi can someone help me with this one ^{2}-12x-28=0
This is still pretty confusing for me
Answer:
Both answers should be -2 and 14.
Step-by-step explanation:
Using the quadratic formula:
[tex]x^{2}-12x-28=0\\\\x=\frac{-(-12)+-\sqrt{(-12)^2-4(1)(-28)} }{2(1)}\\\\x= \frac{12+-\sqrt{144+112} }{2}\\\\x= \frac{12+-\sqrt{256} }{2}\\\\x= \frac{12+-16 }{2}\\\\x=6+-8[/tex]
Therefore:

Em uma escola,estudam em tres periodos 1256 meninas e 1593 meninos. quantos alunos estudam nessa escola?
Answer:
I will answer in English.
This can be translated to:
In a school, 1256 girls and 1593 boys study in three periods. how many students study at that school?
This means that we have a total of:
(1256 + 1593) students = 2849 students, divided in 3 periods.
So the total number of students in that school is 2849
And the number of students per period is:
2849/3 = 949.7
Because we can only have whole numbers here, we can say that in each period there are around 950 students.
