There's ambiguity here. Either the original expression is "5 times the square root of a" or 5 is the "index of the root."
Then "5 times square root of a" would be 5a^(1/2), or
1/2
5a
. On the other hand, if you meant 5 to be the "index of the root," then the correct result would be
1/5
a

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
I’m pretty sure it is at 3 seconds because that is the only other time it hits 20. Hope this helps!
60 because every x number equals 60 y numbers also if you divide the last x number which is 4 by the last y number that is 240 you get 60
