The half-life of Pu-240 is 6,561 years.
Half life can be modeled by the function
f(x) = P(0.5)^x
P is our starting amount.
x is the number of half-lives required to equal f(x).
f(x) is the amount left after x half-lives.
9 = 27(0.5)^x
1/3 = 0.5^x
log(0.5)1/3 = x
x = 1.585
6.561 years * 1.585 half-lives = 10,399.185 years.
Answer:
People reflect the laws.
Explanation:
The people are the ones with the morals and standards, it's like Umbridge in Order of the Phoenix. If people aren't happy, it's because the laws are tight and singular and possibly indubitable. Whoever enforces them has a strict constitution of said laws. Depending on these laws, depression and hostility can become common. This is only a dark side answer to this question, there are dozens of possibilities.
The answer is; gender bias
Discrimination of women of women in society may be conscious or unconscious, subtle or obvious. This is attributed to inculcated cultural tendencies, over history, that tend to treat the female gender as inferior to the male gender.
They would mostly be in the medical field.
