Data set A have a median of 2, mean of 3.4, min of 1 and max of 9. range of 8
Data set B have a median of 7, mean of 6, min of 1 and max of 12, range of 11
so Data set B is much bigger than data set A
Answer:
2nd is the correct answer for your question
<h2>
Half Life</h2>
The half life period is the time in which only half of the given population remains. It can be represented through this equation:
![f(t)=a\times(1/2)^{\frac{t}{h}}](https://tex.z-dn.net/?f=f%28t%29%3Da%5Ctimes%281%2F2%29%5E%7B%5Cfrac%7Bt%7D%7Bh%7D%7D)
- <em>t</em> = time passed
- <em>a</em> = y-intercept
- <em>h</em> = half life
<h2>Solving the Question</h2>
We're given:
- <em>h</em> = 28 million years
- <em>a</em> = 184 grams (this is the initial mass, after 0 time has passed)
For most questions like this, we would have to plug these values into the equation mentioned above. However, this question asks for the time elapsed after 3 half-lives.
This can be calculated simply by multiplying the given half-life by 3:
28 million years x 3
= 84 million years
<h2>Answer</h2>
84 million years
25hr. 40h. 10hr
375$ 600$ x
25 . 40 . x = 1000
375 . 600 = 225000
225000÷1000
x = 225
