Question 430169
The initial count (at 0) is 100. The count at 12 is 50. Since 50 is 1/2 of 100 it appears that the half-life would be 12 shakes.(What's a shake?)<br>
But then the data says that at 20 shakes the count is 25. But 25 is 1/2 of 50. So 25 should happen a half-life after 50. So it should happen aother 12 shakes later, <i>not 8 shakes later like that data shows.</i> So the data is inconsistent.
