I’m pretty sure it’s D??? But it also could be B I’m sorry :( trying to help as much as possible
Answer:
We can divide both sides by 20 and we got:
Now we can appply natural log on both sides and we got:
Now we can divide both sides of the equation by 10 and we got:
So then the aproximate value of k is 0.30986 and rounded would be 0.31
Step-by-step explanation:
We have the following two expression:
We know that the two populations were equal 10 years after the start of the study, so then we can create the following equation:
We can divide both sides by 20 and we got:
Now we can appply natural log on both sides and we got:
Now we can divide both sides of the equation by 10 and we got:
So then the aproximate value of k is 0.30986 and rounded would be 0.31
