A. Initially, only one person had heard the rumor. B. There are 299 people in the enclosed space. C. It will take approximately 14 minutes for 100 people to hear the rumor. D. The rate at which the rumor spreads speeds up over time. **choose ALL that apply!!

4. anonymous

**my answers: A and B... is that right??? are the answers just A and B??

5. anonymous

@satellite73 @jim_thompson5910 @hartnn ?? are those right?? :)

6. hartnn

A is correct, how 299 ? isn't it 300 ?

7. anonymous

yeah thats what i thought too.. but the answer choice is 299 so i guess thats the closest haha :P

8. anonymous

so are both A and B answers??

9. hartnn

no, B can't be, it has to 300, 299 is not close enough

10. anonymous

i see... so what about C and D then??

11. anonymous

so far we have just A.... what about C and D??

12. anonymous

initially means put $$t=0$$ you get $$\frac{300}{300}=1$$

13. anonymous

kk so what does that mean ?

14. hartnn

i am getting C correct, did u try C ??

15. anonymous

it means A is right D is wrong because although it speeds up at the beginning is slows down later

16. anonymous

yeah so A and C are my final answers right? cuz B and D cannot work?

17. hartnn

yes.

18. anonymous
