the last one can be found using proportion
100=4
750=x
x=(750 times 4)/100

- xapproachesinfinity

hmm second i guess proportions too

- xapproachesinfinity

actually the second is two equations that you need to solve

- xapproachesinfinity

well seems onece again i'm wrong
proportions works with the second
22 out of 50 are females
out of 800
x=800 times 22 all divided by 50

- xapproachesinfinity

see how much is that

- anonymous

22 divided by 50?

- xapproachesinfinity

noo 800 times 22 all divided by 50

- xapproachesinfinity

let's the first...

- anonymous

352

- math&ing001

First one, you have 30 fish among 84, that's \(\frac{ 30*100 }{ 84 } = 35.7\)% of total fish taged, and you need to find what's the number at 100%.
Second, same thing 22 females out of 50, that's 44%. Find 44% of 800.
Last 4 wires are defective out of 100, that's 4% defective wires, find 4% of 750.

- xapproachesinfinity

in case you got confused my way and his are the same alright
proportions are tied to percentages :)

- xapproachesinfinity

you still get the same answers

- xapproachesinfinity

woow the guy is gone i'm speaking to my self lol

- anonymous

so question 5 is 352

- xapproachesinfinity

yes

- anonymous

what about questions 6 and 4?

- xapproachesinfinity

6 i answer see above
4 the @math&ing001 answered you

- xapproachesinfinity

6 same way you get 30

- anonymous

ok thanks

- xapproachesinfinity

no problem

- anonymous

for #4 i got A?

- xapproachesinfinity

seems good to me

- math&ing001

Not quite... if the fish he tagged (180) represents 35.7% of the total, don't you think the number of total fish would actually be bigger ?

- math&ing001

120*

- anonymous

ya it should

- anonymous

i think its B or C cause D is to big right?

- xapproachesinfinity

i must say the language used in the first throws a bit off
and that was the reason i skipped it in the first place

- xapproachesinfinity

me*

- xapproachesinfinity

in other words i didn't quite understand the problem

- math&ing001

Well we shouldn't be guessing if we can calculate:
120 is 35.7% of the total, so the total would be 120*100/35.7

- anonymous

i got C

- anonymous

@xapproachesinfinity could you give @math&ing001 a medal so that i could give you a medal, since you both were really a big help?

- xapproachesinfinity

i did give him a medal

- anonymous

Thanks

- xapproachesinfinity

no problem
