I'm worried too...
Add a 0 to the end
2,008,960 people.
52*sqrt(6) = 127.3734666247252611
It's not even remotely CLOSE to correct, as you can see.
Divide 14 by 70%
14/70% = 20
Subtract the amount of answers she got right from 20, since 20 is the total.
20-14=6
So, Lucy got 6 wrong.
See, if you were polite, people would not be rude. Please be a nicer person. Thank you! :)
n=(29.77-19.85)/6
n=(29.77-19.85)/6 = n=(124/75)
