b

anonymous · Answer

The percentage will be 
(15 - 10)/15 = 1/3 = 33%

anonymous · Answer

thank you!

anonymous · Answer

{[(experimental value)-(theoretical value)]/(theoretical value)}*100

[(15ft-10ft)/(10ft)]*100=50%

anonymous · Answer

which one would be the theoretical value and which the experimental?
i figure since the 15ft was a result of her action it is experimental, and since the required minimum space is 10ft that would be the theoretical value.

anonymous · Answer

nevermind lol

a_clan · Answer

15 should be theoretical. It is the allowable distance

anonymous · Answer

I don't think that's correct, jmw417.
|(estimate - actual)/actual|
is the percentage error. The error you make must be related to the actual value of the variable,

anonymous · Answer

yes i fell victim to speed reading on this one. i see that the 10 ft is her experimental value and the 15 ft is the theoretical allowable distance. My bad folks!

anonymous · Answer

That's ok. No harm done, I am sure :)

anonymous · Answer

what is the answer

anonymous · Answer

It isn't 33%. I tried that and it marked me wrong.

anonymous · Answer

the answer would be 50 %
