kayla's class went on a field trip to an aquarium . one tank had 30 clown fish. She miscounted the total number of clown fish in the tank and recorded it as 24 fish . What is Kayla's percent error?
%error=(((theoretical value)-(experimental value))/(theoretical value))×100% theoretical value= The actual value (in this case 30) experimental value= value you found (in this case 24) when you plug everything in you get ((30-24)/30)×100% which equals 20%. Therefore her percent error was 20%. I hope this helps. Let me know in the comments if anything is unclear.
