For cynthia's third lab report, she calculated the mass of an object as it slid down an inclined plane. she got the following three masses.
1.20 kg
0.91 kg
1.08 kg
the true mass of the object is 1 kg.
cynthia's percent error was [blank]%.
enter your answer as the number that correctly fills in the blank, rounded to two decimal places, like this: 42.53

Percent error: 6.00%

Step-by-step explanation:

We find the mean of the three masses

Mean = 1.20 + 0.91 + 1.08 / 3

Mean = 1.06 kg

The experimental value of mass is = 1.06 kg

The actual value of mass = 1 kg

The percent error is: (experimental value - actual value/actual value)*100

Percent error : (1.06 - 1 / 1)*100

Percent error: 6.00%

answer: 38.47 is your answer

step-by-step explanation: hope i you and who ever sees this answer have a great rest of your day : )
