The students measured length during a science experiment, they got 12 cm. But the actual measurement was 14.25cm. what was the percent error?

Percent error = 15.79%

Step-by-step explanation:

Given the following data;

Experimental value = 12cm

Actual value = 14.25cm

To find the percentage error;

Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.

Mathematically, it is given by this expression;

Substituting into the equation, we have;

Percent error = 15.79%

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.
