Question

On a 92 point test, a student scored 87 points. What is the percent error

Answer 1

Percent error = 5.44%

Step-by-step explanation:

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;

`Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100`

Given the following data;

Experimental value = 87

Theoretical value = 92

Substituting into the equation, we have;

`Percent \; error = \frac {87 - 92 }{ 92} *100`

The negative value is ignored because we're trying to get the error.

`Percent \; error = \frac {5 }{ 92} *100`

`Percent \; error = 0.0544 *100`

Percent error = 5.44%
