Question

You estimate that there are 44 marbles in a jar. The actual amount is 73 marbles. Find the percent error.

Answer 1

Percentage Error in counting the marbles in the jar is 39.72%

Explanation:

Estimated marbles in the jar = 44

Actual marbles in the jar = 73

⇒Error in Marbles = Number of actual Marbles - Estimated marbles

= 73 - 44 = 29

So, the error in counting marbles in the jar is 29.

Now,
`\textrm{Percentage Error}  = \frac{\textrm{Error in the Data}}{\textrm{Actual Data}}  * 100`

=
`(29)/(73)  * 100  = 39.72`

or, Percentage Error = 39.72%

Hence, the Percentage Error in counting the marbles in the jar is 39.72%
