Question

Sam counts how many people came to the local political meeting. He counts 72 people, but forgot about the 4 people sitting behind him.
The percent error in his calculation is __________.

Answer 1

Answer:

The percent error in his calculation is 5.26%.

Step-by-step explanation:

Percent error:

Number of misses multiplied by 100 and divided by the correct value.

In this question:

Total of 72 + 4 = 76 people. 4 were missed, so:

$E = \frac{4(100)}{76} = \frac{400}{76} = 5.26$

The percent error in his calculation is 5.26%.
