Question

Trevor thought there would only be 8 teams in the soccer tournament, but there were 17. What was his percent error?

Answer 1

Answer:

Around 52.94%

Step-by-step explanation:

We can use the percentage error formula, which is

$\frac{|approx-exact|}{exact}\cdot100$.

The approximated value was 8, however the exact value was 17, so we can substitute inside the equation.

$\frac{|8-17|}{17}\cdot100 \\\\\frac{|-9|}{17}\cdot100 \\\\\frac{9}{17}\cdot100 \\\\0.5294...\cdot100 \\\\52.94$

Hope this helped!
