Chapter 6.4, Problem 17IP

To determine

To find: Percent error.

Answer to Problem 17IP

Percent error is $11.11\%$

Explanation of Solution

Given information:

Estimated height $=200$ meters

Actual height $=180$ meters.

Percent error $=\frac{A}{O}\times 100$

Where

  $A=$ Absolute value.

  $O=$ Actual value.

From given information

Estimated height $=200$ meters

Actual height $=180$ meters.

Absolute value = Estimated value $-$ Actual value.

  $\begin{array}{l}\Rightarrow A=200-180\\ \Rightarrow A=20\end{array}$

Therefore,

Percent error $=\frac{20}{180}\times 100$

  $\Rightarrow$ Percent error $=\frac{2000}{180}$

  $\Rightarrow$ Percent error $=11.11$

So, Percent error is $11.11\%$ .
