Question

A zookeeper predicted that the weight of a newborn lion would be 2.8 pounds. When the zoo’s lion gave birth, the newborn weighed 3.5 pounds. What is the zookeeper’s percent error?

Answer 1

Answer: 20%

Step-by-step explanation:

Given : The expected weight of new born lion = 2.8 pounds

The actual weight of new born lion = 3.5 pounds

The formula to find the percent error is given by :-

$\text{Percent error}=\dfrac{|\text{Expected value-Actual value}|}{\text{Actual value}}\times100\\\\\Rightarrow\ \text{Percent error}=\dfrac{|2.8-3.5|}{3.5}\times100\\\\\Rightarrow\ \text{Percent error}=\dfrac{0.7}{3.5}\times100\\\\\Rightarrow\ \text{Percent error}=20\%$

Therefore, the zookeeper’s percent error = 20 %

Answer 2

3.5 - 2.8 is 0.7 so the zookeerper was 0.7 pounds off
