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 zookeepers's percent error?

Answer 1

Answer:

20%

Step-by-step explanation:2.8-3.5 then divide that by 3.5 and multiple the answer by 100 to get the percent

Answer 2

Answer: 20%

Step-by-step explanation:

According to the  zookeeper ,

The predicted weight of the newborn lion = 2.8 pounds

The actual weight of the newborn lion = 3.5 pounds

Now , the zookeepers's percent error = $\dfrac{|Predicted-actual|}{actual}\times100$

$=\dfrac{|2.8-3.5|}{3.5}\times100\%\\\\=\dfrac{|-0.7|}{3.5}\times100\%\\\\=\dfrac{0.7}{3.5}\times100\%\\\\=\dfrac{100}{5}\%=20\%$

Hence, the zookeepers's percent error = 20%.
