Question

A zookeeper predicted that the weight of a newborn lion would be 2.8 pounds.

Answer 1

There is 20% error in zookeeper's calculations.

Step-by-step explanation:

Given,

Approx weight of newborn lion = Approx value =2.8 pounds

Exact weight of newborn lion = Exact value = 3.5 pounds

Percent error = $\frac{|approx-exact|}{exact}*100$

Percent error = $\frac{|2.8-3.5|}{3.5}*100$

Percent error = $\frac{|-0.7|}{3.5}*100$

Percent error = $\frac{70}{3.5}$

Percent error = 20%

There is 20% error in zookeeper's calculations.
