wombats are animals that are native to australia and are related to kangaroos. to estimate the wombat population, professor beasleys research group trapped 28 wombats and tagged them. they returned the tagged wombats to the wild, and a week later, trapped 300 wombats. of those wombats, 21 were marked. to the nearest whole number, what is the best estimate for the wombat population?
Answer
Answer:
400
Explanation:
Step1: Set up proportion
Let $x$ be the total wombat population. The proportion is $\frac{28}{x}=\frac{21}{300}$.
Step2: Cross - multiply
$21x = 28\times300$.
Step3: Solve for $x$
$x=\frac{28\times300}{21}=\frac{8400}{21}=400$.
