to estimate the population of reindeer in an area, researchers put marks on 22 reindeer. later, on a flight over the area, the researchers noted 11 marked reindeer out of the 310 reindeer they counted. to the nearest whole number, what is the best estimate for the reindeer population?
Answer
Explanation:
Step1: Set up proportion
Let $x$ be the total reindeer population. The proportion is $\frac{22}{x}=\frac{11}{310}$.
Step2: Cross - multiply
We get $11x = 22\times310$.
Step3: Solve for $x$
First, calculate $22\times310 = 6820$. Then $x=\frac{6820}{11}=620$.
Answer:
620
