Question

laws have been instituted in florida to help save the manatee. to establish the number in florida, a sample of 95 manatees were marked and let free. a new sample was taken and found that there were 5 marked manatees out of 36 captured. what is the approximate population of manatees in florida? there are approximately manatees in florida.

Explanation:

Step1: Set up proportion

Let $x$ be the total population of manatees. The proportion is $\frac{95}{x}=\frac{5}{36}$.

Step2: Cross - multiply

$5x = 95\times36$.

Step3: Solve for $x$

$x=\frac{95\times36}{5}=95\times7.2 = 684$.

Answer:

684
