Question

The black‐footed ferret was declared extinct in 1979, but a small population of the animals was found in Wyoming in 1981. Some of the wild ferrets were captured and bred in captivity. The animals bred in captivity were then reintroduced into the wild. Since their reintroduction, the total number of black-footed ferrets in the wild has increased to at least 1000 individuals. Suppose 146 ferrets are found in a population in the first year. In the next year, there are 183 ferrets in the same population. Calculate the growth rate from the first year to the second year. Express the growth rate as a percentage with at least two significant figures.

Answer 1

Answer:

The value is  $g = 25.3 \%$

Step-by-step explanation:

From question we are told that

   The  population in the first year is  $y_1 = 146$

     The  population in the next year is  $y_2 = 183$

Generally the growth rate is mathematically represented as

    $g = \frac{y_2 - y_1 }{y_1} * 100$

    $g = \frac{183 - 146}{146} *100$

    $g = 25.3 \%$
