during one year, seven coyotes in a population die. eight immigrate into the population, but none emigrate. if the overall population growth is 13 coyotes, what was the birth rate of coyotes during the year? use this formula: population growth = (birth rate + immigration) - (death rate + emigration) 7 11 12 15

Answer

Explanation:

Step1: Identify given values

Let birth rate be $b$. Death rate $d = 7$, immigration $i=8$, emigration $e = 0$, population growth $g=13$.

Step2: Substitute into formula

$g=(b + i)-(d + e)$ becomes $13=(b + 8)-(7+0)$.

Step3: Simplify the right - hand side

$(b + 8)-(7+0)=b + 8 - 7=b + 1$. So, $13=b + 1$.

Step4: Solve for $b$

Subtract 1 from both sides: $b=13 - 1$.

Answer:

12
