Question

during one year, eight turtles are born into a population. ten turtles immigrate into the population, but two emigrate to find mates. if the overall population growth is nine turtles, what was the death rate of turtles during the year? use this formula: population growth = (birth rate + immigration) − (death rate + emigration) ○ 7 ○ 9 ○ 11 ○ 29

Explanation:

Step1: Assign given values to variables

Let population growth = $9$, birth rate = $8$, immigration = $10$, emigration = $2$, death rate = $x$.

Step2: Substitute into the formula

$9 = (8 + 10) - (x + 2)$

Step3: Simplify the sum in parentheses

$9 = 18 - (x + 2)$

Step4: Rearrange to solve for $x$

$x + 2 = 18 - 9$
$x + 2 = 9$
$x = 9 - 2$
$x = 7$

Answer:

7
