Question

by tracking births, deaths, immigrants, and emigrants, scientists can measure population growth. population growth = (births + immigrants) - (deaths + emigrants) imagine a population of 11 chickens (1 rooster and 10 hens) living on a farm. over the course of one month, 20 new chicks were born into the flock, 3 of which died. the farmer added 1 new hen to the flock. what was the population growth over this month - long period? chickens

Explanation:

Step1: Identificar valores

Nacimientos = 20, Muertes = 3, Inmigrantes = 1, Emigrantes = 0

Step2: Aplicar fórmula

Usamos la fórmula: población crecimiento=(nacimientos + inmigrantes)-(muertes + emigrantes)
Sustituimos valores: $(20 + 1)-(3+0)$

Step3: Realizar cálculos

$21 - 3=18$

Answer:

18
