Question Analysis:
We are given the previous year plant population of Salvinia plants, which is 23. We are also given that 7 new plants are added to the previous year's population. We need to calculate the birth rate based on this information.
Calculation:
To calculate the birth rate, we need to find the percentage increase in the population from the previous year to the current year.
Step 1: Calculate the total population in the current year.
Total population = Previous year population + New plants added
Total population = 23 + 7
Total population = 30
Step 2: Calculate the increase in population.
Increase in population = Total population - Previous year population
Increase in population = 30 - 23
Increase in population = 7
Step 3: Calculate the birth rate.
Birth rate = (Increase in population / Previous year population) x 100
Birth rate = (7 / 23) x 100
Birth rate ≈ 0.3043 x 100
Birth rate ≈ 30.43%
Answer:
The birth rate, rounded to one decimal place, is approximately 0.3 or 30.4%. Therefore, the correct answer is option A.
We are given the previous year plant population of Salvinia plants, which is 23. We are also given that 7 new plants are added to the previous year's population. We need to calculate the birth rate based on this information.
Calculation:
To calculate the birth rate, we need to find the percentage increase in the population from the previous year to the current year.
Step 1: Calculate the total population in the current year.
Total population = Previous year population + New plants added
Total population = 23 + 7
Total population = 30
Step 2: Calculate the increase in population.
Increase in population = Total population - Previous year population
Increase in population = 30 - 23
Increase in population = 7
Step 3: Calculate the birth rate.
Birth rate = (Increase in population / Previous year population) x 100
Birth rate = (7 / 23) x 100
Birth rate ≈ 0.3043 x 100
Birth rate ≈ 30.43%
Answer:
The birth rate, rounded to one decimal place, is approximately 0.3 or 30.4%. Therefore, the correct answer is option A.
