What will be the population doubling time of place if the annual population growth rate is one precent
Answers
Answer:
70/ PGR= 70/1= 70 years
Answer:
We may use a straightforward calculation known as the Rule of 70 to calculate how long it would take for a population to double at a single rate of growth. Basically, multiplying 70 by the yearly growth rate yields the doubling time (in years).
Explanation:
Step : 1 The "rule of 70" states that there is a significant link between a quantity's percent growth rate and its time to double, which may be used to calculate the doubling time for a quantity that is gradually increasing.
Step : 2 To determine when a population will double:
1. Calculate the population growth rate. Be certain that it remains steady.
2. Calculate the logarithm of one multiplied by the growth rate.
3. Divide the outcome by the logarithm of two.
4. The doubling time is solely independent on this one factor.
Step : 3 A population's growth rate may be calculated by subtracting the prior population size from the present population size, just like with any other growth rate calculation. Subtract that sum from the preceding measurement. To calculate the percentage, multiply it by 100. read more, since (1 + r/n) er/n, the natural log of 2 is divided by the rate of annual return to determine the doubling time in years. The rule of 69, sometimes known as doubling time, may be further extended as Doubling time = 0.69 / r = 69 / r%.
