How can the primacy index of a countrys population be calculated?
The primacy index can be calculated by the following formula: PI = C1/ (C1 + C2 + C3 + C4) * 100 PI = primacy index C1 = amount of people in the biggest city of the country C2 = amount of people in the second city of the country C3 = amount of people on the third city of the country C4 = amount of people in the fourth city of the country So you divide the population of the biggest city of the country by the sum of the four biggest cities in the country and multiply that by 100. If the PI is > or = to 50, then it is a primate city.
Calculate the natural increase in a country?
To calculate the natural increase of a population, you take the the countries' birth rate (number of live births per 1000 population per year) minus the countries' death rate (number of deaths per 1000 population per year) -- BR-DR
What are four ways to determining population size?
Sampling - counting the number of organisms in a small area and multiplying to estimate the number in a larger areaMark & Recapture - capture an organism & release it to remix with population. Then recapture some more in that area to determine population size. Formula is as follows: R (marked recaptures) / C (total in second sample) = M (marked initially) / N (total pop. size)Indirect Observation - estimating the population size by tracks, nest or other animal signs in an ecosystem.Direct Observation - count all members of a population in an ecosystem
Julie estimated her town's population at 77500 the actual population of her town is 75000 what is the percent error?
You take 75,000 minus the 77500 which is -2500 ( ignore the negartice) then divide that by the exact number 75000 which gives you .03 and move the decimal to the right two times. The answer is 30% have to follow a formula for percent error.
What is the formula would enable you to find out future population size as it's limited by population regulation?
The logistic growth equation is commonly used to model populations limited by regulation. It is given as: ( \frac{dN}{dt} = rN\left(1-\frac{N}{K}\right) ), where (N) is the population size, (r) is the growth rate, and (K) is the carrying capacity. This equation accounts for both exponential growth (when (N) is much smaller than (K)) and slower growth as the population approaches its limit.
What is the formula of average income?
average income of a country = total income of the country÷ population of the country
Below is the formula for calculating the number of years it takes for a population to double This formula uses the percent annual population growth rate or r If a country has an annual population g?
34 years 41 years
How do you calculate the effective population size?
The effective population size is calculated using a formula that takes into account factors such as the number of breeding individuals, genetic diversity, and population fluctuations over time. This formula helps estimate the genetic diversity and potential for evolution within a population.
Is the population of a country determined by births only?
No. Population is first determined from a census, then by using a formula that factors in such things as the birthrate, death rate, immigration and emigration.
How does the formula for the t test differ from the formula for the z test?
When we use a z-test, we know the population mean and standard deviation. When we use a t-test, we do not know the population standard deviation and thus must estimate this using the sample data that we have collected. If you look at your z-table and t-table, tcrit for df(infinity) = zcrit because at df(infinity) we would have an entire population and no longer need an estimate.
What is the name of P4O?
I suppose that the chemical formula P2O doesn't exist.
What is related to Formula one?
GP2 and GP3 and i suppose A1GP when it existed
What is the chemical formula for heptiodine monochloride?
This formula may be I7Cl but I suppose that this compound doesn't exist.
What poisonous gas is given the chemical formula C12?

What is the population of Bryan Texas?
The whole population of Bryan Texas is 885, 000 that was based from the Survey of the NSO of Republic of the BRYAN TEXAS. This was the result of the survey in the year 2011. To estimate its total population according to their given formula, last result Multiply by the letters that composing the name of the Country. It's 885, 000 X 10 and divide by 3.14 ( pie ). It's 2, 818 471. those are the people who are still living.
Formula for population growth without limits?
The formula for population growth is based on the formula for interest. The formula is Final Population is equal to Initial Population multiplied by e raised to the power of the product of the rate of growth multiplied by the time of growth, or P(f) = P(o) * e ^ (rt).
