Suppose the population of a country in 1985 was 145 million. In 1995 it was 190 million. Use the formula P = Ae kt to setup an expression to estimate the population of the country in 2005.
Given two data points (1985, 145 million) and (1995, 190 million), you can solve for A and k in the general exponential growth formula. Once you have A and k, you can use these values to estimate the population in 2005 by substituting t = 20 (2005 - 1985) into the formula. Round your estimate to the nearest whole number.
The primacy index of a country's population can be calculated by dividing the population of the largest city by the total population of the country and multiplying by 100. This index is used to measure the level of urban concentration within a country. A high primacy index indicates that the largest city has a significantly larger population compared to other cities in the country, while a low primacy index suggests a more dispersed population distribution.
To calculate the natural increase in a country, subtract the number of deaths from the number of live births within a specific period, usually a year. The formula for natural increase is: Natural Increase = Births - Deaths. This provides the net growth rate of the population due to natural factors.
Four ways to determine population size include conducting a census, using statistical sampling methods, employing satellite imagery and remote sensing, and analyzing demographic data. Each method has its own advantages and limitations depending on the population size and distribution.
The percent error is calculated as (|estimated population - actual population| / actual population) x 100. Substituting in the given values, we get (|77500 - 75000| / 75000) x 100 = (2500 / 75000) x 100 = 0.0333 x 100 = 3.33%.
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.
average income of a country = total income of the country÷ population of the country

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.
This formula may be I7Cl but I suppose that this compound doesn't exist.
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.
GP2 and GP3 and i suppose A1GP when it existed
I suppose that the chemical formula P2O doesn't exist.
I suppose that you think to a chemical formula. Example: table salt (sodium chloride) has the chemical formula NaCl.
I suppose that the chemical formula P2O doesn't exist.
I suppose an error. Is Cl2 ?
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.
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).
