Your not the only with this question. Many kids have the same question.
Well, it is not difficult actually, all you have to do is think gets your books and ask the teacher.

You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.
I estimate the size of 125 to be very close to 125.It only takes a glance.
The advantage of the modified method is the improved accuracy - the error is of order h3 as opposed to h2, where h is the step size. Since the step size is required to be small for the methods to give fair approximations (h
by using the capture-recapture method which gives you the total size of organisms in a population.

Mark and recapture is a method commonly used in ecology to estimate an animal population's size where it is impractical to count every individual. A portion of the population is captured, marked, and released.
For extremely large populations, the best method to determine size is often statistical sampling. This involves taking a representative sample of the population and using statistical techniques to estimate the full population size. This method is efficient and cost-effective for large populations.
What reasonable estimate for the size of a cell's nucleus?
it is the same size of the thing in your pants.
The recommended method for determining the appropriate bike sizing in centimeters is to measure your inseam length and multiply it by 0.65. This will give you a rough estimate of the frame size that would be suitable for you. It is important to also consider other factors such as your height, riding style, and personal preference when choosing a bike size.
To estimate the population of turtles in a small pond using the mark and recapture method, first capture a sample of turtles, mark them in a non-invasive way, and release them back into the pond. Later, recapture another sample of turtles and note how many of them are marked. Based on the proportions of marked turtles in the recaptured sample, you can calculate an estimate of the total population size using mathematical formulas.
They used a method called "representative sampling" to obtain their estimate. The sky is divided into sections of equal size and the number of galaxies in one section are counted. The count from that one section is then multiplied by the total number of sections in the sky
The ecologist is using the mark and recapture method to estimate the population number of a certain species. This involves capturing, marking, and releasing a sample of individuals, then recapturing a new sample later to estimate the total population size based on the proportion of marked individuals in the second sample.
This answer depends on several factors: the size and shape of the envelope, the weight of your letter, and how quickly you need the letter to arrive. It is a safe to estimate a little over $1.00 USD to mail a letter from somewhere in the US to London, but the exact cost will vary slightly.
The mark-and-recapture method is useful for ecologists when estimating population size of mobile animals. By capturing, marking, and releasing a sample of individuals, then recapturing and noting how many marked individuals are within the sample, researchers can use this data to statistically estimate the total population size.
