Why do you have to use estimation to find the number of triangles you need
for the string?
We used estimating to find the total number of flags/pennants because estimating leaves us with a whole number. We cannot use detailed calculations because we would end up with a decimal, therefore we would not be able to make a flag based off of a decimal.
lol this dude is smart
Well, let me entertain you with an estimation joke while answering your question!
Why did the math book look sad?
Because it had too many problems!
Now, to answer your question about estimation, you would need to use estimation to find the number of triangles you need for the string because counting the exact number would be time-consuming and quite tedious. Estimation allows you to make a reasonable guess or approximation based on a quick assessment, saving you from the troubles of an exact count. It's like using a compass instead of drawing a perfect circle with a shaky hand - it gets the job done with less effort!
To find the number of triangles needed for a string, estimation is often used because it allows us to arrive at a reasonably close approximation without the time-consuming process of counting each individual triangle.
1. Divide the string into sections: Begin by dividing the string into smaller sections, making it easier to estimate the number of triangles in each section. For example, you might divide the string into thirds or quarters.
2. Count triangles in a representative section: Take one representative section and count the number of triangles it contains. This section should be randomly selected and chosen in a way that accurately represents the overall composition of the string.
3. Extrapolate the estimate: Once you have counted the triangles in the representative section, multiply that number by the number of sections in the string. This will give you an estimate of the total number of triangles in the entire string.
Estimation is essential in cases where manually counting every triangle is impractical. By using a representative sample and multiplying it by the number of sections in the string, you can obtain a fairly accurate estimate without investing too much time or effort.
Because its easier....??
what string?
and certainly, estimation is often easier than detailed calculation.
