Question

There is a large jar filled with jellybeans as the prize for guessing the closest to the number of jellybeans in the jar. What would be a good way to estimate the number of jellybeans?Count as many jellybeans as possible, then multiply the number by [Math Processing Error).Count the number in the top row, then multiply by the number of rows present.Randomly select a number between [Math Processing Error) and [Math Processing Error) using a random number generator.Weigh the jar, and divide by the weight of a single jellybean.

Answer 1

To estimate the number of jellybeans in the jar, there are two good methods: weighing the jar and dividing the weight by the weight of a single jellybean, or counting the number of jellybeans in a small sample and using that as a representative sample.

Step-by-step explanation:

To estimate the number of jellybeans in the jar, one way is to weigh the jar and divide the weight by the weight of a single jellybean. This method assumes that all jellybeans weigh the same. Another way is to count the number of jellybeans in a small sample and use that as a representative sample of the entire jar. For example, if you count 10 jellybeans and 2 of them are red, you can estimate that 20% of the jellybeans in the jar are red.

Therefore, to estimate the number of jellybeans in the jar, I would suggest either weighing the jar and dividing the weight by the weight of a single jellybean, or counting the number of jellybeans in a small sample and using that as a representative sample.

Answer 2

Weigh the jar, and divide by the weight of a single jellybean.

Here, we want to find a good way of estimating the number of jellybeans in the jar.

The best answer here is to weigh the jar and divide by the weight of a single jellybean.

This is because each of the jellybean contributes to the weight of the jar. And since the weight of one of the jellybeans almost roughly equal that of the rest, then the addition of all these weights give the total weight of the jar

So by dividing the weight of the jar by the weight of a sinkgle jellybean, we get the number of jellybeans present in the jar.
