A. A class rolls a number cube 100 times and records the results. use these to predict how many times the class will roll the number 4 in 1,000 trials. Show your work.

B. Use these results to predict how many times an odd number will be rolled in 10,000 trials

Answer:

A. In 1000 trials the number 4 could be rolled about 200 times.

B. In 10,000 trials an odd number will be rolled about 4700 times.

Explanation:

A. To get to 1000 from 100 you multiply it by 10.

So I just multiplied all the numbers by 10.

To prove I'm right, I multipled each number by 10 and added them together, that got me 1000.

So 4 will be rolled about 200 times in 1000 trials.

B. To get 10000 from 1000 you mulitply 1000 by 10 to get 10000.

So I took each number from the previous experiment and multiplied it by 10 again. Or you could multiply the numbers from the basic chart and multiply it by 100 instead.

This question wants all the odd numbers.

Multiply 15 by 100 = 1500

Multiply 17 by 100 = 1700

Multiply 15 by 100 = 1500

Add those all together and you get 4700.

So in 10,000 trials an odd number will probably be rolled 4700 times.
