Math Issue

Sampling techniques can be used to estimate physical quantities. To estimate a large quantity, you might measure a representative small sample and find the total quantity by "scaling up." To estimate a small quantity, you might measure several of the small quantities together and "scale down." In the following problem, describe your estimation technique and answer the question.

How thick is a penny? a nickel? a dime? a quarter? Would you rather have your height stacked in pennies, nickels, dimes, or quarters?

What is a good method for estimating the thickness of each coin?

A penny is mm thick.

(Round to one decimal place as needed.)

How thick is a nickel?

A nickel is mm thick.

(Round to one decimal place as needed.)

How thick is a dime?

A dime is mm thick.

(Round to one decimal place as needed.)

How thick is a quarter?

A quarter is mm thick.

(Round to one decimal place as needed.)

Stack some coins to a measureable height such as 2 inches, and then multiply the height of the stack by the number of coins in the stack. Do this for each type of coin.

Stack some coins to a measureable height such as 2 inches, and then divide the height of the stack by the number of coins in the stack. Do this for each type of coin.

Stack some coins to a measureable height such as 2 inches, and then divide the height of the stack by the number of coins in the stack. The thickness of the rest of the coins is about half of this quotient.

Take one of each coin and make a stack. Measure the height, and then divide the height of the stack by the number of coins in the stack.
