Question

4: The number of nickels from a particular year found in a sample of 1,000 is related to the number of nickels that were minted that year. This can be expressed as y=2.04x+0.806 where x is the number of nickels minted in a particular year in hundreds of millions and y is the number of nickels from that year in a sample of 1,000.What does the slope of the line represent?

Answer 1

The answer is the D option.

The reason is that the slope shows the proportion of growth, in this case, is positive, which means that while x grows y will do it in the given proportion, and x is the value of nickels in a hundred million, therefore y will be the expected nickles from a particular year.
