3 9) Lea collects coins. Over a three-year period she collected 1,000 nickels. After organizing them by year, she found that the number of nickels from a given year was related to the number minted that year: Minted (100 mill.) In Sample Lea discovered that this can be modeled by the equation y = 2.72x 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 her sample. # In Sample # Minted (100 million) a) What does the slope of the line represent? b) What does the y-intercept of this function represent? c) Using this model, in a sample of 1,000 nickels how many would you expect to be from a year in which 8 hundred million were minted? Round your answer to the nearest whole number. d) According to the model, how many nickels from a year in which 23 hundred million were minted would you expect to find in a sample of 1,000? Round your answer to the nearest whole number. e) A sample of 1,000 nickels contains 20 from a particular year. According to the model, how many would you expect to have been minted that year? Round your answer to the nearest tenth of a hundred million.
