For the following exercises, consider this scenario: The profit of a company increased steadily over a ten-year span. Thefollowing ordered pairs show the number of units sold in hundreds and the profit in thousands of over the ten-yearspan, (number of units sold, profit) for specific recorded years:

- For the following exercises, consider this scenario: The profit of a company increased steadily over a ten-year span. Thefollowing ordered pairs show the number of units sold in hundreds and the profit in thousands of over the ten-yearspan, (number of units sold, profit) for specific recorded years: (46,250),(48,305),(50,350),(52,390),(54,410). Predict when the profit will exceed one milliondollars.arrow_forwardFor the following exercises, consider this scenario: The population of a city increased steadily over a ten-year span. Thefollowing ordered pairs shows the population (in hundreds) and the year over the ten-year span, (population, year) forspecific recorded years: (4,500,2000);(4,700,2001);(5,200,2003);(5,800,2006) Use linear regression to determine a function y, where the year depends on the population. Round to threedecimal places of accuracy.arrow_forwardFor the following exercises, consider this scenario: The population of a city increased steadily over a ten-year span. Thefollowing ordered pairs shows the population (in hundreds) and the year overthe ten-year span, (population, year) forspecific recorded years: (4,500,2000);(4,700,2001);(5,200,2003);(5,800,2006) What is the correlation coefficient for this model?arrow_forward

Predict when the profit will dip below the $25,000threshold.arrow_forwardFor the following exercises, consider this scenario: The profit of a company decreased steadily overa ten-year span.The following ordered pairs show dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span (number of units sold, profit) for specific recorded years: (46,250),(48,305),(50,350),(52,390),(54,410). Use linear regression to determine a function y,where the profit in thousands of dollars depends onthe number of units sold in hundreds.arrow_forward
- For the following exercises, refer to Table 9. Use a graphing calculator to create a scatter diagram of the data.arrow_forwardFor the following exercises, consider this scenario: The population of a city increased steadily overa ten-year span. The following ordered pairs show the population and the year over the ten-year span (population, year) for specific recorded years: (3,600,2000);(4,000,2001);(4,700,2003);(6,000,2006) 45.
