MY NOTES ASK YOUR TEACHER The table below shows the number A, in thousands, of federal arrests for methamphetamine t years after 2006.t (Round regression line parameters to two decimal places.) t = years since 2006 A = thousands of arrests O 5.85 5.54 4.72 4.70 Find the equation of the regression line for A as a function of t. A(t) = The following table shows the length, in meters, of the winning long jump in the Olympic Games for the indicated year. (One meter is 39.37 inches. ) Year 1900 1912 Length 7.19 7. 7.60 (a) Find the equation of the regression line that gives the length as a function of time. (Let t be the number of years since 1900 and L the length of the wining long jump, in meters. Round the regression line parameters to three decimal places.) L(t) = (b) Explain in practical terms the meaning of the slope of the regression line. In practical terms the meaning of the slope, meter per year, of the regression line is that each year the length of the winning long jump increased by an average of meter, or about inches. Find the equation of the regression line for the following data set. y = Find the equation of the regression line for the following data set. (Round the values to two decimal places.) y = The regression line for a living sales S, in dollars, t years after 2016 is S = 220t + 2300. (a) Explain in practical meaning of the slope O The slope of 2300 dollars per year means that sales for the pertinent period are decreasing by $2300 each year. O The slope of 220 dollar are decreasing by $220 each year. The slope of riod are increasing by $220 each year The slope of 2300 dollars per year mea sales for the pertinent period are increasing by $2300 each year. The slope of 2300 dollars means the initial sales are 2300 dollars in 2016 (b) What sales are indicated for 2018? ""The percentage of employees who cease their employment during a year is referred to as employee turnover, and it is a serious issue for" businesses. The following table shows the cost, in millions of dollars, to a certain company for a given employee turnover percentage in a year. E = employee turnover C = cost 10 20 (a) Show that the data can be modeled by a linear function. For each increase in employee turnover by ten percent the cost increases by million dollars. (b) Find the slope of the linear function million dollars per percentage point (c) Find a linear model for the data C(E) = (d) Use the result from part (c) to find the cost to the company if employee turnover is 25% in a year. million dollars Find the equation of the regression line for the following data set. (Round the values to two decimal places.) y = * 2 3 4
