(round answers for total interest to 0 decimal places, e. g. 825. round annual interest rate to 0 decimal places, e. g. 15%. use 360 days for calculation.) date of note terms maturity date principal annual interest rate total interest (a) april 1 60 days select a maturity date $660,000 14 % $enter total interest in dollars rounded to 0 decimal places (b) july 2 30 days select a maturity date 84,000 enter an annual interest rate in percentages rounded to 0 decimal places % $910 (c) march 7 6 months select a maturity date 196,000 15 % $enter total interest in dollars rounded to 0 decimal places

An important application of regression analysis in accounting is in the estimation of cost. by collecting data on volume and cost and using the least squares method to develop an estimated regression equation relating volume and cost, an accountant can estimate the cost associated with a particular manufacturing volume. consider the following sample of production volumes and total cost data for a manufacturing operation. production volume (units) total cost ($) 400 4000 450 5000 550 5400 600 5900 700 6400 750 7000 compute b 1 and b 0 (to 2 decimals if necessary). b 1 b 0 complete the estimated regression equation (to 2 decimals if necessary). = + x what is the variable cost per unit produced (to 1 decimal)? $ compute the coefficient of determination (to 4 decimals). note: report r 2 between 0 and 1. r 2 = what percentage of the variation in total cost can be explained by the production volume (to 2 decimals)? % the company's production schedule shows 500 units must be produced next month. what is the estimated total cost for this operation (to 2 decimals)? $
