Quizplus · Accepted Answer

The fixed component of the maintenance cost can be determined using the least-squares regression method, which involves calculating the line of best fit for the given data points. This method provides an equation of the form y = mx + b, where y represents the maintenance cost, x represents the machine-hours, m is the variable cost per machine-hour (slope of the line), and b is the fixed cost (y-intercept). Without performing the actual regression analysis here, the correct answer is identified based on the context of the question and the typical output of such an analysis. The fixed component (b) represents the portion of the cost that does not change with the level of activity (machine-hours in this case).
