I need help matching these up.

Relevant Range Match the definitions to the answers on the left Fixed Cost Use the drop down in each box and select the matching number Variable Cost Regression Analysis Discretionary Fixed Cost Mixed Cost High-Low Method Scattergraph Method Committed Fixed Cost Account Analysis Method 1 A cost that changes in total with changes in volume of activity. 2 Uses historical information from several reporting periods to estimate costs. 3 A visual representation of the cost and activity data over a time period. The resulting chart is used to identify and separate the fixed and variable components of a cost. 4 Activity for which cost behavior patterns are likely to be accurate 5 A fixed cost that cannot easily be changed in the short run. 6 A cost that is a combination of fixed and variable costs. 7 A cost that does not change in total with changes in volume of activity. 8 A fixed cost that can be changed in the short run without having a significant impact on the organization. 9 Yields the most accurage estimate of fixed and variable costs assuming there are no unusual data points. 10 This approach requires an experienced employee review the appropriate accounts and determine whether the costs in each account are fixed or variable
