1. Let's clarify the problem: You are asking if option d is correct because a Pareto chart is a combination of a line graph and a bar chart. 2. A Pareto chart is indeed a type of chart that combines two types of graphs: bars and a line. 3. The bars represent the frequency or count of categories in descending order. 4. The line graph represents the cumulative percentage of the total. 5. This combination helps to identify the most significant factors in a dataset by showing both individual and cumulative impacts. 6. Therefore, option d is correct because a Pareto chart is a combination of a bar chart and a line graph. Final answer: Yes, d is correct because a Pareto chart combines a bar chart and a line graph.
