which statement is an inference that can be made by using the graph?\no jims heart rate was 60 beats per minute at the start of the test.\no jims maximum heart rate during the test was 140 beats per minute.\no jims heart rate increased steadily as he continued exercising.\no jims heart rate decreased quickly after 30 minutes since he is in good shape.

which statement is an inference that can be made by using the graph?\no jims heart rate was 60 beats per minute at the start of the test.\no jims maximum heart rate during the test was 140 beats per minute.\no jims heart rate increased steadily as he continued exercising.\no jims heart rate decreased quickly after 30 minutes since he is in good shape.

Answer

Brief Explanations:

  1. The first two statements are direct observations from the graph, not inferences. The graph clearly shows the starting heart - rate as 60 beats per minute and the maximum as 140 beats per minute.
  2. The third statement is also an observation as the graph shows a linear increase in heart - rate during exercise.
  3. The fourth statement is an inference. While the graph shows a quick decrease in heart - rate after 30 minutes, the reason “he is in good shape” is not directly shown on the graph but is a reasonable assumption based on general knowledge about physical fitness and heart - rate recovery.

Answer:

Jim's heart rate decreased quickly after 30 minutes since he is in good shape.
