To calculate the average number of heartbeats per second, you need the total number of heartbeats over a certain period and then divide by the total time.
If the graph shows a resting heart rate that doesn't vary significantly, you may be able to assume a constant heart rate from the values indicated.
Let's follow this logic step-by-step, assuming an average heart rate observed from the graph appears to be around 12 beats throughout the given time (from 0 to 12 seconds):
1. Determine the total number of heartbeats over the period:
If the heart rate consistently averages around 12 beats (assuming this value based on the y-axis), and if this is sustained for 12 seconds, we can calculate the total heartbeats as follows:
Total heartbeats = Average Heartbeats per second × Total Time
Total heartbeats = 12 beats/second × 12 seconds = 144 beats
2. Now, to find the average number of heartbeats per second over the 12 seconds:
Average beats per second = Total heartbeats / Total time
Average beats per second = 144 beats / 12 seconds = 12 beats/second
However, based on the options provided, none fit this calculation. That said, if the heart rate is indeed close to 2 or 3 beats consistently observed from that graph might fit better when compared to common resting heart rates.
Based on the options you've given, it would be prudent to choose based on the overall context of average resting heart rate if the previous calculation doesn't align correctly based on your visual representation on the specified graph:
**Final answer:** Either 2 beats per second or 3 beats per second might be more aligned as a safer assumption based on typical resting heart rates and their representations within this context.
Please confirm the numbers you see on the graph to choose the appropriate option!
