To determine the average number of heartbeats per second from the given data, we first need to find the total number of heartbeats and the total time.
The y-axis represents heartbeats from 0 to 18. As the y-values go from 0 to 18 in increments of 3, the possible heartbeats are 0, 3, 6, 9, 12, 15, and 18.
Assuming the heart rate stayed consistent over the entire time, we can use the maximum value (18 beats) at the maximum time value (12 seconds) to find the average.
If the maximum heart rate is 18 and was constant throughout the range of 0 to 12 seconds, the total number of heartbeats would be:
Total heartbeats = heart rate * time = 18 beats/minute * 12 seconds / 60 seconds/minute = 3.6 beats
So for the average heart rates calculated over the entire time:
Average number of beats per second = Total heartbeats / total time = (3.6 beats) / 12 seconds = 0.3 beats per second.
However, if the calculations are based on heartbeats per increments of 2 seconds where the ratio appears consistent, and assuming, as indicated, the presentation leads to constant heartbeats, we need to check given values.
If we analyze the options given based on average heartbeat counts related to smaller intervals, we could find that the average rate given would be:
For total heartbeats max being 18 at a stabilized rate, we could recheck on focused listed responses based on per second enclosing:
The average would fall more clearly under a consistent count of maximum 3 beats per second in balance of options.
The best and most accurate choice provided in your list appears to be:
**3 beats per second.**
