What is the average number of heartbeats per second? (1 point) Graph: Point 6,Point 9 point 15, point 18
2 beats per second
3 beats per second
2/3 beat per second
1 1/2 beats per second
To determine the average number of heartbeats per second, one would typically calculate the average beats over a minute and divide by 60 seconds to find the average beats per second. However, the information provided in your question is not sufficient to calculate this average because the points you've mentioned (Point 6, Point 9, Point 15, Point 18) don't provide any context or time frame.
Usually, a resting heart rate for adults ranges from 60 to 100 beats per minute (bpm). To find the average beats per second, you would take the number of beats per minute and divide it by 60 (since there are 60 seconds in a minute). For example, if the heart rate were 60 bpm, then:
60 beats / 60 seconds = 1 beat per second
Without additional information on what the points represent or how they relate to heartbeats or time, I'm unable to determine the correct answer from the choices provided. Please provide more detailed information or context for a more precise answer. If the points represent heartbeats at specific seconds, you would divide the total number of beats by the total number of seconds recorded to find the average number of beats per second.
