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
112 beats per second
Based on the data provided, which consists of points 6, 9, 15, and 18 (assuming these points are representative of average heartbeats at a given time or in sequence), we don't have a clear indication of the time intervals between those points. However, we can try to infer the average number of heartbeats per second.
If we consider those points representing heartbeats and the points (6, 9, 15, 18) to be sequential without a defined time frame, we can't accurately determine the beats per second without additional information regarding the time interval between each heartbeat.
However, if you intended to phrase your question differently, and these points are to represent the total number of heartbeats at specific seconds:
- Point 6 could mean 6 beats by the 6th second,
- Point 9 could mean 9 beats by the 9th second,
- Point 15 could mean 15 beats by the 15th second, and
- Point 18 could mean 18 beats by the 18th second,
Then the heartbeat rate per second would be calculated by dividing the total number of beats by the total number of seconds. If we take the highest point, which is 18 beats by the 18th second, we have an average of:
18 beats / 18 seconds = 1 beat per second.
But let's consider points 6 and 9 to analyze if the pattern holds:
- 6 beats / 6 seconds = 1 beat per second,
- 9 beats / 9 seconds = 1 beat per second.
This consistency (1 beat per second) suggests that indeed, across the points given, the average might be 1 beat per second. However, since this option is not presented in the multiple-choice answers you provided, we must deduce that there may be a misunderstanding or error in the presentation of the data or the question.
None of the provided options (2 beats per second, 3 beats per second, 2/3 beat per second, 112 beats per second) correspond to the example calculation of 1 beat per second derived from the points given. If additional context or specific time intervals are provided, a more accurate answer can be concluded. Otherwise, based on the values stated, none of the multiple-choice answers would be correct.
