A student took her pulse three times while lying at rest and recorded the following values: 16 beats, 20 beats, and 18 beats in 20 seconds. the average resting heart rate for the student is 21 beats/minute
42 beats/minute
54 beats/minute
72 beats/minute
90 beats/minute

54 beats/minute

Explanation:

First find the average heart rate from the data given

16+20+18=54

54/3=18

So her average heart rate for 20 seconds is 18

To find her heart rate in beats per minute multiply 18 times 3 because 20 seconds is a third of a minute

18x3=54

So, her average resting heart rate in beats/minute is 54

explanation:

plz give me the characteristics.

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this
