At a resting pulse rate of 77 beats per minute, the human heart typically pumps about 71 mL of blood per beat. Blood has a density of 1060 kg/m3. Circulating all of the blood in the body through the heart takes about 1 min for a person at rest. Approximately how much blood is in the body? volume of blood in body On average, what mass of blood does the heart pump with each heart beat? kg mass per heart...

You want to measure your resting pulse rate. You might count the number of beats in five seconds and multiply by 12 to get beats per minute. Consider counting the number of beats in 15 seconds and multiplying by 4 to get beats per minute. In what way will this improve the reliability of your measurement? a. This measurement will likely have a smaller variance, since you're multiplying by 4 instead of 12. b. You are less likely to make...

A multiple regression model is to be constructed to predict the
heart rate in beats per minute (bpm) of a person based upon their
age, weight and height.

(a) A person's "resting" heart rate is his or her normal heart rate measured while sitting still (and long after doing anything physically exerting). A nurse on Earth measures the resting heart rate of a patient as 66.0 beats/min. Imagine the patient travels aboard a spaceship moving with a constant speed of 0.89c with respect to the Earth. What would be the patient's resting heart rate (in beats/min) as measured by someone else aboard the ship? beats/min (b) Imagine an...
