Ответ:
Lower limit for H is given as = 7/10*(220-a) where a is the age of the person
a. We have to calculate the lower limit for a person whose age is 47
We substitute the age "a" = 47 in the above equation to calculate the lower limit .
Lower limit = 7/10*(220-47)
Lower limit = 7/10*173
Lower Limit = 1211/10 = 121.10 = 121 beats/minute (since we cannot have fractional beats)
Lower limit of the heart range in beats per minute = 121 beats/minute
