Accepted Solution

A:
Answer:123.9 ≈ 124 beats per minuteStep-by-step explanation:Data and formula provided in the question:Age = 43 years oldThe Formula for lower limit of range is given as:lower limit of range = [tex]\frac{7}{10}(220-\textup{Age})[/tex]Thus, on substituting the respective values, we getlower limit of range = [tex]\frac{7}{10}(220-43)[/tex]orLower limit of range = 123.9 ≈ 124 beats per minute
