If MHR is in beats per minute and a is age in years, the formulas used to estimate MHR are: For females: MHR=226 – a Recently it has been suggested that a more accurate predictor of MHR for both males and females is given by MHR= 208 – 0.7a. For males: MHR=220 – a - (a) At what age do the old and new formulas give the same MHR for females? For males? For females, the MHR is the same in the two formulas at 60 years of age. V For males, the MHR is the same in the two formulas at 40 years of age. (b) Which of the following is true? The new formula predicts a lower MHR for young people and a higher MHR for older people than the old formula. JAN 7 14 MacBook Pro esc -> Search or type URL 个 23 2$ 3. 4. 10 R.
