Answer:
graph d) is the most accurate representation of the relationship between Maximum Heart Rate (MHR) and Age according to the given formula.
Step-by-step explanation:
To determine which graph shows the relationship between Maximum Heart Rate (MHR) and Age based on the given formula, we need to understand how the two variables are related.
According to the formula MHR = 205.8 – (0.685 × Age), as the age increases, the MHR decreases. This means that there is a negative correlation between age and MHR.
To visualize this relationship, we can consider the following:
- Graph a) should show a decreasing line, with the MHR decreasing as the age increases.
- Graph b) should show a horizontal line, which does not represent the negative correlation described by the formula.
- Graph c) should show an increasing line, which contradicts the negative correlation described by the formula.
- Graph d) should show a decreasing line, with the MHR decreasing as the age increases.
Based on the explanation above, graph d) is the most accurate representation of the relationship between Maximum Heart Rate (MHR) and Age according to the given formula.
