To find Richard's shooting percentage for free throws, you can use the formula:
\[ \text{Shooting Percentage} = \left(\frac{\text{Number of Successful Free Throws}}{\text{Total Free Throws Attempted}}\right) \times 100 \]
In this case, Richard made 5 successful free throws out of 7 attempts:
\[ \text{Shooting Percentage} = \left(\frac{5}{7}\right) \times 100 \]
Calculating this gives:
\[ \text{Shooting Percentage} \approx 0.7143 \times 100 = 71.43% \]
Rounding it to one decimal place, Richard's shooting percentage for free throws is approximately 71.4%.
Thus, the correct answer is 71.4%.
