Severity Rate given Injury Index Solution

Follow our step by step solution on how to calculate Severity Rate given Injury Index?

FIRST Step Consider the formula

R i = II \cdot \frac{1000}{I n \cdot I r}

Next Step Substitute values of Variables

∴

R i = 288 \cdot \frac{1000}{20 \cdot 800}

Next Step Prepare to Evaluate

∴

R i = 288 \cdot \frac{1000}{20 \cdot 800}

LAST Step Evaluate

∴

R i = 18
