To calculate the yearly average death rate for the intersection, you need to find the average number of deaths per year over the ten-year period. You can do this by dividing the total number of deaths (B) by the total number of years (10).
The formula for the yearly average death rate is:
\[ \text{Yearly average death rate} = \frac{B}{10} \]
Where:
- \( B \) is the total number of deaths,
- \( 10 \) is the number of years.
After performing this calculation, you will have the average annual death rate at the intersection.
