To calculate the expected win percentage using the expanded win percentage formula, we will use the following formula:
\[ \text{Win Ratio} = \frac{(\text{Runs Scored})^2}{(\text{Runs Scored})^2 + (\text{Runs Allowed})^2} \]
1. Calculate for the Cincinnati Reds with 786 Runs Scored and 760 Runs Allowed.
First, plug in the values for the Reds:
\[ \text{Runs Scored} = 786 \] \[ \text{Runs Allowed} = 760 \]
Calculating the squared values:
\[ (\text{Runs Scored})^2 = 786^2 = 617796 \] \[ (\text{Runs Allowed})^2 = 760^2 = 577600 \]
Now, substitute these values into the win ratio formula:
\[ \text{Win Ratio} = \frac{617796}{617796 + 577600} = \frac{617796}{1197396} \]
Calculating this gives:
\[ \text{Win Ratio} \approx 0.5164 \]
Rounding this to the nearest thousandth yields:
\[ \text{Win Ratio} \approx 0.516 \]
Now calculate expected wins in a 162-game season:
To find the expected number of wins:
\[ \text{Expected Wins} = \text{Win Ratio} \times \text{Total Games} \] \[ \text{Expected Wins} = 0.516 \times 162 \approx 83.592 \]
Rounding to the nearest whole number gives us:
\[ \text{Expected Wins} \approx 84 \]
2. For a Team that Scored 774 Runs and Allowed 666 Runs:
Using the same win ratio formula:
\[ \text{Runs Scored} = 774 \] \[ \text{Runs Allowed} = 666 \]
Calculating the squared values:
\[ (\text{Runs Scored})^2 = 774^2 = 599076 \] \[ (\text{Runs Allowed})^2 = 666^2 = 443556 \]
Now, substitute into the win ratio formula:
\[ \text{Win Ratio} = \frac{599076}{599076 + 443556} = \frac{599076}{1045632} \]
Calculating this gives:
\[ \text{Win Ratio} \approx 0.5725 \]
Rounding to the nearest thousandth:
\[ \text{Win Ratio} \approx 0.573 \]
Expected Wins in a 162-game Season:
Calculating expected wins:
\[ \text{Expected Wins} = 0.573 \times 162 \approx 92.754 \]
Rounding to the nearest whole number gives us:
\[ \text{Expected Wins} \approx 93 \]
Summary:
- Expected Win Ratio for Reds: 0.516
- Expected Wins for Reds: 84
- Expected Win Ratio for a team with 774 runs scored and 666 runs allowed: 0.573
- Expected Wins for that team: 93
