Will records the wins and losses for his high school basketball team each year. He notices that the ratio of wins to losses has been consistent each year.

Using the information in the table, how many losses should he predict for next year if the number of games won is 27?

A. 1
B. 3
C. 6
D. 9


Sagot :

To predict the number of losses for next year based on the provided historical data, we will follow these steps:

1. Identify and List the Wins and Losses:
- Year 1: 18 wins and 2 losses
- Year 2: 45 wins and 5 losses
- Year 3: 36 wins and 4 losses
- Next year (Predicted): 27 wins and \( x \) losses

2. Calculate the Win-to-Loss Ratio for Each Year:
- Year 1: \( \frac{18}{2} = 9 \)
- Year 2: \( \frac{45}{5} = 9 \)
- Year 3: \( \frac{36}{4} = 9 \)

3. Determine the Average Win-to-Loss Ratio:
- Each year has a win-to-loss ratio of \( 9 \)
- The average ratio is thus \( 9 \)

4. Use the Average Ratio for Prediction:
- Given that the team's performance is consistent, we assume the same ratio for the upcoming year.
- Therefore, with 27 wins predicted next year, the ratio \( 9 \) should be used to find the expected number of losses.

5. Set Up the Proportion and Solve for \( x \):
- Ratio: \( \frac{\text{wins}}{\text{losses}} = 9 \)
- For 27 wins: \( \frac{27}{x} = 9 \)

6. Solve the Equation for \( x \):
[tex]\[ \frac{27}{x} = 9 \][/tex]
Multiply both sides by \( x \) to isolate \( 27 \) on the left side:
[tex]\[ 27 = 9x \][/tex]
Divide both sides by \( 9 \) to solve for \( x \):
[tex]\[ x = \frac{27}{9} = 3 \][/tex]

Therefore, Will should predict 3 losses for the next year if the number of games won is 27. Thus, the correct answer is:

[tex]\[ \boxed{3} \][/tex]
