To evaluate the statements correctly, we can use a number line where:
- The water level is established as the reference point (0).
- The diving board is above the water level, so it will be represented as a positive value.
- The bottom of the pool is below the water level and will be represented as a negative value.
Given:
- The height of the diving board is +4 feet above the water.
- The depth of the pool is 8 feet, which means the bottom of the pool is 8 feet below the water level, or -8 feet.
Now let's analyze each statement:
A. If 0 represents the height of the diving board, then +4 represents the water level and –8 represents the bottom of the pool.
- Incorrect. This misrepresents the heights.
B. If +4 represents the height of the diving board, then 0 represents the water level and –8 represents the bottom of the pool.
- Correct. This accurately defines the diving board, water level, and bottom of the pool.
C. If 0 represents the height of the diving board, then 4 represents the water level and 8 represents the bottom of the pool.
- Incorrect. This misrepresents the heights again.
D. If +8 represents the height of the diving board, then 0 represents the water level and –4 represents the bottom of the pool.
- Incorrect. This incorrectly defines the positions relative to the water level.
The correct statement is **B**: If +4 represents the height of the diving board, then 0 represents the water level and –8 represents the bottom of the pool.
- The water level is established as the reference point (0).
- The diving board is above the water level, so it will be represented as a positive value.
- The bottom of the pool is below the water level and will be represented as a negative value.
Given:
- The height of the diving board is +4 feet above the water.
- The depth of the pool is 8 feet, which means the bottom of the pool is 8 feet below the water level, or -8 feet.
Now let's analyze each statement:
A. If 0 represents the height of the diving board, then +4 represents the water level and –8 represents the bottom of the pool.
- Incorrect. This misrepresents the heights.
B. If +4 represents the height of the diving board, then 0 represents the water level and –8 represents the bottom of the pool.
- Correct. This accurately defines the diving board, water level, and bottom of the pool.
C. If 0 represents the height of the diving board, then 4 represents the water level and 8 represents the bottom of the pool.
- Incorrect. This misrepresents the heights again.
D. If +8 represents the height of the diving board, then 0 represents the water level and –4 represents the bottom of the pool.
- Incorrect. This incorrectly defines the positions relative to the water level.
The correct statement is **B**: If +4 represents the height of the diving board, then 0 represents the water level and –8 represents the bottom of the pool.
