1. **State the problem:** We have a scatter plot showing water temperature (°C) versus depth (meters) in Lake Turkana. We need to find: a. Temperature at 70 meters depth. b. Predicted temperature at the surface (0 meters). c. Depth where temperature is a little more than 27 °C. d. Describe the relationship between depth and temperature. 2. **Understanding the data:** The temperature decreases as depth increases, ranging from about 30 °C near the surface to about 25 °C at 100 meters. 3. **Answer a:** At 70 meters, the temperature is approximately 26 °C based on the scatter plot points. 4. **Answer b:** At the surface (0 meters), extrapolating from the trend, the temperature is about 30 °C. 5. **Answer c:** Temperature a little more than 27 °C occurs around 40 meters depth. 6. **Answer d:** The relationship is an inverse one: as depth increases, temperature decreases. This means temperature and depth are negatively correlated. Final answers: - Temperature at 70 meters: $26^\circ$C - Temperature at surface: $30^\circ$C - Depth for temperature a little more than 27 °C: approximately 40 meters - Relationship: Temperature decreases as depth increases, showing a negative correlation.
