and make sure you read carefully for the answer i will not make it easy for ya
Explanation:
Based on the scatterplot, it appears that there is a negative linear relationship between the chlorine level of water in a swimming pool and the hours of direct sunlight. This means that as the number of hours of direct sunlight increases, the chlorine level in the pool decreases.
If we follow the trend line to the point where the chlorine level reaches zero, we can estimate the number of hours of direct sunlight needed to completely deplete the chlorine in the swimming pool water.
Given the options, the best prediction would be 8 hours. However, please note that this is an estimation based on the trend observed in the scatterplot, and actual results may vary depending on various factors such as the initial chlorine concentration, temperature, and other environmental conditions. It’s always best to regularly test and adjust the chlorine levels in your pool to ensure it’s safe for swimming.
