Question

1. the chart above compares the daily water use per person to the price of water in selected countries. which conclusion can you correctly draw using only the data in the chart?

a. water use and water price are directly proportional.
b. increased water use causes water prices to decline.
c. increased water prices cause water use to decline.
d. high water use is generally correlated with lower water prices.
e. water resources are greater in the us than in other countries.

1. flushing the toilet and using the dishwater are examples of what?

a. a high - use water source
b. flowrate = gallons per minute
c. a low - use water source
d. gallons per use
e. gallons per event

1. taking a shower and washing dishes in the sink are examples of what?

Explanation:

For question 10:

• Analyze the relationship between water use and price from the chart.
• If water use and price are directly proportional, as price increases, water use should increase. But from the chart, higher - priced countries (like Germany) don't have the highest water use.
• If increased water use causes water prices to decline (negative causal relationship), there is no such indication from the chart.
• If increased water prices cause water use to decline (negative causal relationship), we can see that the US (lower - priced water) has relatively high water use compared to some higher - priced countries.
• High water use is generally correlated with lower water prices. We can observe from the chart that countries with relatively low water prices (e.g., the US) have relatively high water use.

For question 11:

• Flushing the toilet, using the dishwater, taking a shower, and washing dishes in the sink are all events (activities) that consume water.
• "Gallons per use" would be for something like a toilet flush (per flush), "flowrate = gallons per minute" is for a shower (water flow over time), "a low - use water source" is a more general water - saving device concept, and "a high - use water source" is the opposite. But flushing the toilet and using the dishwater etc. are about water - consuming events.

Answer:

1. D. High water use is generally correlated with lower water prices.
2. E. Gallons per event.
