Question

students notice that water use varies from year to year. they want to design a model to predict future water use.
what three pieces of data will be most helpful to make accurate predictions about total water use?
a. water temperature
b. number of dams in the area
c. current water use per person
d. population growth projections
e. water quality and contaminant levels
f. weather conditions like air temperature and precipitation

Explanation:

• Current per-person water use (C) is a baseline for total use calculations.
• Population growth projections (D) show how the number of water users will change, directly impacting total use.
• Weather conditions (F) affect outdoor water use (like irrigation) and water availability, which influences consumption patterns.

Other factors like water temperature, dam count, and water quality have less direct impact on predicting total annual water use.

Answer:

C. current water use per person
D. population growth projections
F. weather conditions like air temperature and precipitation
