Question

To bill customers for water usage, one city converts the number of gallons used into units. This relationship is represented by the equation g = 748u, where g is the total number of gallons of water used and u is the number of units. Determine which statements about the relationship are true. Check all that apply. g is the dependent variable. u is the dependent variable. g is the independent variable. u is the independent variable. The two variables cannot be labeled as independent or dependent without a table of values. The two variables cannot be labeled as independent or dependent since any value can be selected for either.

Answer 1

For this we will analyze each statement:

A.) g is the dependent variable - This one is correct because it will depend on the value of u.

B.) u is the dependent variable. - This one is wrong because u is the independent variable.

C) u is the independent variable. - This one is correct because you can give the value to u and in return you can get value of g.

D.) the variables cannot be labeled without a table of values. - This statement is wrong   you can look for for the answer in the above statements.

E.) the variables cannot be labeled since any value can be selected for either. - This statement is also wrong.
