Question

guided practice
water pressure increases 0.44 pounds per square inch (0.44 psi) with each increase of one foot in depth below sea level identify the independent and dependent
quantity in the situation.
a. depth; water pressure
b. water pressure; depth
c. number of fish; depth
d. amount of air in oxygen tank; water pressure
check answer
patterns and functions

Explanation:

The independent variable is the one that is changed or controlled in a scientific experiment to test the effects on the dependent variable. Here, the depth is being changed (each increase of one - foot in depth), and the water pressure is the variable that is affected by the change in depth. So, depth is the independent variable and water pressure is the dependent variable.

Answer:

B. water pressure; depth
