Question

which of these is an example of an independent variable and its effect on a dependent variable? burgers and hotdogs water temperature and dissolving rate age and race cooking at home and ordering takeout

Explanation:

An independent variable is manipulated to see its effect on a dependent variable. In the case of water temperature and dissolving rate, water temperature can be changed (independent variable) and it affects the dissolving rate (dependent variable). Burgers and hot - dogs are just food items, age and race are characteristics not in a cause - effect relationship in this context, and cooking at home and ordering takeout are two different behaviors not in an independent - dependent variable relationship.

Answer:

water temperature and dissolving rate
