Answer:
A. A dependency relationship related to a hobby or sport could be the relationship between the amount of time spent practicing a particular sport and the level of skill achieved in that sport. This relationship suggests that the more time an individual dedicates to practicing a specific sport, the higher their skill level will become.
B. In this relationship, the independent variable is the amount of time spent practicing the sport. This variable can be controlled and manipulated by the individual engaging in the hobby or sport. The dependent variable is the level of skill achieved in that particular sport. This variable is influenced by the independent variable and changes as a result of variations in practice time.
C. The dependency relationship between practice time and skill level in a hobby or sport can be expressed using words as follows: "The level of skill achieved in a particular sport depends on the amount of time dedicated to practicing that sport."
D. The dependency relationship using function notation can be written as follows: Let S(t) represent the skill level achieved in a particular sport as a function of time, where t represents the amount of time spent practicing. Therefore, S(t) = f(t), where f is the function that relates practice time to skill level.
