Question
Sarah is bringing treats to her elementary school class on her birthday. The number of treats she brings in is based on the number of students in her class.
t = the number of treats
s = the number of students
Choose the variables that is INDEPENDENT.
- s
- t
- Sarah
- All of the above
Hint:
In a given equation, the 2 variables viz. x & y can be bifurcated into Independent variable and dependent variable.
The independent variable can be referred to as the cause i.e. Its value is independent (does not change as per the other variables) of other variables. The dependent variable can be referred to as the effect. Its value depends on changes in the independent variable.
Generally, Independent variables are represented on the x-axis i.e. horizontal axis and Dependent variables are represented on the y-axis i.e. vertical axis.
The correct answer is: s
GIVEN-
t = the number of treats
s = the number of students
TO FIND-
Independent variable in the given scenario.
SOLUTION-
In the given scenario, we observe that the number of treats Sarah brings on her birthday is based on the number of students in her class.
We know that the number of students in the class is a given criteria. i.e. it is constant.
However, the number of treats Sarah brings will depend on the number of students in the class.
Hence, "number of students in the class" is the Independent variable in this situation.
FINAL ANSWER-
Option 'a' i.e. 's' is the correct answer to the given question.
