Problem Explanation:
The task involves identifying
independent variables and
dependent variables in given scenarios. Here's a brief overview of the terms:
-
Independent Variable: This is the variable that is manipulated or changed by the experimenter or observer. It is the cause.
-
Dependent Variable: This is the variable that changes in response to the independent variable. It is the effect.
Scenario 1:
Keira earns $11.50 for each hour she babysits.
#### Step-by-Step Solution:
1.
Identify the relationship: Keira earns money based on the number of hours she works. The amount of money earned depends on the number of hours worked.
2.
Determine the dependent variable: The amount of money earned is the outcome that changes based on how many hours she works. Therefore, the
dependent variable is:
-
Dependent Variable: Amount of money earned.
3.
Determine the independent variable: The number of hours she works is the factor that determines how much money she earns. Therefore, the
independent variable is:
-
Independent Variable: Number of hours worked.
#### Final Answer for Scenario 1:
-
Dependent Variable: Amount of money earned
-
Independent Variable: Number of hours worked

Scenario 2:
Omar earns 2 points for each basket he makes during his basketball game.
#### Step-by-Step Solution:
1.
Identify the relationship: Omar earns points based on the number of baskets he makes. The total points scored depend on the number of baskets made.
2.
Determine the dependent variable: The total points scored is the outcome that changes based on how many baskets Omar makes. Therefore, the
dependent variable is:
-
Dependent Variable: Total points scored.
3.
Determine the independent variable: The number of baskets made is the factor that determines how many points Omar scores. Therefore, the
independent variable is:
-
Independent Variable: Number of baskets made.
#### Final Answer for Scenario 2:
-
Dependent Variable: Total points scored
-
Independent Variable: Number of baskets made
---
Final Answers:
1.
Scenario 1:
- Dependent Variable:
Amount of money earned
- Independent Variable:
Number of hours worked
2.
Scenario 2:
- Dependent Variable:
Total points scored
- Independent Variable:
Number of baskets made
Boxed Final Answer:
\[
\boxed{
\begin{array}{ll}
\text{Scenario 1:} & \text{Dependent Variable: Amount of money earned} \\
& \text{Independent Variable: Number of hours worked} \\
\text{Scenario 2:} & \text{Dependent Variable: Total points scored} \\
& \text{Independent Variable: Number of baskets made}
\end{array}
}
\]
