Mathematical Relationships

What is the difference between independent and dependent variables?

• Independent variables are manipulated or controlled by the researcher, while dependent variables are measured or observed and are affected by the independent variables.

• Independent variables are not affected by the dependent variables.

• Dependent variables are manipulated or controlled by the researcher.

• Independent variables are measured or observed and are affected by the dependent variables.

What are additive relationships?

• Additive relationships refer to relationships in which the sum of two or more quantities is always zero, regardless of the order in which they are added.

• Additive relationships refer to relationships in which the sum of two or more quantities is always the same, regardless of the order in which they are added.

• Additive relationships refer to relationships in which the sum of two or more quantities is always negative, regardless of the order in which they are added.

• Additive relationships refer to relationships in which the sum of two or more quantities is always different, regardless of the order in which they are added.

What are multiplicative relationships?

• Multiplicative relationships refer to the relationship between two or more variables where the change in one variable affects the change in the other variable by an inverse ratio.

• Multiplicative relationships refer to the relationship between two or more variables where the change in one variable affects the change in the other variable by a constant sum.

• Multiplicative relationships refer to the relationship between two or more variables where the change in one variable affects the change in the other variable by a constant factor or ratio.

• Multiplicative relationships refer to the relationship between two or more variables where the change in one variable has no effect on the change in the other variable.

How can you compare additive and multiplicative relationships?

• By counting the number of variables

• By examining the font size of the equation

• By examining how the relationship changes as the input variables increase or decrease.

• By looking at the color of the variables

If you were testing the time it took for objects of different sizes to reach the ground after being dropped from 30 feet in the air, which of these would be the DEPENDENT VARIABLE?

• The time it takes for each object to hit the ground.

• The size of each object.

• The type of object you use.

• The height you drop the object from
