(c) calculating the weighted average of the primary and secondary material properties

Explanation:

Composite materials are materials that are made of two or more materials that have vastly different properties. This results in the property of the composite material to be superior the properties of the individual components.

The rule of mixtures states that the composite's weighted average of the property values of the components measures the property value. The weighting is done by comparing the components which are present in the composite.
