# Course 2, Lesson 41, Using Formulas and Distributive Property

##### Rating:
(0)
Author: Hector Soto
##### Description:

1. Make sense of problems and persevere in solving them. 2. Look for and make use of structure. 3. Represent proportional relationships by equations. 4. Apply properties of operations as strategies to multiply and divide rational numbers. 5. Solve real-world and mathematical problems involving the four operations with rational numbers. 6. Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences. 7. Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.
