Question

directions: determine whether the relationship has a positive, negative, or no relationship. 1. running speed versus time to complete a marathon. 2. birth year versus birth weight. 3. population of a state versus number of seats in the house of representatives. 4. latitude versus average annual temperature.

Explanation:

Step1: Analyze running speed and marathon completion time

As running speed increases, the time to complete a marathon decreases. So, there is a negative relationship.

Step2: Analyze birth year and birth weight

There is no inherent connection between the year a person is born and their birth weight. So, there is no relationship.

Step3: Analyze state population and House seats

As the population of a state increases, the number of seats in the House of Representatives (based on population - based apportionment) also increases. So, there is a positive relationship.

Step4: Analyze latitude and average annual temperature

As latitude increases (moving away from the equator), the average annual temperature generally decreases. So, there is a negative relationship.

Answer:

1. Negative relationship
2. No relationship
3. Positive relationship
4. Negative relationship
