The square footage of a house discrete or continuous? A. The random variable is discrete. The possible values are a equals 1 comma 2 comma 3 comma B. The random variable is discrete. The possible values are a greater than 0. C. The random variable is continuous. The possible values are a equals 1 comma 2 comma 3 comma D. The random variable is continuous. The possible values are a greater than 0.

The random variable is continuous. The possible values are a greater than 0.

Step-by-step explanation:

We have to identify if "Square Footage of a house" is a discrete variable or a random variable. For this first we need to understand the difference between both type of variables.

Discrete Variable:

A discrete variable can only take specific value e.g. number of people in a hotel which can take only whole number values like 15, 43, 155 etc. A discrete variable is counted. Examples are: Number of people, number of books etc

Continuous Variable:

A continuous variable can take all the values within its specific range. For example, weight of a person. Weight can take any value greater than 0. Weight can be in decimals, can be in integers. A continuous variable is always measured.

The given variable: "Square Footage of a house" can take any value greater than 0, there is no limit to it. "Square Footage of a house" is always measured.

Based on this we can conclude that "Square Footage of a house" is a Continuous variable and can take all values greater than 0.

Number of miles Leeann rode on Day 1 =6.75 miles

Number of miles Leeann rode on Day 2=12.4 miles

The question is asking us to find the total number of miles she rode in all.

Number of miles Leeann rode on Day 1 and day 2 = 6.75+12.4=19.15 miles.

Number of miles she ride her bike both days is 19.5 miles.
