Hello, thank you for taking the time to post your question!
A Credit Card Balance would be Numerical for data type because it would have a value/quantity assigned to it. Then level of measurement is Ratio because a balance of $0 signifies a complete absence of debt (a true zero point).
College Major is Categorical for data type (it’s a quality/category) and Nominal for level of measurement (the majors are simply names used for classification).
Then finally a Car’s Odometer Mileage Reading is Numerical for data type because it represents a value/quantity and Ratio for level of measurement because 0 miles means an absolute zero point of no distance traveled and you can also make meaningful ratio comparisons like 40,000 miles is twice as many miles as 20,000 miles
I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)
