Arithmetic operations are inappropriate for a. large data sets. b. both categorical and quantitative data. c. quantitative data. d. categorical data.

The answer is d. categorical data

Step-by-step explanation: The reason is because categorical data are used to represent characteristics such as a person's state, religion, country, marital status, gender, etc.

Other names for categorical data are Qualitative data or Yes/No data.

The reason why Arithmetic operations can not be used for these kind of data is because the data are not numerical. For example, you can not add or subtract genders, neither can you multiply religions, and so on.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
