What are the best minors to pair with a math degree?
I've heard that tech and finance are good choices. If its tech, then what specific tech area is preferable? Are there any business minors would make a good choice? Are there other minors that would be good options?
Consider minors that truly interest you and offer an opportunity to develop skills in other areas that supplement your major. For example writing and communication skills, political science and information analysis skills, etc. Being able to speak to experiences and subjects you're truly passionate about and round out your knowledge tool kit will set you apart in interviews.
Any industry is looking for someone who can analyse data! You are on the right path. I think both business and computer science are really good routes to take. With any data analysis minor, you can go into a variety of industries and departments.
