Answer: THAT IS RIGHT OK BYE MAN
Step-by-step explanation: OK BYE
1. Unless you have the total students, it would be D, because we don't know how many total students there are, so we don't know how many students 100% would be.
2. E. There are only 7% of the students who major in a medical area. So say out of 100 students, 7% of that would be 7 people, and 19% would be 19 people, and so on. So therefore, the least people are majoring in a medical field.
We have the triangle 30° - 60° - 90°.
The lenght of the sides are in proportion: 
0.5x22=11. To get answers like that, all you have to do is divide 11 by anything and then that number times the number you divided 11 by will give you the answer. So like 11 divided by 4 is 2.75. So 4x2.75=11.
