(ii) 3% of students failed all three courses, 12% failed economics and mathematics, 9% in math and business, and 10% in econ and business. In other words, the students in these groups failed at least the two mentioned courses. Then 12% - 3% = 9% failed only econ and math <em>but not</em> business; 9% - 3% = 6% failed math and business <em>but not</em> econ; and 10% - 3% = 7% failed econ and business <em>but not</em> math. These groups are mutually exclusive, so the total percentage of students that failed exactly two courses is (ii) 9% + 6% + 7% = 22%.
32% failed econ, which means 32% - 12% - 10% + 3% = 13% failed <em>only</em> econ. Similarly, 46% failed business, so 46% - 9% - 10% + 3% = 30% failed <em>only</em> business. But we don't know how many students failed math, so we can't determine how many failed <em>only</em> math... And consequently we can't determine the proportion of students that make up the other categories.
Coterminal angle is an angle which has the same initial and terminal side of the original angle. It can be found by adding or subtracting 360deg.
A positive angle less than 360 that is coterminal with -85 is = -85 + 360
= 275 degree
Answer:
Step-by-step explanation:
Step-by-step explanation:
That region can be described as an infinit plate with a thickness of z=6
- Is infinit because is not limited in X and Y axis
- Is a plate because (in rectangular coordinates) its limited in one axis and not the others.
- Has a thickness of z=6 due to Z being limited between 0 and 6
