The bar chart shows the number of students with each letter grade in a certain professor's math classes. Since students need at
least a C for the grade to transfer, the professor groups all grades that are less than C into one category instead of grouping D's and F's separately.
How many fewer students have less than C's than have C's?
A 212
B 612
C 123
D 89

Answer with Step-by-step explanation:
Relationship between rotation and reflection:
In reflection, the pre-image gets flips across the same line.
whereas in rotation, the pre-image get spin around a point.
Rotations can be represented as two reflections i.e. the composition of reflections over two intersecting lines is always equal to rotation of that object.
In rotation, the object will get turned, this is turning some degree either clockwise or anti-clockwise.
Hence, rotation requires spinning and reflection requires flipping.
