Question

The table below shows the number of classes offered at a fine arts school in New York. Fine Arts Classes

Answer 1

We have the following:

A.

To know the proportion of any type of class, we must divide the specific quantity of that class by the sum of all the classes.

As follows (music) :

`(40)/(45+30+40+35)=(40)/(150)=(4)/(15)\rightarrow4\colon15`

B.

We know that a circle in total has 360 °, so to know the corresponding angle of music we must multiply that total by the proportion calculated previously

`360\cdot(4)/(15)=96`

Therefore the corresponding angle is 96 degrees
