Answer:

a) approximately 133 graduates

b) approximately 120°

Step-by-step explanation:

a) the number of graduates planning to continue studying :

= (37 1/2% + 12 1/2% + 16 2/3%) Ă— 200

[tex]=\frac{\left( 37\frac{1}{2} +12\frac{1}{2} +16\frac{2}{3} \right) }{100} \times200[/tex]

= (37.5 + 12.5 + 16.666666666667)Ă—2

= 133.333333333334

…………………………………

b) the measurement of the angle representing those who plan to work :

= (360Ă— 33 1/2)Ă·100

= (360Ă— 33.333333333333)Ă·100

=119.999999999999
