Using the combination formula, it is found that 2,220,075 committees can be formed.
The order in which the people are chosen is not important, hence, the <em>combination formula</em> is used to solve this question.
<h3>Combination formula:
</h3>
is the number of different combinations of x objects from a set of n elements, given by:
In this problem, 8 people are chosen from a set of 12 + 15 = 27, hence:

2,220,075 committees can be formed.

The answer is y= 3/4x - 4.
∠1 and ∠2 are alternate exterior angles where transversal BE crosses parallel lines AC and DF, therefore they are equal. ∠2 and ∠3 are opposite angles of a parallelogram, therefore they are equal.
... ∠1 = ∠2
... 3x -5 = 2x +15 . . . . substitute the given values
... x = 20 . . . . . . . . . . . add 5-2x
The measures of angles 1, 2, and 3 are 2·20+15 = 55 . . . degrees.
