Using the combination formula, it is found that there are 84 ways to choose the three tiles.
The order in which the tiles are chosen is not important, hence the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:

Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative. Take a look at some examples. The distance from 5 to 0 is 5 units.
Ok since the amount in the bank account will decrease the rate of change is negative and the bank account itself is positive. And the rate of change is 145 and the constant or y - intercept is 369. As a linear equation it would look like y = -145x + 369.
The answer is 3 because 3 cubed is 27
