Using the weighed mean formula, it is found that Mara's average for the course was of 68.6.

<h3>What is the weighed mean?</h3>

The weighed mean is given by the <u>sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights</u>.

In this problem, the weights are as follows:

  • A quiz has a weight of 1.
  • A test has a weight of 2.
  • The final examination has a weight of 4.

Hence, her weighed mean is given as follows:

M = \frac{2(65 + 62 + 60) + (61 + 96 + 80 + 89) + 4(65)}{6 + 4 + 4} = 68.6

Mara's average for the course was of 68.6.
