(0.9x 83)+(0.1 x 92) = ??
To calculate your average, you need to consider the weights assigned to each component. In this case, tests are worth 90% and quizzes are worth 10%.
First, calculate the weighted score for each component:
Test weighted score = test average * weight of tests = 83 * 0.9
Quiz weighted score = quiz average * weight of quizzes = 92 * 0.1
Next, add the weighted scores together to find your average:
Average = Test weighted score + Quiz weighted score = (83 * 0.9) + (92 * 0.1)
Let's calculate the values to find your average:
Test weighted score = 83 * 0.9 = 74.7
Quiz weighted score = 92 * 0.1 = 9.2
Now, add the weighted scores together:
Average = 74.7 + 9.2 = 83.9
Therefore, your average is 83.9.
