Question

If i have a 83% in class and get 95% on my summative which is

worth 30% what is my mark now? Pleaseeeee help.

Answer 1

86.6%

Explanation:

Since the summative is worth 30% of the grade, then the average of 83% is worth 70% of the grade.

70% of 83% + 30% of 90% = 0.7 × 83% + 0.3 × 95% = 58.1% + 28.5% = 86.6%

Answer: 86.6%

Answer 2

86.6%

Explanation:

new mark = (previous mark x weight of previous work) + (new mark x weight of new work)

In this case, your previous mark is 83%, and it is weighted at 70% (100% - 30%). Your new mark is 95%, and it is weighted at 30%. Substituting these values into the formula, we get:

new mark = (83% x 0.7) + (95% x 0.3)

new mark = 58.1% + 28.5%

new mark = 86.6%

So, your mark now is 86.6%
