Emma's grades are the following along with the weight of each assignment:
7/10 (10%)
5/10 (10%)
26.5/47 (20%)
22.5/50. (20%)
Hw worth (10%) not yet added
Final worth (40%) not yet added.
What is her current grade before the hw and final?
Those add up to 110%. Perhaps, but probably typo.
oh sorry I meant:
7/10 & 5/10(10%)
26.5/47 (20%)
22.5/50. (20%)
Hw worth (10%) not yet added
Final worth (40%) not yet added.
To calculate Emma's current grade before the homework (worth 10%) and the final exam (worth 40%), you need to calculate her overall average based on the weighted grades.
Let's break down the calculations step by step:
1. Convert each letter grade into a decimal by dividing the numerator by the denominator:
- 7/10 = 0.7
- 5/10 = 0.5
- 26.5/47 ≈ 0.564
- 22.5/50 = 0.45
2. Calculate the weighted average of the assignments:
- Multiply each grade by its respective weight:
- 0.7 (10%) = 0.07
- 0.5 (10%) = 0.05
- 0.564 (20%) = 0.1128
- 0.45 (20%) = 0.09
3. Add up the weighted grades:
- 0.07 + 0.05 + 0.1128 + 0.09 = 0.3228
4. Calculate the current grade without homework and the final:
- The sum of the weighted grades represents the current grade before adding the homework and final exam.
So, Emma's current grade before the homework and final is approximately 0.3228 (or 32.28%).
