You have an 81.3. To find this you take your average for the parts, say for example the tests and multiply it times the percentage as a decimal. So for the tests it would be 84.20*0.40
So out of 40 points possible of the 100 final points you got 33.68. You would do this for all the sections and add the points together
(84.20*0.40)+(61.75*0.35)+(99.57*0.15)
Answer:
The earning would be approximately 79.29 % in the final exam
Step-by-step explanation:
Given,
In class grade the percentage of homework = 40 % = 0.40 ,
Percentage of quizzes = 25 % = 0.25,
Percentage of final exam = 35 %=0.35,
Also, there is an earning of 95% in homework and 84% in quizzes entering the final exam,
⇒ Earning in homework = 95 % of 0.40,
And, earning in quizzes = 84 % of 0.25
Let x be the percentage do you have to earn in the final in order to have an 87% overall percentage,
[tex]\implies 95 \%\text{ of }0.40+84\%\text{ of }0.25 + x\%\text{ of }0.35=87\%[/tex]
[tex]59.25+0.35x=87[/tex]
[tex]0.35x=27.75[/tex]
[tex]\implies x = 79.2857142857\approx 79.29\%[/tex]
Hence, the earning would be approximately 79.29 % in the final exam in order to have an 87% overall percentage.
