ok I have a math quiz for you Engineers out there...

if you took a 5part test with varying percentages on each part and recieved the following grades, what is lowest possible score you could recieve as an overall grade?

Shermie, please dont answer....at 5pm today I will post the answer!!

Test Results
Part1 - 71% and is worth between 22% to 28%
Part2 - 80% and is worth between 12% to 18%
Part3 - 78% and is worth between 32% to 38%
Part4 - 79% and is worth between 8% to 12%
Part5 - 76% and is worth between 12% to 18%

 

I know.

 

76?

i don't have an engineering degree just a 1 minute guess...

 

Is this a trick question or should it be that easy.

 

glad we have some participation in the club....check back after 5p for the answer

Lyndon, I know you saw the question...you better come up with an answer!!

 

ONE HINT!!!

Make no assumptions!!!

 

the answer is
E) 76

 

id say 76.

 

65.62

 

71*.22+80*.12+78*.32+79*.08+76*.12
=15.62+9.6+24.96+6.32+9.12
=65.62

 

lowest percentage on each part times the grade you got on each part
sum them together and you will get your lowest grade



god i hate school

 

thats incorrect becuase the percentages weighted dont add up to 100%....

i still say 76

 

o well
guess im wrong. guess i better go back to studyin for my final tomorrow

 

u just said what they said....i challenge you to show your work!!!

 

77.35
