Answer:Jarvis's class average is 75
Step-by-step explanation:
The total possible average score for the math course is 100
a) If the teacher rates homework at 10%, it means that the total possible score for homework
is 10/100 × 100 = 10
If his homework average is 93, then his score would be
(93×10)/100 = 9.3
b) If the teacher rates quizzes at 30%, it means that the total possible score for quizzes
is 30/100 × 100 = 30
If his quiz average is 82, then his score would be
(82×30)/100 = 24.6
c) If the teacher rates test at 40%, it means that the total possible score for quizzes
is 40/100 × 100 = 40
If his quiz average is 72, then his score would be
(72×40)/100 = 28.8
d) If the teacher rates final exam at 20%, it means that the total possible score for quizzes
is 20/100 × 100 = 20
If his final exam is 60, then his score would be
(60×20)/100 = 12
Jarvis's class average would be
9.3 + 24.6 + 28.8 + 12 = 74.7
Approximately 75
Answer:
Increase:
It will have increase when y>x
so, percentage of increase is
Decrease:
It will have decrease when x>y
so, percentage of decrease is
Step-by-step explanation:
Let's assume initial value as x
assume final value as y
Increase:
It will have increase when y>x
so, percentage of increase is
For example:
Initial value is 40
So, x=40
Final value is 50
so, y=50
now, we can find percentage in increase
Decrease:
It will have decrease when x>y
so, percentage of decrease is
For example:
Initial value is 50
So, x=50
Final value is 40
so, y=40
now, we can find percentage in decrease
