Answer:
On average the carnival gain on each play
= 0.04 dollars
Step-by-step explanation:
Given that a pond contains 100 fish: 78 purple, 21 blue, and 1 silver.
Fish Purple Blue Silver total
Frequency 78 21 1 100
Prob 0.78 0.21 0.01 1
Revenue 0.4 0.8 13
game fee 0.65 0.65 0.65
Net revenue -0.25 0.15 12.35
Net Rev*Prob -0.195 0.0315 0.1235 -0.04
Thus we get per player expected net revenue is -0.04
This would be gain for Carnival
Hence On average the carnival gain on each play
= 0.04 dollars
Answer:
20% profit margin!
Step-by-step explanation:
Let suppose If the cost of a bucket is $100.
As the bucket is sold to 1/5 of the bucket cost.
i.e. 1/5 × 100 = $20
We know that 20% of 100 is 20.
i.e. 20/100 × 100 = 20
It mathematically means if the cost of the bucket was 100, and he sold at a profit equal to one - fifth of its cost price. It indicates that he earned a $20 profit. In other words, the person got a 20% profit percentage.
Note: I tried to take sample costs like $100 to make you understand as simple as I can.
Thus, if a bucket is sold at a profit equal to one - fifth of its cost price, the profit margin will always 20%, because if there are 5 parts of an object, 1 part makes the 20%.
I hope you get my point.
3:5 = 64cm
3x+5x= 64
8x=64
x=8
Therefore,
3x=8×3
=24
5x=8×5
=40
3x+5x=64cm
