Answer:
No, it is not a fair game
Step-by-step explanation:
If it was a fair game, the expected value should be 0
If the expected value is 0, then the amount to be won and the amount to be lost is same and thus, the game does not tilt in favor of any of the competitors
But with an expected value of $2, there is actually a favor to one side

Answer:
0.03A + 0.03B = 800
A + B = 20000
Step-by-step explanation:
Let one part A of the total money invested with 3% interest = $A
Therefore, other part B of the money invested with 5% interest = $B
Interest = Principal amount × Rate of interest × Duration of investment
If the duration is 1 year,
Interest = Principal amount × Rate of interest
Return on part A = A × 0.03
Return on part B = B × 0.05
Total return = $800
So the equations will be,
0.03A + 0.03B = 800 -------(1)
Since, total money invested = $20000
Equation will be,
A + B = 20000 -------(2)
Answer:
18.85 mm.
7.73 mm^2.
Step-by-step explanation:
The side of the square = sqrt 36 = 6 mm.
Now this side = the diameter of the circle.
So the circumference of the circle = π * 6 = 18.85 mm.
The answer to the second part
= area of the square - area of the circle
= 36 - π *3^2
= 36 - 28.27
= 7.73 mm^2.
