Answer: I think It's D
Step-by-step explanation: Comment if im right or wrong please
<span>The number of ways to permute three correct answers among five questions is 5Choose3 which is 5!/(3!*2!) which equals 10.
We must then have the correct answer three times which happens .25 of the time, and two wrong answers 75 of the time.
So the probability is 10*0.25^3*.75^2 which is 0.087890625 or roughly an 8.8% chance.</span>
Answer:
30
70
5 (5 nickels for every 1 quarter)
This depends on the equation.
Here we are give the value for π and Diameter of the circle fence
π=3.14
Diameter = 16
Radius = Diameter/2
2πr = 2(3.14)(8)
Circumference = 50.27
Now to fine the square fence length so we do 16*4 = 64
64-50.27 = 13.73 in
Therefore, the square fence is 13.73 inches longer than the circle fence
