1 yard = 3 feet
1 minute = 60 seconds
Multiply 32 feet per second by 60 to find feet per minute:
32 x 60 = 1920 feet per minute.
Divide total feet per minute by 3 feet to find yards per minute:
1920 / 3 =640 yards per minute.
Two solutions exist,
2(x - 1) = 8
2x - 2 = 8
2x = 10
x = 5
&
2(x + 1) = 8
2x + 2 = 8
2x = 6
x = 3
the two solutions are 5 and 3
Amount of points don't matter what is the question lets see if I can help
The speed of the water in the 3 feet radius is 25 feet per second.
Well this is a more complicated question than it may seem.
The laws of probability are based on observations whose number is very large or actually as the number of observations approaches infinity.
So on the one hand, you should be concerned that you get 0/8 to land on 3.
However, 42/500 land on 3 so your ratio has improved.
It's not near 125 but it's also not 0.
If it remained at 0, you would begin to be concerned and rightly so.
Perhaps if you did 5000, you would be less concerned as the ratio improved and got closer to 1/4 of the observations.
So at this point I don't think you have enough information to determine that the spinner is unfair.
