If the Diameter Is 4 inches then the radius will be 2 inches!
Hope I Helped!
The answer is A or c I’m probs wrong
20/5
4x/x adding 10 to each
4x+10/x+10 =2
Multiple x+10 to each side
4x+10=2x+20
Then subtract and get
2x=10
Divide
X=5
Now plug it back in
20/5
Answer:
The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.
1360/200
13.6/2
6.8
It is a finite decimal, but if you want repeating, there are zeroes that follow, like so:
6.8000000000000 . . . (and on to infinity)
