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.

56,000÷2 = 28,000
14,000÷2 = 7,000
28,000/7,000 = 28/7
28 ÷ 7 = 4

7 ÷7 = 1

Hope this helps!
10 kilometers is equal to a little over 6 miles. And 6 > 5, therefore 10 kilometers is your answer.
Answer:
The slope is 4, and the y-intercept is Negative five-halves
Step-by-step explanation:
we have
This is the equation of the line in standard form
Convert the equation in slope intercept form
where
m is the slope
b is the y-intercept
Isolate the variable y
Subtract 8x both sides
Divide by -2 both sides
therefore
