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.

Answer:
y= 1/3x - 5/2 or D
Step-by-step explanation:
The way to convert counts into relative frequencies in a Two Way Relative Frequency Table is to divide the count by the total number of items
<h3>What is a Frequency Table?</h3>
This refers to the depiction of the number of times in which an event occurs in the form of a table.
Hence, when a two-way frequency table is used, it shows the visual representation of the possible relationship between different sets of data.
Please note that your question is incomplete as you did not provide the frequency table needed and also the trends and generalizations to find, so a general overview was given.

It's difficult to spot what kind of help is needed.
There's no variable in that equation whose value needs to be found.
It appears to be simply a statement, saying that the tangent of 36 degrees
is (3 and 3/7) .
As such, it's false, since the tangent of 36 degrees is roughly 0.7265 .
What exactly is the question ?
