Find attached the graph and a table with some important points.
Note that every point of the graph is the extreme of a vector whose radius is r and angle is theta.
Answer: one fourth
Fourth is a word that used to describe a number value of 1/4. To answer this question, you need to change the number you got (3/12) into x/4 form. To convert 12 into 4, then you need to divide the numerator and denominator with 3. The equation would be (3/3)/(12/3)= 1/4.
To determine how much fourth the number has, you need to divide the result with 1/4. The calculation would be: (1/4)/ (1/4)= one fourth
The complete question is;
A surgeon performed two types of surgeries to treat large kidney stones and small kidney stones. Treatment A on large stones was successful 73% of the time, but on small stones it was successful 93% of the time. Treatment B was successful on large stones 69% of the time, but on small stones it was successful 87% of the time. The overall report stated treatment B was more successful. What may make this claim possible?

Simpson's Paradox
Answer:
Correct Option is Simpson's Paradox
Step-by-step explanation:
Looking at all the options, The correct option is Simpson's Paradox because the concept of the other options don't depict the paradox displayed in the question.
Now, Simpson's paradox, is simply a phenomenon in probability and statistics, whereby a trend appears in several different groups of data but will disappear or reverse when these groups are combined. This result is often encountered in many areas of statistics and is very problematic especially when frequency data is given causal interpretations. The paradox can be resolved when causal relations are appropriately addressed in the statistical modeling.
Now, in this question, it concluded that treatment B was more successful than treatment A without considering the conditions under which both treatments were carried out neither did it consider the severity of cases of patients involved in the treatment.
209,767 rounded to the nearest hundred thousand (Or nearest 100,000) is 200,000.
