Minus 3x from both sides
2y=5-3x-y
add y to boht sides
3y=5-3x
divide both sides by 3
y=(5/3)-x

it's the same thing, there is no context, so it pushes for me to believe that the answer is the same
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?
Group of answer choices;

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.
Miley travel from home to school to work and back home again in 60 different ways
<em><u>Solution:</u></em>
<em><u>Miley walks to school by 1 of 3 routes in the morning</u></em>
So she chooses 1 route from 3 routes
Number of ways = 1 x 3 = 3 ways
<em><u>After school she chooses from 4 different routes to get to work</u></em>
So she has 4 different routes and she picks up 1
Number of ways = 1 x 4 = 4 ways
<em><u>When work is done she travels home by 1 of 5 different ways</u></em>
So she has 5 different routes and she picks up 1
Number of ways = 1 x 5 = 5 ways
<em><u>How many different routes can Miley travel from home to school to work and back home again?</u></em>
Total number of different ways = 3 ways x 4 ways x 5 ways
Total number of different ways = 3 x 4 x 5 = 60 ways
Thus Miley travel from home to school to work and back home again in 60 ways
