It is a down shift of 3.
Also written as (x, y-3)
What is the rest of the question
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The probability that the student knows the answer to the question is 
The probability that that the student will guess is 
The probability that that the student get the correct answer given that the student guessed is 
Here W denotes that the student gets the correct answer
Generally it a certain fact that if the student knows the answer he would get it correctly
So the probability the the student got answer given that he knows it is

Generally from Bayes theorem we can mathematically evaluate the probability that the student knows the answer given that he got it correctly as follows

Answer:
The total number of people at the stadium is 5,500
Step-by-step explanation:
2% of the fans in attendance were teenagers
if there were 110 teenagers at the football stadium
what is the total number of people at the stadium?
Let x = total number of people at the stadium
2% of x = 110
2/100 * x = 110
0.02x = 110
Divide both sides by 0.02
x = 110 / 0.02
= 5,500
x = 5,500
The total number of people at the stadium is 5,500
