For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points through which the line passes:
We find the slope of the line:
Thus, the equation of the line is of the form:
We substitute one of the points and find b:
Finally, the equation is:
Answer:
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
