The graph shows the relationship between the number of months different students practiced baseball and the number of games they
won:
Part A: What is the approximate y-intercept of the line of best fit and what does it represent?
Part B: Write the equation for the line of best fit in slope-intercept form and use it to predict the number of games that could be won after 13 months of practice. Show your work and include the points used to calculate the slope.

Answer: Expected value would be
Step-by-step explanation:
Since we have given that
Number of multiple choice question = 4
Number of true false questions = 2
Number of points for each multiple choice question = 3
Number of points for each true false question = 1
Number of choices in multiple choice = 5
Probability of getting correct answer in multiple choice question =
Probability of getting correct answer in true false question =
Expected value of the student's score on the test would be
Hence, expected value would be
