Question 726918: A quiz consists of 10 multiple choice questions. Each question is marked either “right” or “wrong.” Each right answer gets 5 points, and 1 point is taken off for each wrong answer. What is the correlation between the score on the test and the number of right answers
Answer by fcabanski(1391)   (Show Source): You can put this solution on YOUR website!
Let x = the number of right answers. Then the number of wrong answers is 10-x


5 points for each right answer results in a score of 5x. -1 point for each wrong answer is -1*(10-x) = -10 + x.


The score is the sum of right and wrong answers: 5x + (-10 +x) = 6x-10
