Question 443279: The arithmetic mean of ten scores is 91. When the lowest score is dropped, the mean of the remaining nine scores is 94. What is the value of the score which was dropped? Answer by swincher4391(1107) (Show Source):
You can put this solution on YOUR website! When you add up the test scores, you would get 910.
Let x = the ten test scores.
Let y = the test score dropped.
Then x= 910
x-y = 846
