Solve the problem. 1/1 Feedback In baseball, a pitcher's earned -run average (the average number of runs given up every 9 innings, or 1 game) is given by E=9· , where n is the number of earned runs allowed and i is the number of innings pitched. Suppose we fix the number of earned runs allowed at 5 and let i vary. Find E(i). Student Response A. ∞ B. 15 C. 5 D. 0 Score: 9. Find the limit, if it exists. 1/1 Feedback Student Response A.
