网考网解析：
You can calculate this average score exactly the same way you would calculate a GPA--multiply each of the scores by the number of applicants with that score, add them all up, and divide the sum by 50. 10+48+63+14+8=143;143/50=2.86. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
