※ 引述《nephology (事情是怎麽发生的)》之铭言:
: 1.
: d=5.03894 and (d) is the decimal expression for d rounded
: to the nearest thousandth
: The number of decimal 4
: places where d and (d)
: differ
: 答案是右边比左边大,不大懂题义
这题应该是说 d=5.03894
(d)=d在千分位的四舍五入=5.039
故d<(d) 右边比左边大
有错请指正^^"
: 2.
: If the average (arithmetic mean) of 5 consecutive integers is
: 12, what is the sum of the least and greatest of the 5 integers?
: (A) 24 (B) 14 (C) 12 (D) 11 (E) 10
: 答案是 (A)
