AWa：
The following appeared as part of an annual report sent to stockholders by Olympic Foods, a processor of frozen foods:
“Over time, the costs of processing go down because as organizations learn how to do things better, they become more efficient. In color film processing, for example, the cost of a 3-by-5-inch print fell from 50 cents for five-day service in 1970 to 20 cents for one-day service in 1984. The same principle applies to the processing of food. And since Olympic Foods will soon celebrate its 25th birthday, we can expect that our long experience will enable us to minimize costs and thus maximize profits.”
鼠穴
做到半圆里有2个正方形，半径2根号5，基金有
DS题 一个数是奇数的条件：1 N^4末尾不是1, 2 N^8和N^9末尾相同
更正鼠穴基金:
第68 题干是对的 条件是
1 3N为偶数 2 N+2 为偶数
107是够主记得是对的 9.55
249 出现变体 条件2变为y/2 roundto 1
297 够主漏了一个6
应该是6^(-12)*2^(-6)*3^(-2)*6^n
ans应该没错
补充一个PS：
有红球编号1到8， 蓝球编号1到8
红的放在一个盒子里，蓝球放在一个盒子里。从两个盒子各取一个球，问红球数字与蓝球数字一样的概率
没上7 语文就不说了哈
大家复习加油
