AWA AI: a nation should maintain a competitive educational system to ensure its economic success. AA: 44. The following is part of a business plan created by the management of the Megamart grocery store. “Our total sales have increased this year by 20 percent since we added a pharmacy section to our grocery store. Clearly, the customer’s main concern is the convenience afforded by one-stop shopping. The surest way to increase our profits over the next couple of years, therefore, is to add a clothing department along with an automotive supplies and repair shop. We should also plan to continue adding new departments and services, such as a restaurant and a garden shop, in subsequent years. Being the only store in the area that offers such a range of services will give us a competitive advantage over other local stores.” Math: 有卡车装沙子占多少比例那题 求平方根的近似值，0.8那道 有一个题我还记得，大概是两个set，A和B，从B中拿一个数到A，问没拿之前这两个set里面谁的平均值大 A. 拿之后两个set的median都没变 拿之后两个set的median都没变
