做闻 1）Investing in information technology such as hardwares/sofewares in firms that reply much on computers has proven results of maximizing the firm's profits. Every dollar will be paid back at the end.
Tips 1) new technology-new learning curve. The firm can only be fully functioned only if its employees can adapt to the new technology quickly. (Example can be Walmart's new system which keeps track of SKUs but employees need 6 months to learn how to use it). 2) Maximizing Profits? A new technology can be very expensive (Example can be Bloomberg, which costs a fortune but employees might end up using it for chatting with friends which is true haha) 3) frequent updates-hardwares/sofewares update frequently. If a firm wants to keep up with every update it might end up loosing money
2) Celebrities can be viewed as a uniquely defined group that can effectively address social problems beause of their high-profile status and resouces. 这个自由发挥吧，挺雷的我觉得哈哈
数学 1）有那道一个球orbit另外一个，给了需要44000hrs才能绕完，问两球圆心到圆心距离多少。（basically needs to know r+R+distance between surface)是ds题目 （1）给了转的速度，多少km一秒神马的， 不充分 （2） 给了两球surface之间的距离,還給了一個比例，反正不充分。最後選的e。。神馬都算不出來
4）有道题，insurance claim. 听我细细道来。。 A,B,C. If at least one claim, the total insurance paid to each claim will be the porportion of the limits. A limit=25,000 B=50,000 C=300,000. If the claim for all three is 7500 dollars, how much was paid for B?
Answer- You can get the ratio as A:B:C as 1:2:12, 15X=7500, x=500, so B=2*500=1000，这题偶确定
