issue:
1.It is always an individual who is the impetus for innovation; the details may be worked out by a team, but true innovation results from the enterprise and unique perception of an individual.
2.Rituals and ceremonies help define a culture. Without them, societies or groups of people have a diminished sense of who they are.
argu:
The following appeared in a letter to the editor of a Batavia newspaper.
"The department of agriculture in Batavia reports that the number of dairy farms throughout the country is now 25 percent greater than it was 10 years ago. During this same time period, however, the price of milk at the local Excello Food Market has increased from $1.50 to over $3.00 per gallon. To prevent farmers from continuing to receive excessive profits on an apparently increased supply of milk, the Batavia government should begin to regulate retail milk prices. Such regulation is necessary to ensure both lower prices and an adequate supply of milk for consumers."
数学总体挺简单的有二道图表题还挺绕的,图就不画了,描述一下,大家想一下
1. 图表一个柱状图,关于美国一个地区某年司机们被贴tickets的数目,总共发出的ticket是420张,横轴是ticket数目分别是1,2,3,4,5和6 or more,纵轴是得到每种数量ticket的司机数目我记得1的人数是52,2 的是35,3的是40,4的是22,5的是6,6以上的是8
第一小题问,好像是得到5张或者4张的司机有几个人,这个很简单,读图就可以了
第二小题问,得到6或者以上的人数的司机平均吃了几张tickets,这个要算出6以上一共发了多少tickets即420-52-2*35-3*40-4*22-5*6=60 再除以8=7.5,我开始就没看到写在图上面的420,想了好久
