另外,在另一端,我们有原子序数较大的元素,这些元素有着较高的平均化合价和电子能。
So, the most connected one would be the one for whom the quarter million are, on average, the most connected to.
连接性最强的那个,他和这25万演员,连接的平均度数最小。
So, sometimes people get confused when they're solving problems and call the amplitude this distance all the way from the max to the min but it's only half of that because we're only going back to the average level.
解题的时候会弄错,把这个从,最大值到最小值的距离,叫做幅值,但实际上,只有它的一半,只是它和平均值的差距。
And then I could also do a Gaussian one here, with the mean of and the standard deviation of volatility divided by 2.
然后我在这里再写一个高斯分布的函数,它的浮动值的平均值和,标准偏差值都除了2。
I computed the average return on stocks over that time period and I computed the average return on bonds over that time period.
我计算了那个时间段的股票平均收益率,和债券平均收益率。
And up in the other extreme are elements with very high average valence electron energy.
和那些特别元素,它们具有很好的平均价电子能。
This would be an average adult male, 30 years old, the average height and weight, and surface area and temperature, and lots of characteristics of an average person.
包括普通成年男性,三十岁,平均身高和体重,平均表面积和体温,还有许多其他数据
I thought similar to Chris actually and I also thought that if we got two-thirds and everyone was choosing numbers in between 1 and 100 ends up with 33, would be around the number.
实际上我的想法和克里斯的相近,我也在想我们得选平均数的2/3,每个人都在1到100中选择的话,最后结果可能是33,会接近于平均数的2/3
For example, if you started here and you did all this and you came back here, the average velocity would be zero, because you start and end at the same value of x, you get something; 0 divided by time will still be 0.
例如,如果你从这里开始运动,经过这个过程又回到这里,平均速度就是0,因为初态和末态的位移相同,你得到了什么呢,0除以时间还是0
this is why Maslow said human nature and human potential has been sold short, when we only study the average.
这就是为什么Maslow说人性,和人的潜能会被削弱,如果我们只研究平均水平的话。
I would expect, whether you're a Red Sox fan or not, you to be able to look at a list of different pitchers and their average velocity for their fastball, and tell me who has the longest or the shortest wavelength.
无论你是否是一个红袜队球迷,我预想你会看到一系列,不同的投手和他们,投出快球的平均速度,告诉我谁有最长的,或者最短的波长。
Well, let's do the smoke test number one: is the mean more or less what we expected?
好了,让我们先做1号发烟测试:,这个平均值是和我们想要的答案差不多吗?
It could be normal, everything, that would be a Gaussian, where if you recall there was a mean, and a standard deviation, and most values were going to be close to the mean.
可能是正态分布,也就是高斯分布,只要有平均值和标准偏差值,你就可以进行调用,大部分的值都是集中在平均值附近的。
the winner is the person whose number is closest to 2/3 times the average The winner will win $5 minus the difference in pennies between her choice and that two-thirds of the average."
所选数字最接近2/3倍平均数人是赢家,赢家的奖金是5美元减去,所选数和平均数三分之二之差的百分数
I computed the returns on the stocks, bonds, and oil for every year from 1983 and I computed the average returns, which I take as the expected returns, I took the standard deviations, and I took the covariance.
我计算了从1983年以来每年的股票,债券和石油的收益,从而得出平均收益率,这些平均收益率作为预期收益率,然后算得标准差及协方差。
So even if, on average, the stock is expected to not move at all from where it starts, some stocks will be expected to just trundle along without much change, not very volatile.
所以即使平均而言,股票应该是不会,和开盘的时候有什么区别,有一些股票可能会,没什么变化,不是很反复无常。
Cl We know that because the sulfur and the chlorine in the oxygen have different average valence electron energies, they'll have different electron affinities.
我们都知道因为S和,在氧气中,具有不同的平均价电子能,所以他们的电子亲和力也不同。
They would say there is a low correlation between SAT scores and grade point averages in college, or maybe it's a high correlation.
媒体会说,SAT成绩,和大学里的平均学分相关性很低,或相关性很高
So, the average is found by taking two instants in time, say t1 and later t2, and you find out where it was at t2 minus where it was at t1 and divide by the time.
平均速度就是取两个时刻,比如t1和之后的t2,用t2时刻的位移,减去t1时刻的位移,再除以这段时间
