This curve here with the square shows you how many millions of vaccine doses were distributed across the U.S.
这个带方形的曲线图显示了,在美国数以百万计的,疫苗是如何使用的

Right, I'm hoping I the grades in order, otherwise it's going to ruin my curve at the end of the year.
我希望我成绩尽量好,要不我一年的努力就白费了
-
I should be able to do nice bell-shaped curves, but it's harder than it looks standing up here; so that's your bell-shaped curve.
我还是挺擅长画钟型曲线的,但站着画真的不太容易,这就是钟型曲线
-
That's the way we do it, no grading on a curve.
我们就是这样做的，打分没有余地。

Then he knows it's going to go up, it's going to curve, follow some kind of parabola, then his hands go there to receive it.
所以他就知道,这颗糖会先向上,再向下,沿着某条抛物线运动,然后他就能判断在哪里接住糖

If it's a reversible process, we know the work is the area under the curve.
对可逆过程，功等于p-V图上。
-
If you run these curves only on non-smokers you get rid of that J at the end of the curve and you get pretty much a function that's to the right of the curve here.
如果仅在不吸烟人群中做统计,那么左末端就不会出现J形曲线,而是会得到一条,从左到右逐渐上升的完美的函数曲线

It's a demand curve. Thank you; it's a demand curve. That was the demand.
它叫需求曲线,感谢你的回答
-
It's a bell-shaped curve that looks about like that.
大概就是一条这样的钟形曲线
-
It's where the marginal cost and the demand curve intersects.
边际成本与需求曲线的交点处
-
That's the curve that I got out.
得到了这条曲线。
-
W2 So in this case, it's the amount of work is the area under that curve. And in this case here, the amount of work is bigger, w2 is bigger and it's the area under this curve.
这是路径2做的功,比W1要大，现在假设,我把这两条路径结合起来。
-
Both times there's a demand curve out there.
两者都有需求曲线
-
But it turns out that if you make the voters distributed more realistically, let's say like on a bell-curve shape, it makes actually no difference to the result at all.
但事实上,就算我们让选民分布更符合实际情况,比如说是按钟形分布的,但这实际上对结果没有什么影响
-
That's a bell-shaped curve, but it's centered exactly on .2.
这是条钟形曲线,它关于x=0.2对称
-
Let me finish the picture here; here's my demand curve, here's my constant marginal cost at c, and I want to use this picture on the left now to figure out what the monopoly quantity is.
先把图画完,这条是需求曲线,这个是边际成本常量c,下面我们通过左边的图像,来找出垄断产量
-
That's not literally true. I'm going to squeeze it a bit, I'm going to curve it a bit, so actually slightly fewer than a sixth will get straight A's, and fewer than a sixth will get C's and below.
但我可能稍微压缩下分数段,我会让分数段更有弹性,实际上略少于六分之一的人会得到A,略少于六分之一会得到C
