Due to the bad weather, cotton yield poer mu is very low this year.

由于天气，年棉花的亩产量很低。

And each began cohabitating with humans at different times in our evolutionary history. For example, " Mus musculus domesticus."

在我们进化史的同时期，每种老鼠都开始了与人类共存的生活。比如, “家鼠。”

" Mus musculus domesticus" .It began raiding human pantries around 12,000 years ago.

“家栖小家鼠”。它们大约在12000年前开始侵扰人类的储藏室。

" Now me mus tuddy my lessin, " went on the funny little thing.

“现在我必须学习， ” 那个有趣的小东西继续说道。

Remember, our true mean is this, that the Greek letter mu is our true mean.

记住，我们的真正均值是这个，希腊字母μ代表我们的真正均值。

And let's see, minus 2 times mu-- sorry, that mu doesn't look good.

然后我们看，减去2乘均值——抱歉，那个均值的符号看起来。

So, narcotics and endorphins probably activate mu opioid receptors in different ways.

所，麻醉药物和内啡肽可能同的方式激活μ-阿片受体。

" mu" " k" times " Fn" and the " mu" " k"

" mu" " k" 乘 " Fn" 并且 " mu" " k" 将是 0.

So minus mu K so the force of friction--- I'll just put force of friction.

所减去 mu K 所摩擦力 --- 我只输入摩擦力。

The parameter and the data x bar and mu play symmetric roles.

参数和数据 x bar 和 mu 扮演称角色。

One mu equals roughly 0.067 hectares.

一亩大约等于0.067公顷。

MU stands for Most Obvious Objection.

MU代表最明显的反意见。

The force of friction is always mu K FN.

摩擦力始终为 mu K FN。

Now we could measure its mu, which is the magnetic permeability of that object or of that material.

现在我们可测量它的磁导率，也就是那个物体或那种材料的磁导率。

And so, if I wanted to learn mu, all I need to know is X bar.

所, 如果我想学习mu, 我所需要知道的就是X bar。

So I know the density, pz, given mu and sigma squared.

所我知道密度, pz, 给定mu和sigma平方。

So I could end up writing down F X bar given mu in sigma squared.

因此, 我最终可写下 F X bar given mu in sigma squared。

Then you have x sub i times minus mu.

然后你有x下标i乘减去均值μ。

Edit, Undo, minus 2 times mu times the sum from i is equal to 1 to n of xi.

编辑，撤销，减去2倍均值乘从i等于1到n的xi之和。

And then you have minus mu times x sub i.

然后你有减去mu乘x下标i。
