1. 在清华镜像源的Anaconda页面(https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/)下载最新的Anaconda版本,选择适合自己操作系统的版本即可。
2. 安装Anaconda,在安装过程中可以按照提示一步步完成安装。
3. 安装完成后,在命令行中输入如下命令设置清华镜像源:
```
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --set show_channel_urls yes
```
4. 使用conda命令安装软件包时,可以使用清华镜像源加速下载:
```
conda install -i https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ [package name]
```
或者可以在Anaconda Navigator中也能够设置清华镜像源。打开Navigator,点击"Environments"选择需要修改的环境,点击"Channels",输入清华镜像源,点击"Add"即可。
安装完成后,就可以使用清华镜像源加速安装软件包了。做题
10. A company produces two types of products: A and B. A requires 3 labor hours and 2 machine hours to produce, while B requires 2 labor hours and 1 machine hour. A unit of A generates a profit of $10, while a unit of B generates a profit of $5. The company has 240 labor hours and 150 machine hours available each day. How many units of each product should the company produce to maximize its profit?
Solution:
Let x be the number of units of A and y be the number of units of B.
The objective function to be maximized is:
Profit = 10x + 5y
Subject to the following constraints:
3x + 2y ≤ 240 (labor hour constraint)
2x + y ≤ 150 (machine hour constraint)
x ≥ , y ≥
We can graph the feasible region for these constraints:
The shaded region is the feasible region, and the vertices are the corner points. We need to evaluate the objective function at each vertex to find the maximum profit.
Vertex (, ) yields a profit of $.
Vertex (80, ) yields a profit of $800.
Vertex (54, 72) yields a profit of $1,170.
Vertex (, 75) yields a profit of $375.
Therefore, the maximum profit is $1,170, which occurs when the company produces 54 units of A and 72 units of B.我可以继续什么?您需要什么帮助吗?请让我知道。
