This course introduces important algorithms and techniques of scientific computing, focussing on the area of numerical optimisation. The course will present both theoretical and practical aspects of the algorithms. The course is highly relevant to students from disciplines such as science, engineering or economics where skills in numerical computations are important.

A total of twelve hundred graduates of State Tech have gotten into medical school in the past several years. Of that number, one thousand earned scores of twenty-seven or higher on the MCAT and four hundred had GPAs that were 3.5 or higher. Moreover, three hundred had MCATs that were twenty-seven or higher and GPAs that were 3.5 or higher. What proportion of those twelve hundred graduates got into medical school with an MCAT lower than twenty-seven and a GPA below 3.5 ?

Let $A, B$, and $C$ be any three events defined on a sample space $S$. Let $N(A), N(B), N(C), N(A \cap$ $B), N(A \cap C), N(B \cap C)$, and $N(A \cap B \cap C)$ denote the numbers of outcomes in all the different intersections in which $A, B$, and $C$ are involved. Use a Venn diagram to suggest a formula for $N(A \cup B \cup C)$. [Hint: Start with the sum $N(A)+N(B)+N(C)$ and use the Venn diagram to identify the “adjustments” that need to be made to that sum before it can equal $N(A \cup B \cup C)$.] As a precedent, note that $N(A \cup B)=N(A)+N(B)-N(A \cap B)$. There, in the case of two events, subtracting $N(A \cap B)$ is the “adjustment.”

A poll conducted by a potential presidential candidate asked two questions: (1) Do you support the candidate’s position on taxes? and (2) Do you support the candidate’s position on homeland security? A total oftwelve hundred responses were received; six hundred said “yes” to the first question and four hundred said “yes” to the second. If three hundred respondents said “no” to the taxes question and “yes” to the homeland security question, how many said “yes” to the taxes question but “no” to the homeland security question?
For two events $A$ and $B$ defined on a sample space $S, N\left(A \cap B^C\right)=15, N\left(A^C \cap B\right)=50$, and $N(A \cap B)=2$. Given that $N(S)=120$, how many outcomes belong to neither $A$ nor $B$ ?

According to a family-oriented lobbying group, there is too much crude language and violence on television. Forty-two percent of the programs they screened had language they found offensive, $27 \%$ were too violent, and $10 \%$ were considered excessive in both language and violence. What percentage of programs did comply with the group’s standards?

Let $A$ and $B$ be any two events defined on $S$. Suppose that $P(A)=0.4, P(B)=0.5$, and $P(A \cap B)=$ 0.1 . What is the probability that $A$ or $B$ but not both occur?

## MATLAB代写

MATLAB 是一种用于技术计算的高性能语言。它将计算、可视化和编程集成在一个易于使用的环境中，其中问题和解决方案以熟悉的数学符号表示。典型用途包括：数学和计算算法开发建模、仿真和原型制作数据分析、探索和可视化科学和工程图形应用程序开发，包括图形用户界面构建MATLAB 是一个交互式系统，其基本数据元素是一个不需要维度的数组。这使您可以解决许多技术计算问题，尤其是那些具有矩阵和向量公式的问题，而只需用 C 或 Fortran 等标量非交互式语言编写程序所需的时间的一小部分。MATLAB 名称代表矩阵实验室。MATLAB 最初的编写目的是提供对由 LINPACK 和 EISPACK 项目开发的矩阵软件的轻松访问，这两个项目共同代表了矩阵计算软件的最新技术。MATLAB 经过多年的发展，得到了许多用户的投入。在大学环境中，它是数学、工程和科学入门和高级课程的标准教学工具。在工业领域，MATLAB 是高效研究、开发和分析的首选工具。MATLAB 具有一系列称为工具箱的特定于应用程序的解决方案。对于大多数 MATLAB 用户来说非常重要，工具箱允许您学习应用专业技术。工具箱是 MATLAB 函数（M 文件）的综合集合，可扩展 MATLAB 环境以解决特定类别的问题。可用工具箱的领域包括信号处理、控制系统、神经网络、模糊逻辑、小波、仿真等。
