1. Tris buffer

a. 100 mM Tris-HCl, pH 8.0

b. 100 mM Tris-HCl, pH 6.0

Make this buffer by dissolving an appropriate amount (which you must calculate using the formula weight) of solid Tris in APPROXIMATELY 80 mL of water. Use the Henderson-Hasselbalch equation to calculate how much 1 M HCl is needed to achieve the final pH?

Introduction: Mission to Mars

Your friend has been playing a new Mars Colony simulator nonstop! They are always talking about how cool it would be if they could be a on the first real-life mission to Mars! To amuse your friend, you have decided to create a series of programs about the possible first colony on Mars.

Problem: Where Can We Get the Best Deal? (marssupplier.c)

Now that we know how much fuel we need and how much equipment we can take, we need to determine which supplier will give us the best deal on what we need to purchase. We will poll a number of suppliers to see what kind of pricing they can give us and select the supplier who has the best deal.

In this program, we want to ask the user for information about suppliers. We can assume that there will be at least one supplier, but we will not know ahead of time how many suppliers there might be. After each supplier’s information, ask the user if there is another supplier to consider.

For each supplier, ask the user for the deal that the supplier is willing to offer. Keep track of the best possible deal and which supplier (identified as a number: 1, 2, 3, etc.) is offering it. After all the suppliers have been considered, tell the user which supplier offered the best deal.

Input Specification

  1. The user will use ‘Y’ to indicate there is at least one more supplier to consider.
  2. The user will use ‘N’ to indicate that there are no more suppliers to consider.
  3. Each suppliers’ price will be a positive real number.

Output Specification

For each supplier, prompt the user with:

What is the price for supplier #X?

To ask about additional suppliers, prompt the user with:

Is there another supplier to consider?

For the final print out, tell the user which supplier they should select, including the best price rounded to two decimal places:

Supplier #X had the best price at $Y.YY.

Output Samples

Below are some sample outputs of running the program. Note that these samples are NOT a comprehensive test. You should test your program with different data than is shown here based on the specifications given above. In the sample run below, for clarity and ease of reading, the user input is given in italics while the program output is in bold. (Note: When you actually run your program no bold or italics should appear at all. These are simply used in this description for clarity’s sake.)

Data and AI

Our customers will increasingly need to build their own AI to extract insights from the ever-increasing amount of data they collect — and we are investing to make Azure the best cloud for their comprehensive data estates. We are democratizing data science and AI with Azure Cognitive Services, Azure Machine Learning and data services such as Azure Cosmos DB — the first globally distributed, multi-model database — to help organizations of all sizes convert their data into insights and experiences for competitive advantage. In less than a year, Azure Cosmos DB has already exceeded $100 million in annualized revenue. Azure Database for MySQL and PostgreSQL makes it even easier to bring open source-powered applications to Azure, expanding our opportunity in this space. And we are seeing rapid customer adoption of Azure Databricks for data preparation, advanced analytics and machine learning scenarios. We are leading in the field of AI research, achieving human parity with object recognition, speech recognition, machine reading and — this year — language translation. But that is not enough. We are committed to translating these breakthroughs into toolsets our customers can use. More than 1 million developers have already used our Cognitive Services to quickly and easily create AI applications. Our Azure Bot Service has nearly 300,000 developers, and we are driving new advances in our underlying cloud infrastructure, building the world’s first AI supercomputer in Azure. Microsoft Translator brings AI-powered translation to developers where their data is, whether in the cloud or on the edge. Our pending acquisition of GitHub recognizes the increasingly vital role developers will play in value creation and growth across every industry, and will enable us to bring our tools and services to new audiences while enabling GitHub to grow and retain its developer-first ethos.

Gaming

We are pursuing an expansive opportunity in gaming — from the way games are created and distributed to how they are played and viewed — surpassing $10 billion in revenue this year for the first time. We are investing aggressively in content, community and cloud services across every endpoint to expand usage and deepen engagement with gamers. Xbox Live now has 57 million monthly active users, and we are investing in new services like Mixer — which blurs the line between watching and playing — and Game Pass, our new unlimited subscription service. The addition of five new gaming studios this year bolsters our first-party content development to support our fast-growing gaming services. And our acquisition of PlayFab accelerates our vision to build a world-class cloud platform for the gaming industry across mobile, PC and console. I’m excited about our opportunity in the fast-growing $100 billion gaming market and what’s to come.

3.

In an international ballroom dancing competition, competitors are scored by a panel of judges on a scale from 0 to 100. The final score for each couple is computed as the average of the scores from all the judges. However, if the number of judges is equal to or greater than 6, and the highest score is given by only one judge, that score is excluded from computing the average. The same applies to the lowest score.

  1. Write a method countOccurrences that returns the number of occurrences of a given target value in a given array. Complete the method countOccurrences below.

    Question 3(a)

    • /** Returns the number of times target occurs among the values
      * in the given array
      * @param scores an array of values
      * @param target the target value
      * @return the number of times target appears among the
      * values in scores
      */
      public static int countOccurrences(int[] scores, int target)

  2. Write a method findMaxAndMin that takes an array scores as a parameter and returns an array of length two, where the first element is the maximum value in scores and the second element is the minimum value in scores. Complete the method findMaxAndMin below.

    Question 3(b)

    • /** Returns an array of two elements in which
      * the first element is the maximum value in scores and
      * the second element is the minimum value in scores
      * Precondition: scores.length > 0; 0 <= scores[k] <= 100
      */
      public static int[] findMaxAndMin(int[] scores)

  3. Write a method averageScore that takes an array scores as a parameter and computes and returns the average score. However, if the size of the array scores is 6 or greater, and the maximum value occurs only once in the array, that value is excluded from computing the average. The same is done for the minimum value.

    In writing this method, assume that the methods countOccurrences from Part (a) and findMaxAndMin from Part (b) work as specified, regardless of what you wrote there. You may not receive full credit if instead of calling these methods you write equivalent code here. Complete the method averageScore below.

    Question 3(c)

    • /** Returns the average of the values in scores. However,
      * if the size of the array scores is not less than 6 and
      * the largest value occurs only once in scores, that value
      * is excluded from computing the average; the same for
      * the smallest value.
      * Precondition: scores.length >= 3; 0 <= scores[k] <= 100
      */
      public static double averageScore(int[] scores)
