Using atomic absorption, 0.0105 grams of copper sulfate pentahydrate were dissolved in a 100 mL volumetric flask and diluted to mark to make a 100 ug/mL solution. An unknown was made by placing an unknown amount of the above stock solution in a 100 mL volumetric flask and diluting to mark. The unknown gave an absorbance of 5.809 mg/L. How many mL of stock was used to make this unknown? The answer should be between 1 and 10 mL

A nutritionist wants to determine whether people who regularly drink one protein shake per day have different cholesterol levels than people in general. In the general population, cholesterol is normally distributed with u = 190 and o = 30. A person followed the protein shake regimen for two months and his cholesterol is 135. Use the 1% significance level to test the nutritionist's idea. (a) Use the five steps of hypothesis testing.

TITLE

PRIME FACTORIZATION USING AN ARRAY-BASED STACK

INTRODUCTION

This project revisits one of the problems in Project 2, and it will re-use a function within the solution developed there.

An integer is prime if it is divisible only by itself and 1. Every integer can be written as a product of prime numbers, unique except for their order, called its prime factorization. For example,

1776 = 37 x 3 x 2 x 2 x 2 x 2.

DESCRIPTION

Design, implement, document, and test an interactive program that reads positive integers from the terminal and writes their prime factorizations to the screen. The program should list the factors of each integer in decreasing order, as in the example above, and should terminate when the user enters 0 or a negative value.

INPUT

The program's input is positive integers, entered from the terminal, terminated by 0 or a negative value.

OUTPUT

The program's output consists of prompts for the input values and the input values' prime factorizations. It writes this output to the terminal.

ERRORS

The program can assume that its input is integers; it need not detect any errors.

EXAMPLE

A session with the program might look like this:

  Enter a positive integer (0 to stop): 1776
    Prime factors: 1776 = 37 x 3 x 2 x 2 x 2 x 2

  Enter a positive integer (0 to stop): 6463
    Prime factors: 6463 = 281 x 23

  Enter a positive integer (0 to stop): 349856
    Prime factors: 349856 = 29 x 29 x 13 x 2 x 2 x 2 x 2 x 2

  Enter a positive integer (0 to stop): 36423479
    Prime factors: 36423479 = 36423479

  Enter a positive integer (0 to stop): 1
    Prime factors: 1 = 1

  Enter a positive integer (0 to stop): 0
    

OTHER REQUIREMENTS

Implement a stack abstract data type in a class in which a typedef statement specifies the type of the stack's items. Use a sequential (array-based) stack implementation. As the program identifies prime factors, it should save them by pushing them onto a stack of integers provided by this class.

If d >= 2 is the smallest integer that divides an integer n, then d is prime. Therefore the program can identify prime factors (in ascending order) by repeatedly identifying the smallest factor of the target value and then dividing the target value by the factor. The program need not test that these smallest factors are prime or attempt to list only prime values; this will happen automatically.

Thus, to identify the prime factors of n, first find the smallest factor that divides n, push it onto the stack, and divide n by the factor. Then find the smallest factor of the new value of n; handle it the same way. Continue in this way until n = 1. Then pop and print the values until the stack is empty.

This scheme identifies prime factors in order of increasing magnitude; saving the values on the stack and then popping and printing them displays them in decreasing order, as specified.

HINT

Recall that you wrote a function that returns the smallest factor of its positive integer argument back in Project 2. You can re-use that function in this project.

HAND IN

See About Programming Assignments for a description of what to hand in: design document, user document, code, tests, and summary.

Question: If we wanted to report each integer's prime factors in increasing order, would the stack be necessary or helpful? Explain.

Project 2:

PRIME FACTORIZATION

The smallest nontrivial factor of a positive integer is necessarily prime. (Can you prove this?) Write a program that takes advantage of this fact in a recursive function that writes the prime factors of an integer to the terminal in ascending order.

A run of the program that exercises this function might look like this:

          Enter a positive integer: 5432
          The prime factors of 5432 are 2 2 2 7 97
    

Hint: Begin by writing a function that returns the smallest factor (greater than 1) of its positive integer argument. The recursive function will call this one.

QUESTION: How would you modify the function to print the prime factors in descending order?

What does it mean to get old?

When I was in my 20's I did not think about getting old. I would lift heavy weights - skip nights of sleep and eat whatever and how much of whatever I wanted.

IT was AWESOME... at the time.

Adulting is Hard.

Now I have type 2 diabetes because of my epigenetic diet choice interactions - angry joints (bad disks in back) and hurt feet. I have to be very careful of what I do or I can seriously hurt myself. Many of my peers from my college days are also in sad physical shape as well from how we were in the late 80s.

As far as Money goes - In college the major concern was finding enough money to buy bicycle parts - or maybe find a new roommate, or trying to date (ha!).

Last sememster I had to spend 12000 on re-plumbing our old house - and am about to spend another 50K or more on sending a kid to college.... but I can get whatever bicycle parts I want whenever I want.. but I don't because of aforementioned bills. If I had saved money when I was young - I would be able to retire in 5 years...

What does getting old mean to you?

Does that mean the same as Growing up?

Why can't young people (myself included) listen to old people and prep for when you are older?

1. It is desired to locate a control on a machine. The control will be located right in front of the worker at shoulder height. The worker population that is going to use the machine will include both male and female workers

1. Where should the control be located to include 90% of the population?
2. If the control is located at a reach distance of 82.5 cm, what percentile of the female population is being excluded (not being able to reach normally the control).

The random variable X follows a Poisson process with the given mean. Assuming mu equals 7, compute the following.

​(a) ​P(4​) ​
