I need help with a Mathematics question. All explanations and answers will be used to help me learn.

Complete your Week 5 discussion prompt:

Teach your classmates the process to find the domain of  rational function. Illustrate the concept with two examples, one of which requires factoring. Please include both set notation and interval notation as part of your teaching. Remember that teaching requires detailed explanation, as well as the actual math notation.

write a nul hypothesis,run analysis either by using data analysis and the two sample or by comparing the two confidence intervals.Interpret data to determine if the resting heart rate is the same

I am expecting two different documents the first one for task 1 and the scened one for task 2. I have attached documents for task 1 please read and follow the instructions for task 1. For Task 2, you will need to write a response to the file that I have attached. I am expecting 250 to 350 words for task 1.

   Competency

   Describe the data using the measures of central tendency and measures of variability.

   Scenario (information repeated for deliverable 01, 03, and 04)
   A major client of your company is interested in the salary distributions of jobs in the state of Minnesota that range from $30,000 to $200,000 per year. As a Business Analyst, your boss asks you to research and analyze the salary distributions. You are given a spreadsheet that contains the following information:

   • A listing of the jobs by title
   • The salary (in dollars) for each job

   The client needs the preliminary findings by the end of the day. Your boss asks you to first compute some basic statistics and then analyze the results in the four questions given in the Excel spreadsheet.

   Background information on the Data

   The data set in the spreadsheet consists of 364 records that you will be analyzing from the Bureau of Labor Statistics. The data set contains a listing of several jobs titles with yearly salaries ranging from approximately $30,000 to $200,000 for the state of Minnesota.

   What to Submit

   Your boss wants you to submit the spreadsheet with the completed calculations, answers, and analysis.

Help with assignment!

Important key details:

– my project will be helping the homeless providing them with sanitary/hygiene products/non perishable food/ clean under garments (socks underwear bras) etc.

– my organization will take place in San Diego Ca.

1. Watch the lecture by Dr. Gloria Ladson-Billings. It is about one hour and twenty minutes. Write a half-page single space reflection.

2. In the climate change problem there was an inherent feedback loop that, when the de-regulation parameter changed, the system was bumped into a new normal (which is not a better new normal for the planet). As you saw, this new normal is not easily reversed. This phenomenon is known as hysteresis, which represents the history dependence of physical systems. If you push on something (or change a parameter in the system), it will yield: when you release (or reset the parameter), does it spring back completely? If it doesn’t, it is exhibiting hysteresis.

Pick one of three contexts below and discuss how the context might reflect a similar situation where a parameter change could bump the system into a new normal, one that is not easily reversed. Create a hypothetical phase line and explain how the phase line describes the context.

Context 1: The parameter k is related to the ratio of counselors to cops and the dependent variable is high school graduation for historically marginalized students.

Context 2: The parameter k is related to shifting funding from law enforcement to social programs (housing security, food security) and the dependent variable incarceration rate of historically marginalized groups.

Context 3: (Un)employment in times of economic downturn. See Wikipedia entry: 7.1 Permanently higher unemployment

A Linear Equation is a rule that assigns to each number x on the x-axis exactly one number y on the y – axis so that the ordered pairs (x,y) form a line. We call y the Dependent Variable and we call x the Independent Variable because the value assigned to y by the linear equation will depend on the value selected for x.

Now consider this scenario: we can burn 4 calories by walking 100 steps. The linear equation modeling this scenario is C=0.04*S where C is the dependent variable and S is the independent variable. Here, C represents calories burned for some number of steps S walked.

You will create a new linear model that shows the amount of calories burned in a given day during some activity you choose, compensating for food intake. Produce a model with a reasonable rate of calorie burn for walking, running, or some other activity, and account for a daily calorie intake between 1200 and 3000 calories. Be sure to describe the detailed scenario for which your equation models. Conclude your post by rewording the following questions to fit your scenario:

1) How many calories have been burned after 1 typical session of activity?

2)How much activity does it take to burn all the calories eaten in one day?

Complete the excel document to its full extent and label all of the charts completely. Graphs should be constructed this way:

• Graphs
  • Independent = X axis (18 pt. font , black font)
  • Dependent = Y axis (18 pt. font , black font)
  • Legend (16 pt. , black)
  • Numerical values for X and Y (14 pt., black font)
  • Bar graph should be in black with black border and white with black border (do under Format Data Series)
    • Gap width = 50%

1. Consider the function f(x1, x2) = (x1 + x2) . At the point x = (1, 0), we consider thesearch direction p⊤ = (−1, 1). Show that p is a descent direction and find all minimizers of the problem minα>0 f(xk + αpk).
