## Description

Use completing the square to write f(x)=x^2+3x-18 in vertex form. What is the vertex for the function and how can you confirm the vertex

## Explanation & Answer

**f(x)=x ^{2}+3x-18 **

**=x ^{2}+2*x*3/2+9/4 -18-9/4**

**= (x+3/2) ^{2}-81/4**

**(y+81/4) = (x+3/2)) ^{2}**

y'= x'^2

Vertex (-3/2, -81/4)

STA 3215 UMTC Analyze of Patients Age Presentation

You are currently working at NCLEX Memorial Hospital in the Infectious Diseases Unit. Over the past few days, you have noticed an increase in patients admitted with a particular infectious disease. You believe that the ages of these patients play a critical role in the method used to treat the patients. You decide to speak to your manager, and together you work to use statistical analysis to look more closely at the ages of these patients.You do some research and put together a spreadsheet of the data that contains the following informationClient numberInfection disease statusAge of the patientYou are to put together a PowerPoint presentation that explains the analysis of your findings which you will submit to your manager. The presentation should contain all components of your findings. For review, the components of the report should include:Brief overview of the scenario and variables in the data setDiscussion, calculation, and interpretation of the mean, median, mode, range, standard deviation, and varianceDiscussion, construction, and interpretation of the 95% confidence intervalExplanation of the full hypothesis testConclusionThe calculations should be performed in your spreadsheet that you will also submit to your manager. You can find additional information on what to add to your PowerPoint presentation in this Word document. Use the questions in the worksheet as your guide for the contents of your presentation.For your final deliverable, submit your PowerPoint presentation and the Excel workbook showing your work.
