Converting Measurements

Converting Measurements Project 
Have you ever taken a trip to another country, or have you ever dreamed of doing so? There are a lot of beautiful places in the world, and each one is unique and special.
One of the ways certain countries may be different than others is in their standard units of measure. For example, in the United States, the most common way to measure a long distance is in miles, but in many other countries, it’s kilometers.
In this project, you’ll be measuring some items around your home and converting their measurements from one system to another.
For each section, please choose a different item. You will need to measure the item yourself for the first measurement, then show the equation and calculation you did to arrive at the second measurement.
ITEM 1: an item that you can pick up by yourself (i.e. book, pillow, TV remote, etc)
Item you chose: __________
Length in inches: _____________________
Length in centimeters (show work for full credit): ___________________________
ITEM 2: an item that you can pick up by yourself (i.e. book, pillow, TV remote, etc)
Item you chose: _____________________
Weight in pounds: ____________________
Weight in kilograms (show work for full credit): __________________________
ITEM 3: an item you can’t pick up by yourself (i.e. table, couch, bedframe, etc)
Item you chose: _____________________
Length in feet: ____________________
Length in meters (show work for full credit): ___________________________
ITEM 4: A liquid container (i.e. glass or bowl from your kitchen) – fill the item with water or another liquid 
Item you chose: ______________________
Volume in cups: ____________________
Volume in milliliters (show work for full credit): __________________________
Paragraph question
When we think about other parts of the world and the different ways they do things, sometimes we can tend to think that our way is the best way. Write a paragraph (at least three sentences) about what the Bible teaches us about how God created everyone equally and how every person from every culture, regardless of what measurements they use or what food they eat or what language they speak, is cherished and loved by God.

“Exploring Linear Relationships in Real Estate: A Regression Analysis”

Overview Recall that samples are used to generate a statistic, which businesses use to estimate the population parameter. You have learned how to take samples from populations and use them to produce statistics. For two quantitative variables, businesses can use scatterplots and the correlation coefficient to explore a potential linear relationship. Furthermore, they can quantify the relationship in a regression equation. Prompt This assignment picks up where the Module Two assignment left off and will use components of that assignment as a foundation. You have submitted your initial analysis to the sales team at D.M. Pan Real Estate Company. You will continue your analysis of the provided Real Estate Data Spreadsheet spreadsheet using your selected region to complete your analysis. You may refer back to the initial report you developed in the Module Two Assignment Template to continue the work. This document and the National Summary Statistics and Graphs Real Estate Data PDF spreadsheet will support your work on the assignment. Note: In the report you prepare for the sales team, the dependent, or response, variable (y) should be the listing price and the independent, or predictor, variable (x) should be the square feet. Using the Module Three Assignment Template Word Document, specifically address the following: Regression Equation: Provide the regression equation for the line of best fit using the scatterplot from the Module Two assignment. Determine r: Determine r and what it means. (What is the relationship between the variables?) Determine the strength of the correlation (weak, moderate, or strong). Discuss how you determine the direction of the association between the two variables. Is there a positive or negative association? What do you see as the direction of the correlation? Examine the Slope and Intercepts: Examine the slope and intercept . Draw conclusions from the slope and intercept in the context of this problem. Does the intercept make sense based on your observation of the line of best fit? Determine the value of the land only. Note: You can assume, when the square footage of the house is zero, that the price is the value of just the land. This happens when x=0, which is the y-intercept. Does this value make sense in context? Determine the R-squared Coefficient: Determine the R-squared value. Discuss what R-squared means in the context of this analysis. Conclusions: Reflect on the Relationship: Reflect on the relationship between square feet and sales price by answering the following questions: Is the square footage for homes in your selected region different than for homes overall in the United States? For every 100 square feet, how much does the price go up (i.e., can you use slope to help identify price changes)? What square footage range would the graph be best used for?

Title: Exploring Inverse Variation and Other Types of Variation in Real Life Situations

The variable is in the bottom of a fraction or in the denominator.  (The Opposite of Direct Variation)  In an inverse variation, the values of the two variables change in an opposite manner – as one value increases, the other decreases. For example, a biker traveling at 8 mph can cover 8 miles in 1 hour. If the biker’s speed decreases to 4 mph, it will take the biker 2 hours (an increase of one hour), to cover the same distance.
Please start by addressing one or more of the following topics to get the discussion going:
How would you describe the difference between direct variation and joint variation in words? Use examples to help illustrate.
Pick a field of study of interest to you and give an example of variation in that field. Some possible areas to consider are: Economics, Finance, Geometry and Physics. Example: If your hourly pay rate is $15/hour, then your weekly pay p is given by the formula p=15h where h is the number of hours worked in a week. So, your weekly pay varies directly as the number of hours worked in a week with the constant of variation = 15.
Most formulas are actually examples of variation. Pick a well-known formula and describe the type of variation as well as the constant of variation, k. Example: The area A of a triangle with base b and height h is given by the formula A=½bh. So, the area of a triangle varies jointly as the base and height (both direct) with the constant of variation = ½.
Share a favorite recipe; a) Triple the recipe; b) Take 1/2 of the tripled recipe.
Give an example from real life where composite functions are utilized. For ideas, you may look it up on the internet or find examples in the book.
