Does Table 2 represent a linear function? If so, finda linear equation that models the data.
A real estate agent has developed a linear model for the price of a house, P, in dollars in terms of the area, A, in square feet for the homes in a certain neighborhood. The data set had areas ranging from 1,000 square feet to 4,500 square feet. Would predicting the prices of a home that is 4,900 square feet be interpolation or extrapolation? Explain. Using the model to predict the price of a 4,900 square foot home is extrapolation because 4,900 square feet is outside the range of the areas in the data. Using the model to predict the price of a 4,900 square foot home is interpolation because 4,900 square feet is inside the range of the areas in the data.

The bar graph reinforces the fact that one-person households are growing more common. It shows one-person households as a percentage of the U.S. total for five selected years from 1980 through 2012. a. Shown to the right of the bar graph is a scatter plot with a line passing through two of the data points. Use the two points whose coordinates are shown by the voice balloons to write the point-slope form of an equation that models one-person households as a percentage of the U.S. total, y, x years after 1980. b. Write the equation from part (a) in slope-intercept form. Use function notation. c. If trends shown by the data continue, use the model from part (b) to project one-person households as a percentage of the U.S. total in 2020.

Which like has a negative slope?
A FiveThirtyEight.com article reports that “Horror movies get nowhere near as much draw at the box office as the big-time summer blockbusters or action/adventure movies ... but there’s a huge incentive for studios to continue pushing them out. The return-on-investment potential for horror movies is absurd.” To investigate how the return-on-investment compares between genres and how this relationship has changed over time, an introductory statistics student fit a model predicting the ratio of gross revenue of movies from genre and release year for 1,070 movies released between 2000 and 2018. Using the plots given below, determine if this regression model is appropriate for these data
Can that regression be used to estimate the effect of the national unemployment rate on an individual’s earnings? Explain.
A scatter plot would be useful for: Showing the relationship between the sales of blank CDs and blank DVDs Showing the trend of sales, over time, of five different brands of blank DVDs Showing the relative number of sales of four different brands of blank DVDs Showing the top selling brands of blank DVDs
What is the estimated slope?
