Cabs use a valuable commodity—gas! Research average gas prices from 2005–
2015 for the city you chose.
a. Create a table showing the average gas price each year.
b. Create a scatter plot of the data in your table.
c. What equation models the data? What are the domain and range of
the equation? Explain how you determined your answers.
d. Is there a trend in the data? Does there seem to be a positive correlation, a
negative correlation, or neither?
How much do you expect gas to cost in 2020? Explain.
Without knowing the specific city that was chosen, I am unable to provide the exact average gas prices from 2005-2015 for that city. However, you can easily research this information online by using government databases or by looking at historical gas price data.
a. To create a table showing the average gas price each year, you would list the years from 2005 to 2015 in one column and the corresponding average gas prices for each year in the next column.
b. To create a scatter plot of the data, you would plot the years on the x-axis and the average gas prices on the y-axis. Each data point represents a specific year and its corresponding average gas price.
c. The equation that models the data depends on the specific trend that the scatter plot exhibits. By looking at the scatter plot and analyzing the data, you may be able to identify a pattern or trend that can be modeled by a mathematical equation. The domain of the equation would be the years from 2005 to the present, and the range would be the corresponding average gas prices.
d. By analyzing the scatter plot, you can determine if there is a trend in the data and if there is a positive correlation, a negative correlation, or neither. If the data points on the scatter plot generally tend to increase as the years go by, there would be a positive correlation. If the data points tend to decrease as the years go by, there would be a negative correlation. If there is no clear pattern or trend, then there would be neither.
Predicting the exact gas prices in 2020 would depend on various factors such as global oil prices, inflation, and government policies. It is difficult to accurately predict gas prices several years into the future. However, you can analyze the trend in the scatter plot and make an estimate based on that trend. If the scatter plot shows a steady increase in gas prices over the years, you can reasonably expect gas to cost more in 2020 compared to previous years. Conversely, if the scatter plot shows a decrease or no clear trend, it would be difficult to estimate the gas prices in 2020.
