### Cell Phone Service Expenditure Over TimeThe following table represents the expenditure on cell phone services, in billions of dollars, measured $ t $ years after the year 2000.| $ t $ (Years after 2000) | Amount (Billions of Dollars) ||---------------------------|-----------------------------|| 5 | 113.42 || 6 | 126.55 || 7 | 138.13 || 8 | 142.48 |#### A: Determining the Regression LineTo find the equation of the regression line, follow these steps:1. **Define your variables:** - $ t $: Number of years after 2000 - Amount: The spending on cell phone services in billions of dollars2. **Write the equation:** The equation should be in the form $ y = mx + b $, where $ y $ is the amount, $ m $ is the slope, and $ b $ is the y-intercept. Round the final answer to two decimal places.#### B: Forecasting Future ExpenditureUsing the regression equation:- Estimate the time it will take for the expenditure on cell phone services to reach 216.7 billion dollars.- Write the equation used for this calculation.- Solve algebraically, showing all steps, and avoid using guesswork.- Round your final answer to two decimal places.

The following table shows the amount, in billions of dollars, spent on cell phone service t years a 2000. t Amount 5 113.42 6 126.55 7 138.13 8 142.48 A: Find the equation of the regression line. Define your variables and write the units. Round answer to 2 decimal places. B: Based on the regression equation, how long will it take for the amount spent on cell phone service to be 216.7 billion dollars? Write the equation you are using to solve the problem. Solve algebraically and show your work. Do not use guess and check. Round answer to 2 decimal places.

Use the data below for the PHONES questions that follow. Data compiled from the CIA World Factbook, https://www.cia.gov/. The number of cell phones in use in a country can be approximated from the number of main lines in use in that country by using the regression equation yhat=25+3x which had an R² of about 90%. (The numbers here are millions. For example, "1.2" would represent 1.2 million or 1,200,000.) PHONES 1 At the time the data was collected, the USA had about 314 million cell phones in use and about 150 million main lines in use. What was the residual for the USA? Enter a number of millions. For example, if your answer is 2.85 million enter "2.85". Do not enter anything else such as symbols or words.
