Use the model I attached below to answer the questions. Thanks!
1. What is the slope ? Round to the nearest tenth (1 decimal place).
2. What is the intercept ? Round to the nearest integer.
3. The value -6 should be used in the model to predict the revenue of Walmart in what year?
4.What is the estimated revenue of Walmart in 2089? Round to the nearest billion US dollars.
5. In what year will the estimated revenue of Walmart be 1,268 billion US dollars? Note: I am asking for the year, not the number of years since 2000. This may happen between two years. Round to the nearest year.
6. Using the revenue data for Jesaki Inc. for the past few years, we apply linear regression to the data to find a model
y = 31.8 x-892,
where is Jesaki's annual revenue in billions of US dollars, and is the number of years since 2000. Use this model, together with the revenue model you found for Walmart to answer the question below.
When will Jesaki's revenue overtake Walmart?
Note: I am asking for the year, not the number of years since 2000. This may happen between two years. Round to the nearest year.
