d) Use historical data to estimate.

Answer 1

To calculate when smartphone manufacturers shipped 500 million smartphones, one could use the exponential growth formula, plot a graph, apply a linear regression model, or use historical data to estimate.

Step-by-step explanation:

To calculate when smartphone manufacturers shipped 500 million smartphones, you could use several methods. One approach would be to use the exponential growth formula, especially if you know that the shipments are increasing at a constant percentage rate over time. Another method is to plot a graph of smartphone shipments over time and visually determine when the shipment levels reached 500 million. A third option is to apply a linear regression model if the shipment trends appear to be linear over time. This statistical method can predict future values based on past data trends. Lastly, you can use historical data to estimate when shipments reached the 500 million mark by extrapolating from past growth if a pattern is recognizable.
