Answer:
The hiker's elevation after 145 minutes will be 1958 meters.
Step-by-step explanation:
The equation of the trend line of the scatter plot showing a hiker's elevation is y = 8.77x + 686 .......... (1), where x is in minutes (say) and y is in meters (say).
Now, we have to predict the hiker's elevation after 145 minutes.
So, from equation (1) we get, y = 8.77 × 145 + 686 = 1957.65 ≈ 1958 meters. (Answer)
