New data collected on roller coasters, comparing height of the initial drop to the speed of the coaster, found that the regression line equation is actually y = 0.502 + 12.250
Part A: What is the predicted speed for a drop of 100 feet?
Part B: What would be the predicted speed for a drop of 500 feet?
Part C: Do you think it is likely that a roller coaster will reach the speed found in Part B?

Part A: What is the predicted speed for a drop of 100 feet?: 62.45

Part B: What would be the predicted speed for a drop of 500 feet?:263.25

Part C: Do you think it is likely that a roller coaster will reach the speed found in Part B?:No, it is not likely, it is impossible for a roller coaster to travel at this speed

Step-by-step explanation:

I just did this question on algebra nation.
