Need help what would the depth be after 30 minutes

Answer 1

Answer:

  108.7 ft

Step-by-step explanation:

Put 30 where x is and do the arithmetic.

  y = -3.29·30 -10 = -98.7 -10 = -108.7

The trend line predicts the depth to be 108.7 ft after 30 minutes.

Real-world considerations in scuba diving may cause the diver to level off or head toward the surface before 30 minutes elapse. The trend line does not model these effects.
