The regression equation provided in the image is:

$DD = 2.69 + 0.0138D$

where:

• $DD$ is the duration of the dive in minutes.
• $D$ is the depth of the dive in meters.

We need to find the duration for a dive to a depth of 150 meters. Substituting $D = 150$ in the equation:

$DD = 2.69 + 0.0138 \times 150$

Let's calculate this value.The duration of a typical dive to a depth of 150 meters, according to the regression equation, is 4.76 minutes.
