Question

question 2 (multiple choice worth 6 points) (01.02h mc) the depth at which dolphins dive, y, in feet, as related to the duration of the dive, t, in seconds, is represented by the linear model y = 0.28 + 5.79t. if the dive duration is 3 seconds, what is the predicted depth of the dive? 0.48 feet -17.59 feet 17.59 feet -0.48 feet

Explanation:

Step1: Substitute t=3 into model

$\hat{y} = 0.23 + 5.78(3)$

Step2: Calculate the product term

$5.78(3) = 17.34$

Step3: Sum to find predicted depth

$\hat{y} = 0.23 + 17.34$

Answer:

17.59 feet
