This scatter plot shows the foot circumference and height of 15 elephants.

Question

Now, let’s see what the model predicts. We can substitute into our equation that represents the linear model to predict the height of an elephant with a 110 cm foot circumference. Start by substituting 110 cm for x.
y
=
2x
y
=
2·

Answer 1

To predict the height of an elephant with a foot circumference of 110 cm using the equation \( y = 2x \), you can substitute \( x \) with 110 cm:

\[ y = 2 \cdot 110 \]

Now perform the calculation:

\[ y = 220 \]

Therefore, the prediction for the height of an elephant with a foot circumference of 110 cm is 220 cm.
