Question

This scatter plot shows the foot circumference and height of 15 elephants.
Try again to find the value of 2·115. You can think of this as 2 groups of 100 plus 2 groups of 15.

Answer 1

To calculate \( 2 \cdot 115 \), we can proceed with the given breakdown:

1. Calculate \( 2 \cdot 100 \):
\[
2 \cdot 100 = 200
\]

2. Calculate \( 2 \cdot 15 \):
\[
2 \cdot 15 = 30
\]

3. Add the two results together:
\[
2 \cdot 115 = 200 + 30 = 230
\]

So, \( y = 2 \cdot 115 = 230 \).
