Question

1. the table above shows the elevation of 6 cities in california. what is the average elevation of these 6 cities?

city	elevation (m)
los altos	48
bombay beach	-69
westmorland	-48
imperial	-18
holtville	-3

Explanation:

Step1: Sum the elevations

First, we add up all the elevation values: \(24 + 48 + (-69) + (-48) + (-18) + (-3)\). Let's calculate step by step: \(24 + 48 = 72\); \(72 + (-69)=3\); \(3 + (-48)= -45\); \(-45 + (-18)= -63\); \(-63 + (-3)= -66\).

Step2: Calculate the average

The average is the sum divided by the number of cities (which is 6). So, we do \(\frac{-66}{6}\).

Answer:

\(-11\)
