This photograph, taken from a tethered balloon
five weeks after the great earthquake of April

city of San Francisco by the quake and subsequent
fire. The view is looking over Nob Hill toward
business district, South of the Slot, and the

Adding uncertainties

• We add variance NOT standard deviation

• Example
• V1 203
• V2 304
• DV ? 3 4 7
• DV sqrt(916) 5
