Answer:
Air pressure = 
Step-by-step explanation:
Relationship between air pressure and altitude can be modeled by,
P = 14.7e
Where P = Air pressure
and h = altitude above the sea level
Air pressure on Mount Everest having altitude = 29028 feet abve the sea level will be,
P = 
= 
= 4.603
≈ 4.6 
Therefore, air pressure on Mount Everest = 4.6
1. 3 + 6 + 9 = 18
18/3 = 6 --> The average is 6
2. 15 + 5 + 8 + 4 = 32
32/4 = 8 --> The average is 8
3. 6 + 10 + 5 = 21
21/3 = 7 --> The average is 7
4. 14 + 9 + 7 = 30
30/3 = 10 --> The average is 10
Well then multiply 400 x 142 and get your answer of 56,800
