Air pressure decreases exponentially with increases in elevation. The air pressure, y, (in atm units) at a given elevation, I, (in meters) can be modeled using equation y = e-los, where k is the decay constant.
At an elevation of 5486 m where the air pressure is 0.5 atm, what is the value of k?
A k=
In( 5486)
0.5
O B. k=
In(0.5)
5486
Ock=-In ( 545
D. k=-In ( 59.56

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
