A meteorologist is monitoring the atmospheric pressure as his height above sea level varies. The meteorologist determines that t
Burka [1]

Answer:

The function p(n) is represented by p(n) = 103\cdot (0.88)^{n}.

Step-by-step explanation:

Statement indicates that atmospheric pressure decreases exponentially when height above sea level is increased. This fact is represented by the following model:

p(n) = p_{o}\cdot r^{n} (Eq. 1)

Where:

p_{o} - Atmospheric pressure at sea level, measured in kilopascals.

r -Atmospheric pressure decrease rate, dimensionless.

n - Height above sea level, measured in kilometers.

p(n) - Current pressure, measured in kilopascals.

If we know that p_{o} = 103\,kPa and r = 0.88, the function p(n) is represented by:

p(n) = 103\cdot (0.88)^{n}

If the probability of a chance event is 0.82, it is more likely to happen than which of the following probabilities of another c
Charra [1.4K]

Answer:

0.8

Step-by-step explanation:

Things to remember:

- You can add as many 0's on the end of a decimal and it will still equal the same number, as long as the 0's are on the right side of the decimal point. For example, 0.7 = 0.7000.

- The lowest value has the lowest probability

So, let's rewrite the options with the same amount of decimal points:

1.00

0.90

0.80

0.85

Now, find the value under 0.82. In this option, the lowest value is 0.80, and it is under 0.82, so it is the answer.
