Burka [1]

Answer:

The values from least to greatest would be 202, 245, 245, 254, 276

The mean would be 244.4

The median would be 245

The mode would be 245

Step-by-step explanation:

To find the mean, you add all the numbers together and divide that sum by the number of numbers. In this case, you add all the numbers together and you get 1222. Next, you divide that by 5 because there are 5 numbers. To find the median, you order the numbers from least to greatest and find the middle number. For this question, the answer would be 245. Lastly, to find the mode you look for the number that appears the most. In this case it's 245.

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}
