Answer:

9 + 5.5x

Step-by-step explanation:

Since this is only asking for the perimeter, all we have to do is add the values.

0.3x + 24 + 5x + 0.2x - 15 = Perimeter of triangle.

=> 9 + 5.5x = Perimeter of triangle

Since this can't be simplified, 9 + 5.5x is the perimeter.

The number of lightning strikes in a year at the top of a particular mountain has a poisson distribution with a mean of 3.8. fin
atroni [7]

Let X be the number of lightning strikes in a year at the top of particular mountain.

X follows Poisson distribution with mean μ = 3.8

We have to find here the probability that in randomly selected year the number of lightning strikes is 0

The Poisson probability is given by,

P(X=k) = \frac{e^{-mean} mean^{x}}{x!}

Here we have X=0, mean =3.8

Hence probability that X=0 is given by

P(X=0) = \frac{e^{-3.8} 3.8^{0}}{0!}

P(X=0) = \frac{0.02237 * 1}{1}

P(X=0) = 0.0224

The probability that in a randomly selected year, the number of lightning strikes is 0 is 0.0224
