Answer:
The answer in the attached figure
Step-by-step explanation:
Let
x------> the abscissa
y-----> the ordinate
we know that

The answer in the attached figure
L being the length, W being the width.
So:
if the Length is 8cm more than twice the width, we have:
2W+8
so it's:
perimeter of a rectange = 2(2W+8)+2W
You asked me not to simplify it, so that should be your answer.

Answer:
0.36427
Step-by-step explanation:
Mean = λ = 18 messages per hour
P(X = x) = (e^-λ)(λ⁻ˣ)/x!
P(X ≤ x) = Σ (e^-λ)(λ⁻ˣ)/x! (Summation From 0 to x)
But the probability required is that the messages thay come in an hour is between 15 and 20, that is, P(15 < X < 20)
P(15 < X < 20) = P(X < 20) - P(X ≤ 15)
These probabilities will be evaluated using a cumulative frequency calculator.
P(X < 20) = 0.65092
P(X ≤ 15) = poissoncdf(18, 15) = 0.28665
P(15 < X < 20) = P(X < 20) - P(X ≤ 15) = 0.65092 - 0.28665 = 0.36427.
