From cm to m, you would need to divide 100 to get your conversion answer which is 4.78 m.
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.

Easy just subtract 20 and 12 and its 8 the reason how i got that is because the ladder is 20 feet high and it now stands 12 feet on the fence so the fence is only 8 feet PLZ MARK ME BRAINIEST MY ANSWER IS RIGHT i have done the test ur welcome.
Answer:
do 70x70=4,900 than do 100 x100=10,000 than add them to gether and you get 10,4900
