Answer:
-3
Step-by-step explanation:
The product (the result of a multiplication) of 4 and a number. Let x be the unknown number:
4 · x = 4x
Plus 17:
4x + 17
Is 5:
4x + 17 = 5
Solve:
4x = 5 - 17
4x = -12
x = -12 ÷ 4
x = -3
8 times. 8 times 4 equals 32
Answer: 0.03567
Step-by-step explanation:
The probability mass function for Poisson distribution:-
, where = mean of the distribution.
Given : The number of cars that pass through a busy intersection has a Poisson distribution with rate λ=200 cars per hour.
Since 1 hour = 60 minutes.
then , The number of cars that pass through a busy intersection in minute =
Let x be the number of cars pass in one minute.
Then, the probability that no cars pass in a one minute time interval will be :
Hence, the probability that no cars pass in a one minute time interval is about 0.03567.
