Answer:
There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
What is the probability that exactly two such busses arrive within 3 minutes of each other
The mean is one bus each 10 minutes. So for 3 minutes, the mean is 3/10 = 0.3 buses. So we use
This probability is P(X = 2).
There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
Answer:
interchange the role of x and y
x=9y+5
x-5=9y
<u>x-5</u><u> </u>=y
9
so,f^-1(x)= <u>x-5</u>
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>9

Answer:
2
Step-by-step explanation:
Let f(x) = 2x – 1
Substitute (x + b) in place of x.
f(x + b) = 2(x + b) – 1
= 2x + 2x –1
To find :
