Answer:
0.0498 = 4.98%
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.
Inquiries arrive at a record message device according to a Poisson process of rate 15 inquiries per minute.
Each minute has 60 seconds.
So a rate of 1 inquire each 4 seconds.
The probability that it takes more than 12 seconds for the first inquiry to arrive is approximately
Mean of 1 inquire each 4 seconds, so for 12 seconds 
This probability is P(X = 0).


X directly varies with y which means as x increases, y also increases. In this case, we represent a constant of proportionality of k.
Applying laws of <span> proportionality,
x =k y
48 = k* 16
k = 3
when y is 5
x = k y
x = 3* 5
x = 15</span>
Answer:
Answer in simplified mixed form is 1 5/6
Step-by-step explanation:
We need to solve: -6 7/8 divided by (-3 3/4)
This can be written as:
-6 7/8 ÷ (-3 3/4)
Since -6 7/8 = -55/8 and -3 3/4 = - 15/4
So we can write :
-6 7/8 ÷ (-3 3/4) = -55/8 ÷ (-15/4)
or (-55/8 ) / (-15/4)
or (-55/8) * (-4/15)
or -(-220/120)
or 11/6
or 1 5/6 , this is the answer
We got the answer in simplified mixed form is 1 5/6
Answer:
The width is 9.5 ft
Step-by-step explanation:
Perimeter for a rectangle is given by
P = 2 (l+w)
43.8 = 2 (12.4+w)
Divide each side by 2
21.9 = 12.4+w
Subtract 12.4 from each side
21.9-12.4 = w
9.5 = w
The width is 9.5 ft
