Oh I like this one I think it’s letter B because inside is whole numbers and 0 isn’t a whole number, outside is negatives so it’s B hope it helps
Using the Poisson distribution, the probabilities are given as follows:
A. 0.0888 = 8.88%.
B. 0.1354 = 13.54%.
C. 0.8646 = 86.46%.
<h3>What is the Poisson distribution?</h3>
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
The parameters are:
- x is the number of successes
- e = 2.71828 is the Euler number
- is the mean in the given interval.
Item a:
10 hours, 2 calls per hour, hence the mean is given by:
.
The probability is P(X = 20), hence:
Item b:
1 hour, hence the mean is given by:
The probability is P(X = 0), hence:
Item c:
The probability is:

Answer:
No, that is not possible
Explanation:
P = 2L + 2W
Insert numbers into equation
p=(2)(20)+(2)(11)
Step 1: Simplify both sides of the equation.
p=(2)(20)+(2)(11)
p=40+22
p=(40+22)(Combine Like Terms)
p=62
p=62
The perimeter is 62, not 64, so the perimeter can't be 64 if the length 20 and the width is 11.
Answer:
26/3 or 8.67
Step-by-step explanation:
Arc lengths are congruent and the radii are the same implies angle at the centre is also equal,
Hence length of the chords are equal too
4x+2 = x+7
3x = 5
x = 5/3 or 1.67
Length of QR = 4x+2
= 4(5/3) +2
= 20/3 + 2
= 26/3 = 8.67
Try plugging in the 4 solutions and see if they fit
for example a, x - 6 is not extraneous because
left side = sqrt (-3*-6 - 2) == sqrt16 = 4 or -4
right side = -6 + 2 = -4
so x = -6 is not extraneous
