Using the Poisson distribution, the probabilities are given as follows:
- Less than 6: 0.3837 = 38.37%.
- Exactly 6: 0.1586 = 15.86%.
<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.
For this problem, the mean is given by:
The probability that exactly 6 tickets are written on a randomly selected day from this population is P(X = 6), hence:
[tex]P(X = 6) = \frac{e^{-6.4}(6.4)^{6}}{(6)!} = 0.1586/tex]
For less than 6, the probability is given by:
P(X < 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)
Using the same formula to find each value and adding them, we have that:
P(X < 6) = 0.3837.

Answer:
1. isosceles trapezoid- a trapezoid that has two congruent sides (other than the bases)
2. triangle- a polygon with three sides
3. line symmetry- property where a figure can be folded along a line to create two congruent mirror images
4. line of symmetry- the line which divides a figure into two congruent mirror images
5. rotational symmetry- property where a figure can be rotated less than 360° and still look the same
6. trapezoid- a quadrilateral with one pair of parallel sides
1/4 + 1/3 + 1/6 + 1/8 + 1/8
Must have same denominators
6/24 + 8/24 + 4/24 + 3/24(2)
Answer: 1
Answer:
A. {16}
Step-by-step explanation:
1/4 = x^-1/2
We have the exponent rule a^-1 = 1/a^1
Applying the rule, we get
1/4 = 1/x^1/2
x^1/2 = √x
1/4 = 1/√x
Now let's cross multiplying, we get
√x = 4
Taking square on both sides, we get
x = 16
The answer: A. {16}
Hope this will helpful.
Thank you.
