The statement "The Poisson distribution is always skewed right" is incorrect. Option A
What is Poisson distribution?The Poisson distribution is a discrete probability distribution that is used to model the probability of a given number of events occurring in a fixed interval of time or space, assuming that the events occur independently and at a constant rate.
The key features of the Poisson distribution include:
The distribution is discrete, meaning that it only takes on integer values.The distribution is defined by a single parameter, lambda (λ), which represents the expected number of events that will occur in the interval.The distribution is skewed right, with a long tail on the right-hand side.The mean and variance of the distribution are both equal to λ.The statement "The Poisson distribution is always skewed right" is incorrect.
The Poisson distribution can be skewed left, right, or approximately symmetric depending on the value of its parameter lambda. If lambda is small, the distribution will be skewed right. If lambda is large, the distribution will be approximately symmetric.

What is the outcome and sample space of getting a sum of 9 when three dice are rolled
Answers
The outcome of getting a sum of 9 when three dice are rolled is that the sum of the three numbers shown on the dice must add up to 9. The sample space for this scenario can be written as S = { (1,3,5), (2,3,4), (2,4,3), (3,2,4), (3,4,2), (4,2,3), (4,3,2), (5,1,3)}
What is outcome?Outcome refers to the result of an action or event. It is the end result of the process and can be positive, negative, or a mix of both. Outcome can also refer to the impact of an event, such as the effect it has on the environment, the people affected, or the economy.
The sample space for this scenario is the set of all possible combinations of three dice that add up to 9.
Each of the elements in this set represents a combination of numbers on the dice that will add up to 9 when rolled. For example, the first element of this set (1,3,5) means that if the three dice are rolled, the numbers shown on the dice will be 1, 3, and 5, and the sum of the numbers will be 9.
When determining the sample space for the outcome of rolling three dice, the order of the numbers does not matter. Therefore, the sets (2,3,4) and (4,2,3) are equivalent, since the sum of the numbers is still 9 regardless of the order.
In conclusion, the outcome of getting a sum of 9 when three dice are rolled is that the sum of the three numbers shown on the dice must add up to 9. The sample space for this scenario is the set of all possible combinations of three dice that add up to 9.

sk A pond in the shape of a right-angled triangle is shown below. Calculate the perimeter of the pond. Give your answer in metres to 1 d.p. 2.42 m.
Answers
The perimeter of the pond from the calculation is 5.42 meter
How to solve for the perimeter of the pondWe would first have to find the sides using the angle that we have here
b / 2.42 = sin 74

At the start of the month, the counter on the copy machine reads 6,583. At the end of the moth, it reads 82,110. The copies cost 1 1/3 cents a piece. What was the approximate total cost of the copies for this month?
Answers
Answer:
$1007.03
Step-by-step explanation:
You want the cost of copies for the month at 1 1/3 cents each if the copy counter ran from 6583 to 82110 during the month.
Number of copiesThe number of copies made is the difference in counter readings:
82110 -6583 = 75,527 . . . . . copies made
CostEach costs 1 1/3 = 4/3 cents, so the cost of these copies is ...
(75,527 copies) × (4/3 cents/copy) = 100702 2/3 cents ≈ 100703 cents
There are 100 cents in a dollar (or other currency unit), so the cost is about ...
(100703¢)/(100¢/$) = $1007.03
The total cost of copies for the month is about $1007.03.

After calculating the straight angle we know that ∠BAC is (A) 150°.
What is the straight angle?
A straight angle in geometry is one that is 180 degrees in length.
It looks like a straight line, which is why it is known as a straight angle.
In other words, it is an angle whose sides are in the same straight line but opposite to the vertex.
A straight angle in geometry is an angle with a vertex point that is at 180 degrees.
In other words, an angle becomes a straight angle when its arms point in the opposite direction.
So, we know that s straight angle is always 180°.
∠BAD is a straight angle.
We can also observe that:
∠BAD = ∠BAC + ∠CAD
Now, solve as follows:
∠BAD = ∠BAC + ∠CAD
180 = ∠BAC + 50
180 - 50 = ∠BAC
130° = ∠BAC
Therefore, after calculating the straight angle we know that ∠BAC is (A) 150°.

The order of the side lengths of the triangles from the least to the greatest is Lk < JL < IJ < JK < IK.
How does angle opposite to a side of triangle affect its size?
If the angle facing a side of a triangle increases, then the length of the opposite side may also increase. This is because the larger the angle, the more vertical the opposite side becomes, and therefore the longer it may become.
Conversely, if the angle facing a side of a triangle decreases, then the length of the opposite side may also decrease. This is because the smaller the angle, the less vertical the opposite side becomes, and therefore the shorter it may become.
From the given diagram, the largest side of the triangle will be the side directly opposite the largest angle.

50 hombres tienen provisiones para 20 días a razón de tres raciones diarias. Sí las
raciones se disminuyen en 1/3 y se aumentan 10 hombres ¿Cuántos días durarán
los víveres?
Answers
Answer:
Para resolver este problema, primero debemos encontrar la cantidad total de raciones que tienen los 50 hombres para 20 días a razón de tres raciones diarias:
50 hombres x 3 raciones por día x 20 días = 3000 raciones
Esto significa que tienen un total de 3000 raciones de alimentos para los 50 hombres durante 20 días.
Luego, podemos calcular la cantidad de raciones diarias después de la disminución en 1/3:
3 raciones diarias - (1/3)(3 raciones diarias) = 2 raciones diarias
Esto significa que cada hombre ahora recibe 2 raciones diarias en lugar de 3.
Después de aumentar el número de hombres en 10, tenemos un total de 60 hombres:
50 hombres + 10 hombres = 60 hombres
Podemos calcular la cantidad total de raciones diarias para los 60 hombres durante los días que durarán las provisiones:
60 hombres x 2 raciones por día = 120 raciones diarias
Finalmente, podemos calcular la cantidad de días que durarán los víveres:
3000 raciones totales / 120 raciones diarias = 25 días
Por lo tanto, los víveres durarán 25 días después de disminuir las raciones en 1/3 y aumentar el número de hombres en 10.
