Which statement is in-correct
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.

Prove the following,in a semigroup:
By induction, we can conclude that in a semigroup, all products of x1, x2, ...... xn (in that order) are equal.
What is semigroup?A semigroup is a mathematical structure consisting of a set of elements along with an associative binary operation. The operation must be associative, meaning that the result of the operation is independent of the order of the operands.
We can prove this by induction. Let S be a semigroup and x1, x2, x3, ..., xn be the elements of S.
Base Case: When n = 2, then the product of x1 and x2 is x1x2.
Inductive Step: Assume that the product of x1, x2, ..., xn (in that order) is equal. Then we can prove that the product of x1, x2, ..., xn+1 (in that order) is also equal.
Let a be the product of x1, x2, ..., xn (in that order). Then a = x1x2x3....xn.
Now the product of x1, x2, ..., xn+1 (in that order) is a x xn+1. Since S is a semigroup, a x xn+1 = x1x2x3....xn x xn+1.
Since the product of x1, x2, ..., xn (in that order) is equal, a = x1x2x3....xn. Therefore, the product of x1, x2, ..., xn+1 (in that order) is also equal.
By induction, we can conclude that in a semigroup, all products of x1, x2, ...... xn (in that order) are equal.

Below is the relative-frequency table of the probability distribution for the discrete random variable X, with X = "the number of cars owned by families in New York."
x P(X = x)
0 0.03
1 0.31
2 0.43
3 0.14
4 0.09
If the expected value is 1.95, what is the standard deviation?
0.93
0.99
0.96
Answer: To calculate the standard deviation of a discrete random variable, we need to know the expected value and the variance. The variance of a discrete random variable X is given by:
Var(X) = Σ [ (x - E(X))^2 * P(X = x) ]
where the summation is taken over all possible values of X, and E(X) is the expected value of X.
We are given that the expected value of X is 1.95. Using the formula for the variance and the probabilities given in the table, we can calculate the variance as follows:
Var(X) = (0 - 1.95)^2 * 0.03 + (1 - 1.95)^2 * 0.31 + (2 - 1.95)^2 * 0.43 + (3 - 1.95)^2 * 0.14 + (4 - 1.95)^2 * 0.09
Var(X) = 1.1429
To find the standard deviation, we take the square root of the variance:
SD(X) = sqrt(Var(X))
SD(X) = sqrt(1.1429)
SD(X) ≈ 1.07
Therefore, the standard deviation of the number of cars owned by families in New York is approximately 1.07. None of the options given match this value exactly, but 0.99 is the closest.

Tina used 10 1/2 yards of yarn to make three yarn dolls. She used 3 1/2 yards of yarn for the first doll and 4 1/8yards for the second doll. How much yarn did Tina use for the third doll?
Answer:
To find how much yarn Tina used for the third doll, we can subtract the total amount of yarn used for the first two dolls from the total amount of yarn used.
Total amount of yarn used = 10 1/2 yards
Amount used for first doll = 3 1/2 yards
Amount used for second doll = 4 1/8 yards
To add 3 1/2 and 4 1/8, we need to find a common denominator:
3 1/2 = 7/2
4 1/8 = 33/8
Common denominator = 8
So, 3 1/2 = 28/8 and 4 1/8 = 33/8
Total amount used for first two dolls = 28/8 + 33/8 = 61/8
Subtracting the total amount used for the first two dolls from the total amount of yarn used:
10 1/2 - 61/8 = 84/8 - 61/8 = 23/8
Therefore, Tina used 23/8 yards of yarn for the third doll.
Cuantos minutos tardará en llenarse un depósito de 10.080 litros de capacidad si recibe agua por 3 grifos diferentes que arrojan 60 litros, 70 litros, 80 litros cada minuto?
Answer:
El tanque tardará aproximadamente 48 minutos en llenarse.
Step-by-step explanation:
Podemos encontrar la tasa de llenado del depósito sumando las tasas de flujo de los tres grifos:
Tasa de llenado = 60 + 70 + 80 = 210 litros/minuto
Luego, podemos usar la fórmula:
Tiempo = Volumen / Tasa de llenado
Donde el volumen es 10.080 litros y la tasa de llenado es 210 litros/minuto. Sustituyendo estos valores, obtenemos:
Tiempo = 10.080 / 210 ≈ 48 minutos
Por lo tanto, tardará alrededor de 48 minutos en llenarse el depósito de capacidad 10.080 litros si recibe agua por tres grifos diferentes que arrojan 60 litros, 70 litros, 80 litros cada minuto.

. Your roommate, Sarah, offered to buy groceries for
you and your other roommate. The total bill was
$82. She forgot to save the individual receipts but
remembered that your groceries were $0.05 cheaper
than half of her groceries, and that your other
roommate’s groceries were $2.10 more than your
groceries. How much was each of your share of the
groceries?
According to the given information, your share of the groceries was $39.95, your other roommate's share was $42.05, and Sarah's share was $0.
What is equation?
An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equals sign (=). The expressions on both sides of the equation can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.
Let's call the amount of money Sarah spent on groceries "S".
Let's call the amount of money you spent on groceries "Y".
Let's call the amount of money your other roommate spent on groceries "O".
We know that:
S + Y + O = 82 (the total bill was $82)
Y = (S/2) - 0.05 (your groceries were $0.05 cheaper than half of Sarah's groceries)
O = Y + 2.10 (your other roommate's groceries were $2.10 more than your groceries)
We can use the second equation to substitute Y in the third equation:
O = Y + 2.10
O = (S/2) - 0.05 + 2.10
O = (S/2) + 2.05
We can now substitute both equations into the first equation:
S + Y + O = 82
S + ((S/2) - 0.05) + ((S/2) + 2.05) = 82
2S + 4 = 164
2S = 160
S = 80
Now that we know S, we can substitute it into the other equations to find Y and O:
Y = (S/2) - 0.05 = (80/2) - 0.05 = 39.95
O = Y + 2.10 = 39.95 + 2.10 = 42.05
So your share of the groceries was $39.95, your other roommate's share was $42.05, and Sarah's share was $80 - ($39.95 + $42.05) = $82 - $82 = $0.

Step-by-step explanation:
Hey there!
This question has given us information about both of the given variables, x, and y
It tells us the y is equal to x plus 8 and that x plus y is equal to 2
If y is equal to x plus 8, we can
substitute the y value into the second equation
This will give us the following equation:
x + (x + 8) = 2
Now we simplify to solve for x
2x + 8 = 2
2x = -6
x = -3
Now that we know the x value, we can substitute that value into any one of the two equations given to solve for y

Let y = x+8
[tex]\tt x+x+8=2[/tex]
[tex]\tt 2x+8=2[/tex]
Solve for x :-

a) 123°
b) 131°
c) 113°
d) 128°
e) 118°
Answer:
c) 113°
Step-by-step explanation:
Exterior angle is equal to the sum or the "remote" interior angles, that is the two angles that are not just next to the exterior angle. See image.
So the answer, quickly:
exterior angle
= 65° + 48°
= 113°
This is why:
(skip if you don't care)
The three angles in a triangle add up to 180° But also, a linear pair of angles also add up to 180°
So
x + 65° + 48° = 180°
x + y = 180°
y = 65° + 48°
