Answer:
angular velocity = 12π Radians per second
Step-by-step explanation:
The angular velocity is a measure of the rotation/revolution speed of an object, relative to another point.
In order to present the answer in radians per second, let us first establish the relationship between radians and rotations/revolution.
one complete revolution = 360° = 2π Radians
∴ 1 roration = 2π Radians
12 rotations = 12 × 2π Radians = 24π Radians
Angular velocity in radians = 24π Radians in 2 seconds
Now let us convert to radians per seconds.
24π Radians = 2 seconds
2 seconds = 24π Radians
∴ 1 second = (24π Radians) ÷ 2
1 second = 12π Radians
∴ angular velocity = 12π Radians per second

Answer:
3x and x
Step-by-step explanation:
because you can put them together to make 2x+2
Answer:
3x and -x
Step-by-step explanation:
Like terms are terms that are in the same form. So essentially, 3x and -x are both able to be added and subtracted from each other in this case.

The required circumference of the given circle is 25.12 cm as shown figure.
What is the Circumference of a circle?The Circumference of a circle is defined as the product of the diameter of the circle and pi.
C = πd
where 'd' is the diameter of the circle
We have been given data as follows:
The radius of the circle (r) = 4 cm
Circumference of the circle = 2πr
Substitute the values in the above formula and we get
Circumference of the circle = 2π(4)
Circumference of the circle = 3.14(8) = 25.12 cm
The required circumference of the given circle is 25.12 cm.

Supongamos que el 20% de los objetos fabricados por una empresa son defectuosos. Escogemos 4 objetos al azar. Hallar la probabilidad de que (a) 2 sean defectuosos, (b) 3 sean defectuosos, (c) ninguno sea defectuoso.
Responder:
0,1536
0.0256
0.4096
Explicación paso a paso:
Dado que :
p = 0,2
Número de ensayos, n = 4
1 - p = 1 - 0,2 = 0,8
Probabilidad de que 2 sean defectuosos;
Usando la fórmula de distribución binomial:
P (x = 2)
P (x = x) = nCx * p ^ x * (1 - p) ^ (n - x)
P (x = 2) = 4C2 * 0.2 ^ 2 * 0.8 ^ 2
P (x = 2) = 6 * 0,04 * 0,64
P (x = 2) = 0,1536
3 están defectuosos:
P (x = 3) = 4C3 * 0,2 ^ 3 * 0,8 ^ 1
P (x = 3) = 4 * 0,008 * 0,8
P (x = 3) = 0,0256
Probabilidad de que ninguno sea defectuoso:
P (x = 0) = 4C0 * 0.2 ^ 0 * 0.8 ^ 4
P (x = 0) = 1 * 1 * 0,4096
P (x = 0) = 0,4096
Usando la distribución binomial, se encuentra que hay una probabilidad de:
a) 0.1536 = 15.35% que 2 sean defectuosos.
b) 0.0256 = 2.56% que 3 sean defectuosos.
c) 0.4096 = 40.96% que ninguno sea defectuosos.
Para cada objeto, solo hay dos resultados posibles. O está defectuoso o no lo es. La probabilidad de que un objeto sea defectuoso es independiente de cualquier otro ítem, lo que significa que se utiliza la distribución binomial para resolver esta cuestión.
Distribución binomial:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Los parámetros son:
n es el número de ensayos. p es la probabilidad de éxito en un ensayo x es el número de éxitosEn este problema:
4 objetos, por eso [tex]n = 4[/tex].20% son defectuosos, por eso [tex]p = 0.2[/tex].Item a:
Esta probabilidad es P(X = 2), o sea:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{4,2}.(0.2)^{2}.(0.8)^{2} = 0.1536[/tex]
Probabilidad de 0.1536 = 15.35% que 2 sean defectuosos.
Item b:
Esta probabilidad es P(X = 3), o sea:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{4,3}.(0.2)^{3}.(0.8)^{1} = 0.0256[/tex]
Probabilidad de 0.0256 = 2.56% que 3 sean defectuosos.
Item c:
Esta probabilidad es P(X = 0), o sea:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{4,0}.(0.2)^{0}.(0.8)^{4} = 0.4096[/tex]
Probabilidad de 0.4096 = 40.96% que ninguno sea defectuosos.

Mason used 1/6 of a liter of milk to make 1/8 of a jug of tea. How much milk in liters is required to fill the jug
Answer:
1.33 liters of milk are required to fill the jug.
Step-by-step explanation:
With the information provided, you can use a rule of three to find the amount of milk required to fill 1 jug of tea given that Mason used 1/6 of a liter of milk to make 1/8 of a jug of tea:
1/6 f a liter of milk → 1/8 of a jug of tea
x ← 1 jug of tea
x=(1/6*1)/1/8
x=(1/6)/(1/8)
x=(1*8)/(6*1)
x=8/6
x=4/3=1.33
According to this, the answer is that 1.33 liters of milk are required to fill the jug.

what is the domain of the function, f(x)?
Answer:
B. 3≤x≤ 6
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for all possible x-values. Look at the graph of the function- there are no points on the graph where x=1, so we know that C and D are definitely wrong since they include 1. The two that are left look very similar, but A means "3 is greater than or equal to x, x is greater than or equal to 6." This has to be wrong because it says that 3 is greater than 6, which is obviously incorrect. The only answer left is B, which is correct because it includes all possible x-values.
lmk if this is incorrect or hard to understand, hope this helps!!!

A group of friends wants to go to the amusement park. They have $201.75 to spend on parking and admission. Parking is $5.75, and tickets cost $24.50 per person, including tax. How many people can go to the amusement park?
Answer:
8 friends
Step-by-step explanation:
The group of friends will park only once, so you only need to add $5.75 once, but you still need to add the amount of money for all the people who are in the car, 24.50 x 8 is equal to exactly 196 dollars, so 196 + 5.75 is equal to exactly 201.75, which is the amount of money the group has, so 8 people can come.
Answer: The answer is 8 :)
