18 min x 3 = 54 min

Answer:

95,040 ways

Step-by-step explanation:

The first position has 12 choices

The second has 11 choices (since first is filled)

The third has 10 choices

The fourth has 9 choices

The fifth has 8 choices

So the number of ways they can make the ranking will be;

12 * 11 * 10 * 9 * 8 = 95,040 ways

The number of ways could the voters (student body) rank their first 5 choices is 792 ways.

Since Last year at a certain high school, 12 students sought the nomination for president of the student body.

So, here

we use the combination here

[tex]= 12!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\times 7!\div 5!7!\\\\= 12\times 11\times 10\times 9\times 8\div 5\times 4\times 3\times 2[/tex]

= 792 ways

Therefore, The number of ways could the voters (student body) rank their first 5 choices is 792 ways.

Answer:

QS = 76

Step-by-step explanation:

Given R is the midpoint of QS, it means the distance from R to each endpoint is equal, that is:

QR = RS

We are given

QR = 2x + 16

RS = 5x - 17

Equating:

2x + 16 = 5x - 17

Subtracting 5x:

2x - 5x + 16 = -17

Simplifying:

-3x +16 = -17

Subtracting 16:

-3x = - 16 -17 = -33

Dividing by -3:

x = 11

Let's find

QR = 2x + 16 = 22 + 16 = 38

The length of QS is double this value: QS = 2*38 = 76

QS = 76

Answer:

La probabilidad es [tex]0.2508[/tex]

Step-by-step explanation:

Sabemos que según datos de una empresa aseguradora de vehículos, dos de cada cinco accidentes son provocados por conductores en estado de ebriedad. Entonces, si definimos el evento

[tex]A[/tex] : ''Accidente provocado por un conductor en estado de ebriedad''

La probabilidad de este evento es

[tex]P(A)=\frac{2}{5}[/tex]     (dato del problema)

Por lo tanto, en cada accidente que ocurre, la probabilidad de que ocurra el evento [tex]A[/tex] es  [tex]\frac{2}{5}[/tex] .

Ahora bien, si suponemos cada uno de estos accidentes independientes y con probabilidad de ocurrencia ''p'' constante a lo largo del tiempo, estamos ante la presencia de un proceso Bernoulli.

Dado un proceso de Bernoulli, definimos la variable aleatoria discreta ''[tex]X[/tex]'' como el número de éxitos del proceso Bernoulli para un número fijo de ensayos.

En este caso vamos a definir

[tex]X[/tex] : ''Número de accidentes provocados por conductores en estado de ebriedad de un total de n accidentes''

Se dice que [tex]X[/tex] tiene distribución binomial de parámetros ''n'' y ''p''.

Lo denotamos [tex]X[/tex] ~ Bi (n,p)

En nuestro ejercicio el valor de ''n'' es 9 (son los ensayos que fijamos) y el valor de ''p'' es [tex]\frac{2}{5}[/tex] (definimos como ''éxito'' que el accidente sea provocado por un conductor en estado de ebriedad).

Ahora bien para calcular probabilidad vamos a utilizar la siguiente fórmula :

[tex]P(X=x)=(nCx)p^{x}(1-p)^{(n-x)}[/tex]    (I)

'' [tex]P(X=x)[/tex] '' es la probabilidad de que la variable aleatoria [tex]X[/tex] asuma el valor x. En particular, buscamos [tex]P(X=3)[/tex] que es la probabilidad de que de nueve accidentes (fijados), tres sean provocados por conductores en estado de ebriedad.

'' [tex](nCx)[/tex] '' es el número combinatorio definido como

[tex]nCx=\frac{n!}{x!(n-x)!}[/tex]

Reemplazando los datos en la ecuación (I) :

[tex]P(X=3)=(9C3)(\frac{2}{5})^{3}(\frac{3}{5})^{6}=0.2508[/tex]

La probabilidad pedida es [tex]0.2508[/tex]

Answer:

x = 139

Step-by-step explanation:

Isosceles triangle.

Let the equal angles = y

y + y + 98 = 180   {Sum of all the angles of triangles}

  2y + 98 = 180

          2y = 180 - 98

          2y = 82

           y = 82/2

          y = 41

x = 41 + 98     { exterior angles equals the sum of interior opposite angles}

x = 139

Answer:

Hay 14 monedas de 5 centavos y 3 monedas de 10 centavos.

Step-by-step explanation:

Llamemos "c" a las monedas de 5 centavos y "d" a las monedas de 10 centavos.

Hay once  monedas más de 5¢ que las de 10¢. La expresión matemática para ello es:

c = d + 11    [1]

El total es 1 dolar. La expresión matemática para ello es:

0,05c + 0,10d = 1   [2]

Si reemplazamos [1] en [2],

0,05(d + 11) + 0,10d = 1

0,05d + 0,55 + 0,10d = 1

0,15d = 0,45

d = 3

Si reemplazamos d = 3 en 1,

c = d + 11 = 3 + 11 = 14

Answer:

the dot product is 13

Step-by-step explanation:

The computation of the dot product is shown below:

Given that

x =  (1, −2, 0, 4)

y = (1, 2, 3, 4)

Based on the above information

The dot product is

= (1) (1) + (-2) (2) + (0) (3) + (4) (4)

= 1 - 4 + 0 + 16

= 13

Hence, the dot product is 13

We simply multiplied each of them so that the correct value could come

Answer:

.0076

Step-by-step explanation:

Answer: y = 129, x = 51

Step-by-step explanation:

angles 129 and y are corresponding, so they are equal to each other

y and x are supplementary

so, y + x = 180

x = 180 - y = 180 - 129 = 51

Answer:

I belive y has to be at least 133 because it's just a little bit longer than the 229 one.

And x is most likely to be 125 because if you line up 129 with x, x is should be a little smaller so x should be 125

Answer:

The answer is

[tex] \huge y + 7 = - \frac{3}{4} (x - 16) \\ [/tex]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question we have the final answer as

[tex]y + 7 = - \frac{3}{4} (x - 16)[/tex]
