A bead store buys beads at wholesale prices to sell them at a 75% markup. If a strand of beads costs the store $9.14, what is the selling price for a strand of beads

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:

K should be 5

Step-by-step explanation:

1/2 is .5 which leaves k/2 you need 2.5 to make three and 2.5*2 is 5 5/2 is 2.5 plus 5 is 3 therfore k is 5

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

Answer:

25,974 possible ID combinations

Step-by-step explanation:

Since the ID card will consist of one letter and three digits to find the total number of possibilities we simply multiply the number of letter options that exist by the total amount of numbers each letter can be followed by. There are a total of 26 letters in the English Alphabet. Since each letter is followed by only 3 digits, then the largest number that can exist after the letter is 999. Therefore, we simply multiply 26 by 999 to find the total number of possible outcomes.

26 * 999 = 25,974 possible ID combinations

The number of different such ID numbers are there should be 25,974 possible ID combinations

Since the ID card comprise one letter. Also, there are total of 26 letters in the English Alphabet.

So here we can do that we simply multiply 26 by 999 that comes 25,974.

Therefore, The number of different such ID numbers are there should be 25,974 possible ID combinations

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:

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
