Usando conceptos de funciones lineales, se encuentra que hizo 5 cortes.

----------------

Una funcion lineale tiene el seguiente formato:

y(x) = ax + b

En que:

  • a eres lá inclinacion, o sea, lo que es pago por cada corte.
  • b eres el intercepto, o sea, lo pagamiento fixo por día.

----------------

  • Pagan $50 por corte realizado, o sea, a = 50.
  • $25 fixo al día, o sea, b = 25

Entonces, la funcion de su recibimiento y, como funcion de su numero de cortes x, es da por:

y(x) = 25 + 50x

----------------

  • Recibió $275, o sea, y(x) = 275

Entonces, el numero de cortes es:

y(x) = 25 + 50x

25 + 50x = 275

50x = 250

x = \frac{250}{50}

x = 5

Realizó 5 cortes.

Queremos encontrar y resolver una ecuación lineal que representa el problema dado.

Veremos que el miércoles Rocío realizó 5 cortes.

La información que se nos da es:

Rocío recive $50 por corte.

Adicionalmente, recibe $25 por día (esto se paga una sola vez)

Entonces si Rocío realiza x cortes, la cantidad de dinero que recibirá es:

C(x) = $25 + $50*x

Ahora sabemos que un dado día ella recibe $275, queremos ver cuantos cortes realizo ese día, entonces debemos resolver la ecuación lineal:

C(x) = $275 = $25 + $50*x

         $275 - $25 = $50*x

         $250 = $50*x

         $250/$50 = x = 5

Así podemos concluir que Rocío realizó 5 cortes.

Solve the inequality: <br> 8 = 5a &gt; -12<br> help!!! No links and correct awnser gets brainliest✨
VladimirAG [237]

Answer:

a = 4

Step-by-step explanation:

8 = 5a > - 12

8 + 12 = 5a > - 12 + 12

20 = 5a

20 ÷ 5 = 5a ÷ 5

a = 4

Check:

8 = 5(4) < 12

8 = 20 < 12

It is correct.

The ages of the 32 recruits in police academy are normally distributed with a mean of 27 with a standard deviation of 2. What is
aksik [14]
Since it's a sample size, we use x, as the mean and s= standard deviation
            _
Given:  x =27, s = 2 and total sample = 32.
Probability that a recruit is at least 31 years old?

Let's calculate the Z score :
              _
         X - x              31 - 27
Z = ----------- → Z = -------- → Z = 2 (now look up in the Z score table,
           s                      2


Area (Z=2) =0.9772 , but Z ≥ 2  (at least) , then :
Area (Z≥2) = Area (Z≤ - 2)  = 0.0228

P(≥31)= 0.0228

rusak2 [61]

Answer:

the graph is attached below

Step-by-step explanation:

y=x^2 - 2

LEts make a table to get the coordinates

we need to select integers between -3 and 3

x                  y=x^2 - 2

-2                y=(-2)^2-2=2               (-2,2)

0                 y= (0)^2 - 2= -2          (0,-2)

2                 y=(2)^2-2 = 2              (2,2)

Now we use the table for graphing the given equation

The graph is attached below
