Answer:

$7

Step-by-step explanation:

Let the price of a box of popcorn = b and the price of a program = p

we can make 2 equations:

5b+3p = 41 and 3b+2p=26

We can use the subtraction method be able to eliminate one of the variables and isolate the other one - to do it I will equalize the 'b' in both equations by multiplying by 5 and 3 respectively

5(3b+2p=26)

-3(5b+3p = 41)

15b+10p=130

-(15b+9p=123)

p=7 (therefore the answer is 7$)

Why 7/10?

Well, the probability of pulling out a blue marble + pulling out a green marble is also written as [tex]\frac{2}{10} +\frac{5}{10}=\frac{7}{10}[/tex]

Answer: x<-9

Step-by-step explanation:

-2x>18

-2x/(-2)<18/(-2)

x< -9

The value of the solution in the inequality is,

⇒ x < - 9

A relation by which we can compare two or more mathematical expression is called an inequality.

We have to given that;

The inequality is,

⇒ - 2x > 18

Now, We can simplify as;

⇒ - 2x > 18

⇒ - x > 18/2

⇒ - x > 9

⇒ x < - 9

Thus, The value of the solution in the inequality is,

⇒ x < - 9

Answer:Bueno, normalmente en los artículos semanales intento transmitir dudas o cuestiones que están en el campo, los trending topics del sector porcino, y está claro que la estadística no es uno de ellos, pero precisamente ayer se dio una situación que me llevó a escribir ésta entrada.

Todos los que trabajamos en el sector porcino estamos acostumbrados a manejar y calcular un montón de datos que nos proporciona el programa de gestión, y en muchas ocasiones realizamos pequeñas (o grandes) pruebas, donde manejamos infinidad de números (pesos, GMD, IC etc…)

Lo que sí es cierto, es que la mayoría de nosotros usamos siempre la media como herramienta fundamental. Media de Nacidos vivos, Media de destetados, Media de peso al nacer, media de peso al destete…..media, media, media…y ¿qué tal si usáramos la Mediana?

Éste fue el debate que tuve ayer con un ingeniero agrónomo (si, si, y yo Veterinaria, diversión asegurada), y el que me ha inspirados para hoy.

Para el que, en estos momentos, esté rebuscando en los archivos de su cerebro, “yo esto lo sabía”, un pequeño recordatorio:

La media o promedio, Se interpreta como “punto de equilibrio” o “centro de masas  del conjunto de datos. Es un cálculo muy sencillo en el que intervienen todos los datos. Consiste en el sumatorio de todos los datos dividido por el número de valoresLa mediana, en cambio, es un valor de la variable que deja por debajo de sí a la mitad de los datos, y por encima, la otra mitad.( una vez que estos están ordenados de menor a mayor). Se sitúa, por lo tanto, en la mitad real de los datos.

Es mucho más difícil de calcular:

Con un ejemplo se entiende muchísimo mejor.

Imaginaos una empresa en la que la mayoría de los trabajadores tienen un sueldo de 1000 euros, excepto 2 encargados que cobran 2000 y el jefe que cobra 6000 euros mensuales.

¿Cuál es el salario medio de la empresa?

Si vemos la media sale casi 2000 euros, si miramos la mediana, nos da 1000.

¿Cuál se aproxima más a la realidad?

Cuando los datos son muy homogéneos la media nos da un valor representativo de la realidad, pero cuando los datos son muy heterogéneos no.

Un ejemplo más cercano a nosotros

Queremos saber el peso de los lechones a destete. Imaginemos que la camada A tiene los siguientes pesos:  (4-3-5-4.5-6.1-5-3-5.1-6.4-6-6.5-5.5-4.9).

He is incorrect

Step-by-step explanation:

Given

[tex]Price\ off = 10\%[/tex]

Required

Is the total savings, 30%

From the question, we understand that the price of is 10%.

Since there is no other deduction to the original price of the fridge, then the 10% represents the total savings.

Hence: 30% savings is incorrect.

Answer:

448.25(2dp)

Step-by-step explanation:

1. Find the are of the entire rectangle:

length x breadth = 38 x 28 = 1064mm^2

2. Find the area of one semicircle

([tex]\pi[/tex]r^2) divided by 2 =( [tex]\pi[/tex] x 14^2)divided by 2  = 98 [tex]\pi[/tex] = 307.8760801... = 307.88 mm^2

3. Multiply the area by 2

307.88 x 2 = 615.75 mm^2.     [ The sum of areas of 2 semicicles]

4. Subtract the area of the 2 semicircles from the area rectangle

1064-615.75 = 448.25 (2dp)

Answer:

Step-by-step explanation:

Multiply both sides by 5(k - 2)

-8*5(k - 2) ≤2               Combine -8 and 5

-40 (k - 2) ≤2                Remove the brackets

-40k + 80 ≤2               Subtract 80 from both sides

-40k ≤ -78                    Here's the trick part. Pay attention. Divide by - 40

k ≥ - 78 /- 40

k ≥ 1.95

Did you see what happened? The ≤ operation turned into ≥ That always happens when dividing by a minus or multiplying by a minus or if you change the side where literal coefficient is.

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{2}{3}[/tex] , then

y = [tex]\frac{2}{3}[/tex] x + c ← is the partial equation

To find c substitute (3, - 4) into the partial equation

- 4 = 2 + c ⇒ c = - 4 - 2 = - 6

y = [tex]\frac{2}{3}[/tex] x - 6 ← in slope- intercept form

Multiply through by 3 to clear the fraction

3y = 2x - 18 ( subtract 2x from both sides )

- 2x + 3y = - 18 ( multiply through by - 1 )

2x - 3y = 18 ← in standard form → D
