Answer:
j = 7
Step-by-step explanation:
First expand the right hand side:
3 = 3(j-6)
3 = 3j - 18
Then we can move 18 to the left hand side and calculate for j.
3 = 3j - 18
21 = 3j
j = 7

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.

Javed downloaded from the Internet two files that had a combined size of 696 megabytes. The size of the first file was 290 megabytes, and it took 5 minutes to download. Assuming that the files downloaded at a constant speed, how long did it take for the second file to download?
Answers
Answer:
7 minutes
Step-by-step explanation:
The computation of the time taken for downloading the second file is given below:
Given that
The combined size for both files is 696 megabyres
And, the size of the first file is 290 megabytes
So, the size of the second file is
= 696 - 290
= 406
Now for the first file it took 5 minutes to download
So for the second file, it would took
= 406 × 5 minutes ÷ 290
= 7 minutes

Write an equation in slope-intercept form of the line that passes through the given points.
Answers
Answer:
y = 1/2x+1
Step-by-step explanation:
Slope = Δy/Δx
The difference is y increases by 1 and difference in x increases by 2. So the slope is 1/2.
Slope-intercept form: y=mx+b
We take point (0,1) and input into this equation.
1= 1/2×0 +b
1 = b

An aquarium holds 11.95 cubic feet of water, and is 2.8 feet long and 1.4 feet wide. What is its depth? Round your answer to the nearest whole number.
Answers
Answer:
3.05feet
Step-by-step explanation:
Given data
Volume = 11.95 cubic feet
Lenght = 2.8 feet
Width= 1.4feet
Depth= ????
We know that the expression for the volume is
V= L*W*D
substitute
11.95= 2.8*1.4*D
11.95= 3.92D
divide both sides by 3.92
D= 11.95/3.92
D= 3.05
Hence the depth is 3.05feet approx
A daily newspaper sells monthly subscriptions for $15. Each individual copy of the newspaper costs $0.75. In a month that has exactly 30 days, how much could be saved by purchasing a subscription instead of purchasing an individual copy each day?
Answers
Answer:
With the subscription, $7.5 will be saved.
Step-by-step explanation:
Giving the following information:
A daily newspaper sells monthly subscriptions for $15. Each copy of the newspaper costs $0.75.
First, we need to calculate the total cost of buying 30 newspapers individually:
Total cost= 0.75*30
Total cost= $22.5
Difference= 22.5 - 15= $7.5
With the subscription, $7.5 will be saved.
How many solutions does this system of equations have?
y = -1/3x + 7
y = -2x^3 + 5x^2 + x - 2
Answers
Answer:
its one solution
Step-by-step explanation:
This system of equations have a unique solution.
What is a system of equation?A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.
For the given situation,
The system of equations are
y = -1/3x + 7 ------- (1)
y = -2x^3 + 5x^2 + x - 2 ------- (2)
Equation 1 is a linear equation and equation 2 is a polynomial equation.
So graph these two equations to find the solution.
The graph below shows the plotting of these two equations and
solution of these equations.
From the graph, it is clearly seen that this system of equation has only one solution.
Hence we can conclude that this system of equations have a unique solution.

Of 570 people, 365 were male and 368 had brown hair. Of those with brown hair, 108 were female. What is the probability that a person was male or had brown hair? Write your answer as a reduced fraction.
Answers
Answer:
473/570
Step-by-step explanation:
No. of male = 365
No. of female = 570-365 = 205
No. of male with brown hair = 260
No. of female with brown hair = 108
the probability that a person was male or had brown hair = 365/570+108/570 = 473/570 [ for or case we add probabilities]
Answer:
Around 83% 473/ 570
Step-by-step explanation:
365 males + 108 females with brown hair = 473
Divide the number of outcomes desired by the total number of outcomes 473/570 = 0.829824....... = 82.98.....%
