Answer:

A

The lengths of LV and OE are 15cm, and the lengths of LD and EV are 3√7 cm and 9/√7 cm, respectively.

Since LOVE is a kite, LV and OE are perpendicular bisectors of each other. Let the length of LD be x, and the length of EV be y. Then, we can use the Pythagorean theorem and the fact that the diagonals bisect each other to set up two equations:

x² + (LV/2)² = DV²/4

y² + (OE/2)² = LE²/4

Simplifying each equation and substituting the given values, we get:

x² + (LV/2)² = 81/4

y² + (OE/2)² = 225/4

We also know that the diagonals bisect each other, so we can set up another equation:

LV/2 + OE/2 = LO = VE

Substituting the given value for LE, we get:

LV/2 + OE/2 = 15

Solving this equation for one of the variables, we get:

LV = 30 - OE

Substituting this expression into the first equation above, we get:

x² + ((30 - OE)/2)² = 81/4

Simplifying and rearranging, we get:

OE² - 60OE + 675 = 0

Using the quadratic formula, we get:

OE = (60 ± √(3600 - 2700)) / 2

OE = 15 or 45

If OE = 15, then LV = 30 - 15 = 15, and we can solve for x and y:

x² + 7.5² = 81/4

y² + 7.5² = 225/4

Solving these equations, we get:

x = 3√7

y = 9/√7

If OE = 45, then LV = 30 - 45 = -15, which is impossible for a length. Therefore, the solution is:

LV = OE = 15

x = 3√7

y = 9/√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.

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).

Step-by-step explanatio

The value of b is 2.

To find the value of b, we need to equate the equations of the semi-circle and the parabola.

The equation of the semi-circle is given as fx = √(9 - x²).

The equation of the parabola is given as gx = b - (1/4)x².

Since both graphs represent the same function, we can equate them and solve for the value of x:

√(9 - x²) = b - (1/4)x²

To simplify the equation, let's square both sides:

9 - x² = (b - (1/4)x²)²

Expanding the right side of the equation:

9 - x² = b² - 2b(1/4)x² + (1/16)x⁴

Combining like terms:

9 - x² = b² - (1/2)bx² + (1/16)x⁴

Since the two sides of the equation are equal for all values of x, the coefficients of each power of x must be equal. Comparing the coefficients, we have:

-1 = -b/2          (coefficient of x² term)

0 = 1/16          (coefficient of x⁴ term)

From the coefficient of the x² term, we can solve for b:

-b/2 = -1

b/2 = 1

b = 2

\(t1 {15y08 \frac{18 \gamma \gamma }{?} }^{2} \)

Answer:

answer choice a! (16)

Step-by-step explanation:

Total area equals 900 + 315 + 150 = 1,365 square yards. Triangles 1 and 2 add up to 315 square yards.

Divide the land into two triangles and a rectangle, and then add the areas of each to determine the playground's size.

The rectangle's area is: since it is 50 yards long and 18 yards wide.

Area of a rectangle equals length times breadth times 50 divided by 18 equals 900 square yards.

With a base of 18 yards and a height of 35 yards, one of the triangles has the following area:

Triangle 1's area is equal to (18 35) / 2 (base x height), which equals 315 square yards.

The other triangle's area is: Since the top side of the second triangle is labeled as 50 yards, and its base is 20 yards, and its height is 50 - 35 = 15 yards.

Area of triangle 2 is (20 15) / 2 (base x height), which equals 150 square yards.

As a result, the playground's total area is:

Total area equals 900 + 315 + 150 = 1,365 square yards. Triangles 1 and 2 add up to 315 square yards.

The choice that comes the closest to the predicted playground space is 1,750 square yards. This choice, however, is not the right response. There are 1,365 square yards in the right answer.

The vertex is (9,5) an area = 85  in²

Hence option C is correct.

Given vertices of rectangular flag is

A(4, 5), B(4, −12) and C(9, −12)

Let the fourth vertex be D(x, y)

Since x coordinate of A and B are same

So length AB = 17

Since it is rectangle then

length CD = 17

Therefore y = 17 - 12 = 5

Since X coordinate of C is 9 theretofore x = 9

Thus vertex D be (9,5)

So length of rectangle = 17

The variable X has a binomial distribution in the following distributions:

A. When the medicine is tried with two patients, X is the number of patients for whom the medicine worked.

C. When the medicine is tried with six patients, X is the number of patients for whom the medicine worked.

In a binomial probability distribution, the number of "Successes" in a series of n experiments is represented as either success/yes/true/one (probability p) or failure/no/false/zero (probability q = 1 p), depending on the outcome's boolean value.

In a binomial distribution, we have a fixed number of independent trials (in this case, the number of patients), and each trial has only two possible outcomes (success or failure). The probability of success remains the same for each trial (in this case, the probability of the medicine working is 30%).

Option B does not represent a binomial distribution since it counts the number of patients for whom the medicine does not work, which is the complement of success. Option D is not a binomial distribution as it counts the number of doses each patient needs to take, which is not a success/failure outcome.

So, the correct answers are:

A. When the medicine is tried with two patients, X is the number of patients for whom the medicine worked.

C. When the medicine is tried with six patients, X is the number of patients for whom the medicine worked.

The largest value of x that satisfies the inequality is approximately -1.8639.

To find the largest possible value of x that satisfies the inequality 1/(x + 2)⁶ > 1,000,000, we can start by rearranging the inequality:

1/(x + 2)⁶ > 1,000,000

Taking the reciprocal of both sides:

(x + 2)⁶ < 1/1,000,000

Now, let's take the sixth root of both sides:

x + 2 < (1/1,000,000)\(}^{1/6\)

Calculating the right side:

x + 2 < 0.1361

Subtracting 2 from both sides:

x < 0.1361 - 2

x < -1.8639

Therefore, the largest value of x that satisfies the inequality is approximately -1.8639.

There are 8 different trips that can be made from City X to City Z, passing through City Y.

To find the number of different trips that can be made from City X to City Z, passing through City Y, we can use the multiplication principle of counting.

First, we need to choose one of the 2 major roads from City X to City Y. Then, for each of these roads, there are 4 major roads from City Y to City Z, and we need to choose one of these roads.

By the multiplication principle of counting, the total number of different trips from City X to City Z, passing through City Y, is the product of the number of choices at each stage. Thus, we get:

Number of different trips = Number of roads from City X to City Y x Number of roads from City Y to City Z

= 2 x 4
