Question

: In a TV filming studio there is Planning the programs to record next month. They commonly record artistic and commercial programs. In On average, an artistic space requires 8 hours of recording, It costs $18,000 and produces an income of $38,000. While a commercial requires 1.6 hours of recording, It costs $8,000 and produces an income of $14,000. The studio management works 10 hours a day and for the Next month you have 26 working days. There is a commitment to record at least 10 spaces artistic. It is also established that the total time spent to commercial does not exceed 40%. Determine: to. Pose the mathematical model. Analyze the reason for these restrictions or limitations. b. Solve the problem using the Simplex method and interpret it.

a. Planteamiento del modelo matemático:

Definamos las siguientes variables:
- x: número de espacios artísticos a grabar
- y: número de comerciales a grabar

El objetivo es maximizar el ingreso total, que está compuesto por los ingresos de los espacios artísticos y los comerciales. Por lo tanto, la función objetivo será:

Maximizar: 38000x + 14000y

Sin embargo, tenemos las siguientes restricciones:
1. Se deben grabar al menos 10 espacios artísticos:
x ≥ 10
2. El tiempo total dedicado a comerciales no puede exceder el 40%:
1.6y ≤ 0.4(10)(8) = 32

Además, debemos tomar en cuenta las restricciones de tiempo disponibles:
- Cada espacio artístico requiere 8 horas de grabación, por lo que el tiempo total utilizado para grabar los espacios artísticos será de 8x horas.
- Cada comercial requiere 1.6 horas de grabación, por lo que el tiempo total utilizado para grabar los comerciales será de 1.6y horas.

La gerencia trabaja 10 horas diarias y hay 26 días laborables, por lo que el tiempo máximo disponible para grabar es de 260 horas (10 horas/día * 26 días).

Por lo tanto, también tenemos las siguientes restricciones de tiempo:
- Tiempo total utilizado para grabar los espacios artísticos: 8x ≤ 260
- Tiempo total utilizado para grabar los comerciales: 1.6y ≤ 260

b. Resolución del problema usando el método Simplex.

Para resolver este problema utilizando el método Simplex, necesitamos convertir las restricciones en igualdades. Agregamos variables de holgura y de exceso para convertir las desigualdades en igualdades.

Las restricciones convertidas son:

x - s1 = 10 (Restricción 1)
1.6y ≤ 32 (Restricción 2)
8x + s2 = 260 (Restricción 3)
1.6y + s3 = 260 (Restricción 4)

La tabla Simplex correspondiente sería:

| | x | y | s1 | s2 | s3 | RHS |
|-----|----|----|----|-----|-----|-------|
| s1 | 1 | 0 | 1 | 0 | 0 | 10 |
| s2 | 0 | 1 | 0 | 8 | 0 | 260 |
| s3 | 0 | 1.6| 0 | 0 | 1 | 260 |
| Z | -38| -14| 0 | 0 | 0 | 0 |

Aplicando el método Simplex, obtenemos que la solución óptima es:
x = 10
y = 20
Ingreso total = 38000(10) + 14000(20) = $780,000

With the aim of identifying the presence of the feline leukemia virus (FeLV), blood samples were collected from cats sent to a private veterinary clinic in the city of Belo Horizonte. Among the animals treated, it was possible to observe that age followed a Normal distribution with a mean of 4.44 years and a standard deviation of 1.09 years. Considering this information, determine the value of the third quartile of the ages of the animals treated at this veterinary clinic. ATTENTION: Provide the answer to exactly FOUR decimal places
A box of numbered pens has 12 red, 12 blue, 12 green and 12 yellow pens. The pens for each colour are numbered from 1 to 12. There is a unique number on each pen, so no pen is exactly the same as any other pen in the box. When reaching into the box to randomly draw five pens without replacement, what is the proportion of getting exactly four pens of the same colour (Note: the numbers matter but the order does not)?
