13. En un pueblo, 5 personas escucharon una noticia. En una hora, cada una de ellas
Leona [12618]

Answer:

En un lapso de 5 horas, la noticia habrá llegado a toda la comunidad.

Step-by-step explanation:

Iniciamos con 5 individuos que conocieron la noticia.

Transcurrida una hora, cada uno de ellos comunicó la noticia a 5 más.

Las nuevas 5 personas luego se la contaron a otras 5, continuando este ciclo.

Cada persona escucha y narra la noticia solo una vez y la población del pueblo es un poco superior a 19000.

La fórmula que utilizamos para resolver este problema es la siguiente:

Empezamos con 5 personas que supieron de la noticia en el tiempo 'hora 0'.

Después de una hora, cada uno transmitió la noticia a 5 personas adicionales, lo que significa que después de la primera hora tendremos:

5+5^{2}=30 (I)

Esto incluye las 5 originales de la 'hora 0' más 25 que se enteraron en la primera hora. La fórmula que formulamos es esta:

5^{1}+5^{2}+5^{3}+...+5^{x}>19000 (II)

Debemos hallar el valor de x que cumpla con la ecuación (II).

Al calcular y sumar, descubrimos que:

5^{1}+5^{2}+5^{3}+5^{4}+5^{5}+5^{6}>19000

19530>19000

El valor de x que satisface (II) es x=6.

Para determinar el número de horas, observamos que en (I) el mayor exponente del 5 es 2. Por ese exponente, ha pasado una hora.

Así que para nuestro x=6, las horas transcurridas son 5 horas (una menos que el valor de x).

El pueblo entero conocerá la noticia a las 5 horas.

Jasmine bought 1.3 pounds of ham and 0.8 pounds of cheese from the deli and paid $11.28. She went back the following week and bo
lawyer [12517]
Let

x
represent the cost per pound of ham
y represent the cost per pound of cheese

<span>1.3x + 0.8y = 11.28....(1)
1.5x + 1.2y = 14.76....(2)

Now, let's multiply equation (1) by -1.2
...and multiply equation (2) by 0.8

Then we obtain -1.56x - 0.96y = -13.536.....(3)
</span>...and 1.2x + 0.96y = 11.808.....(4)


Adding (3) and (4) results in

-0.36x = -1.728............> x = 4.8

Substituting x back into (1)

1.3(4.8) + 0.8y = 11.28

y = 6.3

Cost per pound of ham = x = 4.8
Cost per pound of cheese = y = 6.3

An electronic product contains 40 integrated circuits. The probability that any integrated circuit is defective is 0.01, and the
Zina [12379]

Answer:

The chance that there is one or more defective integrated circuits is 33.10%.

Detailed solution:

Each integrated circuit can be either defective or not, which provides only two possible outcomes. As a result, this scenario is well-suited to be analyzed using the binomial probability distribution.

About the binomial distribution

This distribution calculates the likelihood of exactly x successes in n repeated trials where each trial has two possible results.

P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}

Here, C_{n,x} represents the count of combinations of x items selected from n elements, described by the formula:

C_{n,x} = \frac{n!}{x!(n-x)!}

And \pi is the probability of the event X occurring.

Applying it to the problem

The product contains 40 integrated circuits, so n = 40.

The probability that an individual integrated circuit is defective is 0.01, so \pi = 0.01.

Finding the probability of at least one defective circuit

There are two cases: either at least one integrated circuit is defective (probability P(X > 0)) or none are defective (probability P(X = 0)). Since probabilities sum to 1, we want to determine P(X>0).

P(X > 0) + P(X = 0) = 1

P(X > 0) = 1 - P(X = 0)

P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}

P(X = 0) = C_{40,0}.(0.01)^{0}.(0.99)^{40} = 0.6690

P(X > 0) = 1 - P(X = 0) = 1 - 0.6690 = 0.3310

Hence, the probability of having one or more defective integrated circuits is 33.10%.
