Answer:

La pregunta no está completa. Explicaré las propiedades de funcionamiento de los números racionales.

Explanation:

Las principales propiedades de los números racionales son:

- Propiedad de cierre

- Propiedad de conmutatividad

- Propiedad asociativa

- Propiedad distributiva

La propiedad de cierre establece que para dos números racionales cualesquiera xey, x + y, x-y, x * y, y x / y también será un número racional.

La propiedad de conmutatividad establece que para dos números racionales cualesquiera xey, x + y = x + y; x - y ≠ y - x; x * y = y * x; x / y ≠ y / x.

La propiedad asociativa establece que para cualesquiera tres números racionales dados x, y y z, (x + y) + zyx + (y + z) son iguales.

La propiedad distributiva establece que para tres números cualesquiera x, y y z, x × (y + z) = (x × y) + (x × z).

About 1313% of the population of a large country is hopelessly romantichopelessly romantic. If two people are randomly selecte

Answer:

Probability both are hopelessly romantic = 0.0169

Probability at least one is hopelessly romantic = 0.2431

Step-by-step explanation:

We are given that about 1313% of the population of a large country is hopelessly romantic.

Also, given two people are randomly selected.

Firstly, Let Probability that the population of a large country is hopelessly romantic = P(R) = 0.13

(a) Probability both are hopelessly romantic is given by = Probability that first person is hopelessly romantic $\times$ Probability that second person is hopelessly romantic

= $P(R) \times P(R)$

= 0.13 $\times$ 0.13 = 0.0169

(b) Now, Probability that the population of a large country is not hopelessly romantic = P(R') = 1 - P(R) = 1 - 0.13 = 0.87.

So, Probability at least one is hopelessly romantic is given by = 1 - Probability that none of them is hopelessly romantic

= $1 - (P(R') \times P(R'))$

= 1 - (0.87 $\times$ 0.87)

= 1 - 0.7569 = 0.2431

Function “p” is in the form y=ax^2 + C. If the values of “a” and “c” are both less than 0, which graph could represent “p”?

kati45 [8]

Answer:

Step-by-step explanation:

Since the value of a is less than 0, the graph of the parabola would be opening downwards. Because of this we can rule out option C. In a quadratic equation, c represents the y-intercept, and, in this case c is negative, meaning the y-intercept is less than 0. Only option B has a downward-opening curve and a y-intercept less than 0, so it is the answer.
