Answer:

La probabilidad que hay de que sea fin de semana es \frac{2}{7}

Step-by-step explanation:

La Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso. En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles. Entonces, la probabilidad de un suceso cualquiera A se define como el cociente entre el número de casos favorables (número de casos en los que puede ocurrir o no el suceso A) y el número total de casos posibles. Esta se denomina Ley de Laplace.

P(A)=\frac{numero de casos favorables}{numero de casos posibles}

En este caso:

  • número de casos favorables: 2 (cantidad de días del fin de semana)
  • número de casos posibles: 7 (cantidad de días totales en la semana)

Reemplazando:

P(A)= \frac{2}{7}

<u><em>La probabilidad que hay de que sea fin de semana es </em></u>\frac{2}{7}<u><em></em></u>

Answer:

0.5158

Step-by-step explanation:

The exponential decay of a given material is used to describe the process by which a material decreases in size and amount over a specific period of time. The material will decay with respect to its decay factor. Therefore, if the 10-hour decay factor is approximately 0.2661, the 5-hour growth/decay factor will be: (0.2661)^(5/10) = (0.2661)^0.5 = 0.5158.

What is the graph of the function? <br><br> f(x) = 2x2
spayn [35]
Let's plug in a few points to see which graph belongs to the function f(x) = 2x^2

Let's say x =0, let's find y!
2(0)^2 = 2(0) = 0

So one point on our line is (0.0)

Just finding this point right here eliminates 3 of the answer choices. Your answer is the graph that goes through the point (0,0)

For your added convenience, I have attached the graph. :)
