La probabilidad de que un caballo viva 20 años es 2/3 y la de que una vaca viva 20 años es 3/5, ¿cuál es la probabilidad de que tanto el caballo, como la vaca vivan 20 años?.
Por definición de probabilidad, la probabilidad de que tanto el caballo, como la vaca vivan 20 años es [tex]\frac{2}{5}[/tex].
En primer lugar, debes saber que 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.
En este caso, se llama suceso A al evento de que un caballo viva 20 años, mientras que el suceso B será el evento de que una vaca viva 20 años.
La intersección de sucesos es una operación cuyo resultado está compuesto por los sucesos no repetidos y comunes de dos o más conjuntos.
Esto es, la intersección de sucesos {A∩B} es el suceso formado por todos los elementos que son, a la vez, de {A} y {B}. De esta manera, el suceso {A∩B} se verifica cuando ocurren simultáneamente {A} y {B}.
Entonces, se debe calcular la probabilidad de que ocurra A y B al mismo tiempo, considerando que la probabilidad de la intersección de sucesos independientes (la probabilidad de cada uno de ellos no está influida porque el otro suceso ocurra o no, es decir, cuando ambos sucesos no están relacionados):
P(A∩B)= P(A)×P(B)
En este caso, la probabilidad de que ocurra A es [tex]\frac{2}{3}[/tex] y la probabilidad de que ocurra B es [tex]\frac{3}{5}[/tex]. Entonces:
P(A∩B)= [tex]\frac{2}{3}[/tex]×[tex]\frac{3}{5}[/tex]
P(A∩B)=[tex]\frac{2}{5}[/tex]
Finalmente, la probabilidad de que tanto el caballo, como la vaca vivan 20 años es [tex]\frac{2}{5}[/tex].

You have a 20 year annuity with a present value of $575,000. If the apr is 6%, what is the monthly yield?.
Annuities allow us to measure the cost of making payments over a period of time. Given the entries in the question given, the monthly yield will be;
$4119.48Since the interest will be compounded monthly, the number of periods will be 12. To determine the monthly payment from a payout annuity, use the formula;
Present value = Monthly yield (1 - (1 + APR/12)^-12 × n
APR/12
Fixing the above into the equation;
$575,000 = PMT (1 - (1 + 0.06/12)^-12 × 20
0.06/12
$575,000 = PMT 139.6
Making PMT the subject of the formula,
PMT = 575,000/139.6
PMT = $4118.911

Which of the following distinguishes prophase 1 of meiosis from prophase of mitosis?.
Based on a scientific study, the difference between prophase 1 of meiosis from prophase of mitosis is "homologous chromosomes pair up."
prophase 1 of meiosis vs. prophase of mitosisProphase 1 of meiosis is the first stage of meiosis which involves recombination and alleles crossing over genetic material to form non-identical haploid chromatids.
In Contrast, the prophase of mitosis is also the first stage of mitosis which splits the duplicated genetic fabric present in the nucleus of a parent cell to form new identical daughter cells.
However, one of the significant differences between prophase 1 of meiosis and prophase of mitosis in appearance is " homologous chromosomes pair up."
Hence, in this case, it is concluded that the correct answer is "homologous chromosomes pair up."

The comparative financial statements of marshall inc. Are as follows. The market price of marshall common stock was $82. 60 on december 31, 20y2.
It should be noted that the working capital will be $1584000, the current ratio is 2.80 while the quick ratio is 2.20.
From the complete information, the working capital is calculated thus:
= Current asset - Current liabilities
= 2464000 - 880000
= 1584000
The current ratio will be:
= Total current asset / Total current liabilities
= 2464000 / 880000
= 2.80
The quick ratio will be calculated thus:
Total current asset = 2464000
Less: Inventory = 420000
Less: Prepaid expenses = 108000.
Total quick assets = 1936000
Total current liabilities = 8800000

Explanation:
A spherical balloon is inflating with helium at a rate of. How fast is the balloon's radius increasing at the instant the radius is ft? how fast is the surface area increasing?.
Using implicit differentiation, and considering that the inflation rate is of 200 cubic feet per minute and the radius is of 5 feet, it is found that:
The radius is increasing at a rate of 0.6366 feet per minute.The surface area is changing at a rate of 80 feet squared per minute.The volume of an sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
Applying implicit differentiation, the rate of change is given by:
[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]
For this problem:
Inflation rate of 200 cubic feet per minute, hence [tex]\frac{dV}{dt} = 200[/tex]Radius is of 5 feet, hence [tex]r = 5[/tex]Then:
[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]
[tex]200 = 4\pi (5)^2\frac{dr}{dt}[/tex]
[tex]\frac{dr}{dt} = \frac{200}{100\pi}[/tex]
[tex]\frac{dr}{dt} = 0.6366[/tex]
The radius is increasing at a rate of 0.6366 feet per minute.
The surface area is:
[tex]S = 4\pi r^2[/tex]
Hence, the rate of change is:
[tex]\frac{dS}{dt} = 8\pi r\frac{dr}{dt}[/tex]
Hence:
[tex]\frac{dS}{dt} = 8\pi (5)(0.6366) = 80[/tex]
The surface area is changing at a rate of 80 feet squared per minute.
