Si un triángulo tiene una hipotenusa de 15 cm y un cateto que mide 12 cm, ¿cual es la longitud del otro cateto?

BartSMP [9]

Answer:

9cm

Explicación:

El teorema de pitagoras nos dice que la hipotenusa al cuadrado es igual a la suma de los catetos al cuadrado:

$c^{2} =a^{2} + b^{2}$

Donde c es la hipotenusa y a y b son los catetos.

Por lo cual, podemos reemplazar c por 15cm y a por 12cm :

$15^{2} =12^{2} +b^{2}$

Finalmente , debemos resolver la ecuación para b, así que b es igual a :

$225=144+b^{2} \\225-144=144+b^{2} -144\\81=b^{2} \\\sqrt{81} =b\\9=b$

Por lo tanto, la longitud del otro cateto es 9 cm

Event A: Spinning violet or yellow on the spinner.

OlgaM077 [116]

Answer:

$\sf P(A \cap B)=\dfrac{1}{4}$

Step-by-step explanation:

$\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}$

Event A - spinning violet or yellow

Assuming that the spinner has 4 different colors (red, orange, violet and yellow) - see attachment.

$\implies \sf P(A) = \dfrac{2}{4}=\dfrac{1}{2}$

Event B - rolling an even number

Assuming the number cube has 6 sides numbered 1, 2, 3, 4, 5 and 6. Therefore, the even numbers are 2, 4 and 6.

$\implies \sf P(B)=\dfrac{3}{6}=\dfrac{1}{2}$

Events A and B are independent events as the outcome of one event does not affect the outcome of the other event.

For independent events A and B:

$\implies \sf P(A \cap B)=P(A)P(B)$

To find P(A and B), substitute the found values of P(A) and P(B):

$\implies \sf P(A \cap B)=\dfrac{1}{2} \times \dfrac{1}{2}=\dfrac{1}{4}$
