a twelve sided die with side labeled 1-12 will be rolled once. What is the probability of rolling a number less than 9?

puteri [66]

12 possible outcomes
any number less than 9 is 8 and below
8 sides of the dice are less than 9 out of 12 total sides
8/12 is the chance you’ll roll lower than 9

2/3 or 66% chance you’ll roll a number lower than 9

1. La suma de dos números es 115. El número mayor es dos veces más 22 unidades que el otro. Hallar

Lerok [7]

De acuerdo con un sistema de ecuaciones, tiene-se que los números son 31 y 84.

----------------

En el sistema de ecuaciones, tiene-se que los números son x e y.
Suma de 115, o sea, $x + y = 115$
El número mayor es dos veces más 22 unidades que el otro, o sea, $x = 2y + 22$

----------------

Primero se encuenta el número menor, reemplazando la segunda ecuación en la primera:

$x + y = 115$

$2y + 22 + y = 115$

$3y = 93$

$y = \frac{93}{3}$

$y = 31$

----------------

El número mayor es dado en función de el menor, o sea:

$x = 2y + 22 = 2(31) + 22 = 62 + 22 = 84$

Los números son 31 y 84.
