Answer: 0.107
Step-by-step explanation:
En una caja tenemos 8 canicas.
5 son rojas
3 son verdes.
Se retira una canica, y no se remplaza.
Quiero calcular la probabilidad de sacar dos canicas verdes.
La probabilidad de sacar una canica verde en el primer intento, es igual al cociente entre el numero de canicas verdes y el numero total de canicas.
p1 = 3/8
Ahora, en el segundo intento, en la caja voy a tener 2 canicas verdes (por que ya saque una) y 7 canicas en total. Entonces la probabilidad va a ser:
p2 = 2/7.
Y la probabilidad conjunta (es decir, la probabilidad de sacar las dos canicas de color verde) va a ser igual al producto de las probabilidades individuales.
P = p1*p2 = (3/8)*(2/7) = 0.107
The equation that is an example of inverse variation is B none
<h3>How to determine the equations that are direct variation?</h3>
There are several types of variations.
Some of them include:
- Direct variation
- Joint variation
- Inverse variation
Equations that are inverse variation are represented as:
y = k/x
Where k represents the constant of proportionality or variation
From the list of options, none of the equations has the form y = k/x
Hence, the equation that is an example of inverse variation is B none

The answer is B. I’m doing this right now at the moment and i have an A in math class so. Good luck! :)
Answer:
$8.75
Step-by-step explanation:
Pete would pay 8.75 because if you divide 5/4 and 12.50/10, you find that each Coke costs 1.25. 1.25 times 7 is 8.75
