</h2>
Step-by-step explanation:
The total number of rolls in a box = 15
The number of defective items = 3
Two rolls are to be selected, one after the other. The probability of selecting a defective roll followed by another defective roll = ?
The probability that the first roll is detective = 
The probability that the second roll is detective = 
Required probability = 
= 
1 gal = 4 quarts

Answer:
Al estudiante le falta caminar
de kilómetro.
Step-by-step explanation:
Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio. Dos tercios equivale a la fracción
.
El estudiante avanza medio kilómetro en bus. Un medio equivale a la fracción
, por lo tanto un medio es la mitad de una cantidad. Para calcular la distancia recorrida en bus se realiza la siguiente multiplicación:

Resolviendo:

Entonces, la distancia recorrida en bus es
de kilómetro.
Para calcular la distancia recorrida a pie se calcula la diferencia entre la distancia total a recorrer por el estudiante y la distancia recorrida en bus. Esto es:

Resolviendo:

<u><em>Al estudiante le falta caminar </em></u>
<u><em> de kilómetro.</em></u>
Answer:
Answer A
Step-by-step explanation:
We see that ABC is similar to DEF. Pay attention to the order of these letters. The order that they read (left-to-right) is the order that they are similar. For example, AB is similar to DE. Despite being different triangles, they are both the <em>first two </em>letters in the triangle. So, knowing this, we can conclude that answer choice A is correct.
