Answer:

A

Step-by-step explanation:

2,3y + 2 + 3,1y = 4,3y + 1,6 + 1,1y + 0,4

<=>2,3y - 4,3y + 3,1y - 1,1y = -2 + 1,6 + 0,4

<=> 0y = -2/5 ( nonsense )

A has no solution

Done!! :))

Regina has a bag of marbles that contains 3 blue marbles, 4 red marbles, and 5 yellow marbles. She draws one marble, then replac
iVinArrow [24]

Answer:  

Possible outcomes=12

P(\text{Blue marble first})=\frac{1}{4}

P(\text{Yellow marble})=\frac{5}{12}

P(\text{ Blue then yellow})=\frac{5}{48}

Step-by-step explanation:

We can see these two events are independent as Regina replaced marble after drawing one marble.

We can find possible outcomes by adding number of blue, red and yellow marbles.

\text{Possible outcomes}=3+4+5=12

Let us find probability of getting a blue marble on first draw.

P(\text{Blue marble})=\frac{3}{(3+4+5)} =\frac{3}{12} =\frac{1}{4}

Now we will find probability of getting yellow marble.

P(\text{Yellow marble})=\frac{5}{(3+4+5)} =\frac{5}{12}

We can find probability of getting a blue marble and then yellow marble by multiplying both probabilities.

P(\text{ Blue then yellow})=\frac{1}{4}* \frac{5}{12} =\frac{5}{48}

Therefore, probability of getting a blue marble and then yellow marble is \frac{5}{48}.

Help if anyone knows! Thanks

You have to find how many times 40 (the denominator) goes into 120 (attempts). That's 3, so you take the numerator (17) and multiply it by that same number. And 17 times 3 is 51.

Abdul is making a map of his neighborhood. He knows the following information:
Sladkaya [172]
I think the best answer from the choices listed above is the third option. The theorem that Abdul can use to determine the remaining distances for his map would be the Triangle Proportionality Theorem. It states that i<span>f a line parallel to one side of a </span>triangle<span> intersects the other two sides of the </span>triangle<span>, then the line divides these two sides proportionally.</span>
