Can someone help me with this

Thepotemich [5.8K]

Answer:

D: 1/35

Step-by-step explanation:

First, you have to know how many marbles there are, and if you count them all up there are 15 marbles in total. Next, there are 3 blue marbles, so you would put the fraction as 3/15, or simplified to 1/5. Now, if you don't replace that blue marble, you now only have 14 marbles, and there are 2 yellow, which means you have a 2/14 chance of drawing a yellow marble, simplified to 1/7. But because there are two parts of the problem you are going to multiply 1/5 by 1/7 to get 1/35, which is your answer.

DochEvi [55]

Answer:

we predict 2,587 persons will adopt dogs

Step-by-step explanation:

out of 40 persons 23 adopt dogs

Then

out of 40×25 persons 23×25 adopt dogs

Then

out of 1000 persons 575 adopt dogs

Then

out of 1000×4.5persons 575×4.5 adopt dogs

Then

out of 4,500 persons 2,587.5 adopt dogs

Method 2 :

Let x Ben the number of persons we predict they will adopt dogs:

Here we have a proportional relationship:

Then

$\frac{4500}{40} =\frac{x}{23}$

$\Longleftrightarrow x = \frac{4500\times 23}{40} =2587.5$
