Ajar contains 12 red balls, 7 green balls, 10 white balls, and 7 yellow balls.

USPshnik [31]

Answer:

C. Independent, 49/1296

Step-by-step explanation:

A jar contains 12 red balls, 7 green balls, 10 white balls, and 7 yellow balls.

Total balls = 12+7+10+7

Total balls= 36

Two balls are chosen at random with replacement.

The probability that the both balls are green = probability of the first ball to he green * probability of the second ball to be green

The probability that the both balls are green= 7/36 * 7/36

The probability that the both balls are green= 49/1296

5. 3/4 x 5 = 3.75 or $3\frac{3}{4}$

6. (2 x 7) - (2 x 5) = 4

7. The area is $\frac{6}{7}$

8. 70 - (20-13) would probably work

An animal shelter has 49 dogs and 28 cats . Last week There are 20 cats in the shelter, how many dogs are there ?

blsea [12.9K]

According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.

<u>Explanation:</u>

Let the number of dogs be d and the number of cats be c

If the ratio of dogs to cats is 49:28, then the ratio of d : c would be

$\frac{d}{c} = \frac{49}{28}$

On reducing the fraction, we get

$\frac{d}{c} = \frac{7}{4}$

It is shown that the number of cats is reduced to 20.

So, let the number of dogs after sometime be x

Thus,

$\frac{d}{c} = \frac{7}{4} = \frac{x}{20}$

After cross multiplying we get:

140 = 4x

x = 35

According to the ratio of dogs to cats, if there are 20 cats, there will be 35 dogs.
