Answer:

There is no solution to this system.

Step-by-step explanation:

To solve this problem solve the second equation for y.

2x + y = 9

y = -2x + 9

Now that we have the value of y, we can put that in for y in the first equation and solve for x.

3y = -6x + 4

3(-2x + 9) = -6x + 4

-6x + 27 = -6x + 4

27 = 4

Because this is a false statement, we know that this system has no solution.

aleksandrvk [35]

Answer :E) Not enough information is given to determine the probability.

Step-by-step explanation:

Le A denotes the event that households in the United States own dogs .

and B denotes the event that households in the United States own cats.

As per given , we have

P(A)=36.5%= 0.365

P(B)=30.4% = 0.304

To find the probability that the selected household will own a dog or a cat, we apply the following formula :

P(A or B)=P(A)+P(B)+P(A and B)

But P(A and B) is not given to us.

i..e the probability that a house hold own both a cat and adg is not given to us.

Therefore, The correct option is (E) Not enough information is given to determine the probability.
