6x + 3y = 12\\
6x - 5y = 60\\\\
6x + 3y = 12\\
-6x + 5y = -60\\
--------\\
8y=-48\\
y=-6\\\\
6x+3\cdot(-6)=12\\
6x-18=12\\
6x=30\\
x=5

6x+3y=12. so... 6x=12-3y.

6x-5y=60, so... 6x=60+5y

As 6x=6x

12-3y=60+5y

12-60=8y

8y=-48

So y=-48/8=-6

When y=-6,

6x-5(-6)=60

6x+30=60

6x=30

Therefore x=5.

So x=5 and y=-6.

An experiment observes an integer uniformly chosen from {1.2, 3.4.5, 6, 7, 8, 9, 10, 11.12}
Brrunno [24]

Answer:

Options D & E are independent

Step-by-step explanation:

For any of the options to be independent, they have to be mutually exclusive i.e A ∩ B = 0

A) A ∩ B = {1, 2, 3}. They are not mutually exclusive and so they are not independent.

B) A ∩ B = {3}. They are not mutually exclusive and so they are not independent.

C) A ∩ B = {8}. They are not mutually exclusive and so they are not independent.

D) A ∩ B = 0. They are mutually exclusive and thus they are independent.

E) A ∩ B = 0. They are mutually exclusive and thus they are independent.
