Answer:
D
Step-by-step explanation:
3x=y+4
4y=3x-1
Subtract 4 from both sides of the second equation to isolate y:
y=3x-4
Therefore, the correct answer is D. Hope this helps!
Well... if she has 8 yards, and a yard equals to 18 inches. So.. I would divide 8 and 1/4. After you do the reciprocal, you would get 32 pieces.

Answer:
a. A and B are disjoint
Step-by-step explanation:
We know that P(A and B)=0, It means that event A and event B have nothing in common and it means that event A and event B are disjoints events.
The event A and event B are independent if
P( A and B)= P(A)*P(B)
P(A)*P(B)=0.3*0.2=0.06
So, P(A and B)≠P(A)*P(B)
Hence events A and B are not independent.
Option a is A and B are disjoints which is correct
Option b is A and B are neither disjoints nor independent which is partially false as A and B are disjoints event.
Option c states that A and B are independent which is clearly false.
Option d states that A and B are disjoints and independent which is partially false as A and B are not independent.
Hence the correct option is option A.
