Answer:
Subtracting 
from 
results in a polynomial. After subtracting 
from this polynomial the difference is 14
Step-by-step explanation:
The question given is:
Subtracting from results in a polynomial. After subtracting from this polynomial the difference is?
First we will Subtracting from
So, the polynomial we get is: 
Now, subtracting 
The difference is 14
So, Subtracting from results in a polynomial. After subtracting from this polynomial the difference is 14
The answer is uhmm let me see 2 4 6 8 10 12 14 16 18 20. Oh the answer is 4
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.
X + y = 40.....multiply by -4
4x + 6y = 180
-------------------
-4x - 4y = -160 (result of multiplying by -4)
4x + 6y = 180
------------------add
2y = 20
y = 20/2
y = 10 <===
x = 30
