Answer with Step-by-step explanation:
We are given that
P(A)=0.4 and P(B)=0.7
We know that

We know that
Maximum value of
=1 and minimum value of
=0






It is not possible that
is equal to 1.1


Multiply by (-1) on both sides

Again, 



Multiply by (-1) on both sides

Hence, 
Answer:
either of two angles whose sum is 180°.
Step-by-step explanation:
Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees
2^-2
Is 1/2^2=1/4
3 x 1/4 is 3/4
The answer is 3/4 I think
To find the x intercept set y = 0
x^2 + x - 2 =0
(x+2)(x-1) = 0
x = -2 , x = 1
Answer: a the first answer is right
