4 would be your answer lol
Answer:
Step-by-step explanation:
Given that According to a video streaming service, 48% of American couples are "cheaters", that is—they promise each other to watch a filmtogether, but one of them first watches it alone.
Here if this is binomial with two outcomes we can easily say that the other 52% couples go together movies.
But here there are not only two outcomes.
The other possibilities are:
i) Either both do not go to movies
ii) Both cheat and go to movies separately
Thus since there are not exactly two outcomes, we cannot say the other 52% go to movies together.
As much as say that 52% of couples are not cheating in this way.
Answer:
B
Step-by-step explanation:
I'm pretty sure that the shaded space represents all possible solutions, meaning that the X has to be greater than or equal to 2.

Answer:
(b) Symmetric property of congruence
Step-by-step explanation:
a) The transitive property says if a=b and b=c then a=c
b) The symmetric property says if a=b then b=a
c) The substitution property says if a=b and a=c then b=c
d) The reflexive property says a=a
__
The property of congruence of interest here is the <em>symmetric property</em>.
Say r is rational. Suppose for a second, that s is not. Then, r+s is irrational. But this contradicts the fact that b is rational.
So, if one root is rational, then the other root is also rational
