Answer:
2
Step-by-step explanation:
√(1 - cos^2x) = sin x
and
√(1 - sin^2x) = cos x
So the expression becomes:
sin x / sin x + cos x / cos x
= 2
Answer:b
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
We equate both the y's and solve for x algebraically:

Now taking the value x= 14 and putting it in the 1st equation would give us y:

Hence the solution is (14,8), answer is D
There are total 4 outcomes
We can get:
Head, Head
Head, Tail
Tail, Head
Tail, Tail
So, tossing 2 coins, result in 4 possible outcomes which make the sample space.
So correct answer is option B
