Step-by-step explanation:
Hospital A (with 50 births a day), because the more births you see, the closer the proportions will be to 0.5.
Hospital B (with 10 births a day), because with fewer births there will be less variability.
The two hospitals are equally likely to record such an event, because the probability of a boy does not depend on the number of births

Answer :

step-by-step explanation :

This can be rewritten as:

Now,

The law of indices states that:

It implies that, when dividing two expressions with the same bases, repeat one of the bases and subtract the exponents.
Therefore,


Note: Any non-zero number exponent zero is 1
Also

Hence:
Answer:
steps
Step-by-step explanation:
secθ / cscθ + sinθ / cosθ = (1/cosθ) / (1 / sinθ) + sinθ / cosθ
= (sinθ / cosθ) + (sinθ / cosθ) = 2 (sinθ / cosθ) = 2 tanθ
