Simplify. cot x
CSC X
Use algebra and the fundamental trigonometric identities.
Your answer should be a number or use a single trigonometric

Cosx is the answer.

Step-by-step explanation:

We have to simplify the trigonometric fraction given in this question.

Further we can rewrite this ratio in the simplified form.

Since, Cot x = and Cosec(x) =

Now substitute these simplified forms of Cotx and Cscx in the given fraction.

=

      =

      = Cosx

Therefore, Cosx will be the answer.

the correct answer is 1: 2

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
