Explanation:

Start with:

cot

x

−

√

=

0

cot

x

=

√

3

This means that:

cos

x

sin

x

=

√

3

1

So the adjacent is length  

√

3

and the opposite is length 1. This set us up for the 30/60/90 triangle and the angle we're looking at is the  

30

o

or  

π

6

one.

So now the question is which quadrants are we looking at. Cotangent is positive in Q1 and Q3. The angles we're looking at, then, are  

π

and

This question does not limit our answer to any particular domain, and so we need the general solution, which is:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

the answer is $42.96
