Special Right Triangle

where,

now

applying tan 30°

tan theta = perpendicular/base

=>tan 30° = 6/a

(since tan 30° = 1/√3)

=>1/√3 = 6/a

=> a = 6√3

applying cos Q for finding b

=>cos 60° = b/h

(since cos 60° = 1/2)

=>1/2= 6/b

=> b= 12

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

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.
