A) The probability that there are no boys in the car is given by:
"The domain is the set of all first elements of ordered pairs (x-coordinates).The range is the set of all second elements of ordered pairs (y-coordinates).Only the elements "used" by the relation or function constitute the range.
Answer:

Step-by-step explanation:
Looking at the angles, we can see that this is a 30-60-90 triangle.
The side that is with the 30° angle and the 90° angle is represented by
.
So let's find x.

Divide both sides by
:
.
Now the hypotenuse is always
(the leg with the 90° and 60° is just x.) So,
.
Hope this helped!
Answer:
5 x 4 = 20, 20 x 1/2 (basically just dividing by 2) = 10
10 x 3(width) = 30 inches is your answer.
