statuscvo [17]

Answer:

0.3 chance of not drawing a blue marble.

Step-by-step explanation:

This problem can be found using the theoretical probability formula.

                                                             total number of outcomes

Now all you have to do is input the numbers into the equation.

P(not drawing a blue marble) = <u>3</u>

Answer:

198\ ft^2

Step-by-step explanation:        

see the attached figure to better understand the problem

we know that the area of the room is equal to the area of a rectangle plus the area of a trapezoid

step 1

Find out the area of the rectangle

A_1=(18)(9)=162\ ft^2

step 2

Find out the area of the trapezoid

A_2=\frac{1}{2} (9+3)(6)=36\ ft^2

step 3

Sum the areas

A=A_1+A_2

substitute the values

A=162++36=198\ ft^2
