Answer:
0.3 chance of not drawing a blue marble.
Step-by-step explanation:
This problem can be found using the theoretical probability formula.
The formula is: P (desired outcome) = <u># of desired outcomes</u>
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>
10
3/10 is equal to 0.3 as a decimal.

Answer:
The answer is below
Step-by-step explanation:
A tangent is a line which touches a circle at one point. The angle between a tangent and a circle is 90°.
The two tangent theorem states that tangent that meet at the same point are equal in length.
Therefore:
CD = c + d
but c = 5.1, hence:
CD = 5.1 + d
12.1 = 5.1 + d
d = 7
AD = a + d; but AD = 12.2, d = 7
12.2 = a + 7
a = 5.2
AB = a + b; but b = 3.3
AB = 5.2 + 3.3 = 8.5
BC = b + c = 3.3 + 5.1 = 8.4
Perimeter of ABCD = AB + BC + CD + AD = 8.5 + 8.4 + 12.1 + 12.2 = 41.2
