Answer:
the probabilities will be following
P(B) = 8/12
P(RIB) = 4/11
P(BNR)= 8/33
probability that the first ball chosen is black and the second ball chosen is red is about = 24 %
Answer:
yes
Step-by-step explanation:
15.3-7.9=7.4
Answer:
It Is The 3rd Choice, Y = -1/4( 4x - 8)
Step-by-step explanation:
This Is Becuase -1/4 times 4x is -1x which is negative x. Then -1/4 times -8 is 2.
Do not listen to the answer below it is wrong.

Step-by-step explanation:
Answer:
<h2>12</h2>
Step-by-step explanation:
If the Quadrilateral A has side lengths 6, 9, 9, and 12 respectively and Quadrilateral B is a scaled copy of A with its shortest side of length 2, then to determine the scale used, we will find the ratio of the shortest side of quadrilateral A to that of quadrilateral B as shown;
ratio of shortest side
B:A = 2:6 = 1:3
This means that the quadrilateral B is 3 times smaller than A.
To find the perimeter of quadrilateral B, we will add all the side length of A and divide by 3 to get the perimeter of quadrilateral A by 3 as shown;
Perimeter of quadrilateral B = (Perimeter of quadrilateral A)/3
Perimeter of quadrilateral A = 6+9+9+12
Perimeter of quadrilateral A = 36
Perimeter of quadrilateral B = 36/3
Perimeter of quadrilateral B = 12
<em>Hence the perimeter of quadrilateral B is 12</em>
