Answer:
Step-by-step explanation:
The area a total of 4+3+6+5=18 balls, consisting of:
- 4 green
- 3 red
- 6 yellow
- 5 pink
After a green ball is selected (implied that it is not replaced or put back), there will be 17 balls total, consisting of:
- 3 green
- 3 red
- 6 yellow
- 5 pink
Therefore, the probability of drawing another green one is:

<u>Answer:</u>
1/4
<u>Step-by-step explanation:</u>
We are to find the scale factor of the dilation that maps the pre-image of triangle ABC with vertices A(2, 5), B(6, 10) and C(9, −1) to the image triangle A'B'C' with vertices A' (0.5, 1.25), B' (1.5, 2.5), C' (2.25, −0.25).
Center of dilation is at the origin.
To find the scale factor, we will divide the corresponding vertices of the image and pre-image.
A(2, 5) ---> A' (0.5, 1.25) =
B(6, 10) ---> B' (1.5, 2.5) =
C(9, −1) ---> C' (2.25, −0.25) =
Therefore, the scale factor of the dilation is 1/4.
