Each side of the square is 9cm
The experimental probability that the next wooden box will be flawed is 
<u>Explanation:</u>
Given:
2 out of 12 wooden boxes is flawed.
Experimental probability that the next wooden box will be flawed = ?
If next wooden box is inspected, the total number of wooden box checked will be 12 + 1 = 13
If the next wooden box is flawed, then the number of flawed boxes would be 2+1 = 3
Thus, the experimental probability that the next wooden box will be flawed is 
Answer:
I don't know how helpful I'll be, sorry :(
Step-by-step explanation:
So the scale factor is 1/4 reduction because the triangle P'Q'R' is smaller than the original. When reflecting the triangle P'Q'R' over the Y axis, you'll have P"Q"R". The graphing might be a little confusing but it's just a vertical reflection.
P" = (-1,0)
Q"= (0,-1)
R"= (2,-1)
Triangles PQR and P"Q"R" are not congruent because P"Q"R" has had a 1/4 reduction and a vertical reflection.
