Answer:
The correct option is 3. The green figure is similar to the 9 by 6 figure.
Step-by-step explanation:
Let a small square represents 1 unit.
From the given figure it is noticed that
1. The dimensions of red figure is 4 by 3.
2.The dimensions of brown figure is 4 by 6.
3.The dimensions of green figure is 2 by 3.
3.The dimensions of purple figure is 3 by 6.
The dimensions of given figure is 9 by 6. The proportion of its dimensions is

The corresponding sides of two similar figure are proportional. It means the ration of sides must be
.
The dimensions of green figure is 2 by 3. It means the proportion of its dimensions is
.
Therefore the correct option is 3. The green figure is similar to the 9 by 6 figure.
Step-by-step explanation:
×=100
1. Divded 35 by 14 and u get 0.4
2
Divided 40 by 0.4 and u get 100
Mean = 60 / 4 = 15
13 - 15 = -2
17 - 15 = 2
9 - 15 = -6
21 - 15 = 6
Total of squares = 4 + 4 + 36 + 36 = 80
because this is a sample we divide this by n - 1 ( = 3)
Standard deviation = sqrt (80/3) = 5.16 answer
