You are randomly picking a number between 1 and 20, inclusive. What is the probability of selecting a perfect square?

Answer is 20% chance. (20/100 or 4/20)

Step-by-step explanation:

There are 4 perfect squares in a number set 1-20.

1,4,9, and 16.

So that is 4/20. I multiplied the fraction by 5 to get 20/100 to get 20%

the image of (6, 9) under a dilation is (4, 6). the scale factor is

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
