4/52*20/51

9/38

Step-by-step explanation:

For the first one

4/52*20/51

4/52 - 4 kings out of 52 cards and 5*4=20 numbered cards (1, 3, 5, 7, 9) out of 51 cards (one taken at first step)

For the second one

10/20*9/19= 90/380=9/38

10 green out of 20 marbles, then 9 green out of 19 marbles (one green taken at first step)

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
