In a data set with 201 observations, there are 179 observations with values less than 81.2. Find the percentile for 81.2. A) 87th percentile
B) 82nd percentile
C) 85th percentile
D) 89th percentile

d

Step-by-step explanation:

the anwser is d

1) is right

step-by-step explanation:

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 .
