in a random sample, 328 out of 920 12th graders in california smoked marijuana within the last year. answer questions 1-4, and round to 3 decimal places.

don't understand the question what do you need exactly ?

Step-by-step explanation:

add 5 subtract 1

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 .
