The lengths of a particularâ animal's pregnancies are approximately normallyâ distributed, with mean muî¼equals=270270 days and standard deviation sigmaïequals=2020 days. â(a) what proportion of pregnancies lasts more than 275275 âdays? â(b) what proportion of pregnancies lasts between 255255 and 285285 âdays? â(c) what is the probability that a randomly selected pregnancy lasts no more than 230230 âdays? â(d) aâ "very preterm" baby is one whose gestation period is less than 240240 days. are very preterm babiesâ unusual?

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 .

the first option is the answer.
