If the legs of both triangles are supposed to be proportional then they would be equal in length because that's what proportional means
so if the legs of one triangle are 4.5 and 1.5 then the other triangle "if proportional" would have legs with the same measurements which are 4.5 and 1.5
hope this answers your question
Answer:
Less than 264.44 days would be for the shortest 20%
Step-by-step explanation:
Given that X, the length of a human pregnancy is normally distributed with a mean of 272 days with a standard deviation of 9 days (Bhat & Kushtagi, 2006).
X is N(272, 9)
Corresponding Z score would be for any x

We have to find out the shortest 20%
Corresponding z score i.e. z score 20th percentile is given by
-0.84
corresponding x score is

Less than 264.44 days would be for the shortest 20%
