Answer:
Step-by-step explanation:
Let X be the lengths of a particular animal's pregnancies
X is N(252, 20)
(a) What proportion of pregnancies lasts more than 262 days?

(b) What proportion of pregnancies lasts between 227 and 257 days?

(c) What is the probability that a randomly selected pregnancy lasts no more than 237 days?
P(X<237) = 0.2266
(d) A "very preterm" baby is one whose gestation period is less than 202 days. Are very preterm babies unusual?

Yes very unusual since probability is very near to 0.
We have been given that the label on a can of lemonade gives the volume as 12 fl oz or 355 ml and we are asked to verify that these two measurements are nearly equivalent.
Since we know that 1 fluid ounce equals 29.5735 ml. Let us find volume of lemonade can in ml by multiplying 12 by 29.5735.



We can see that 354.882 is nearly equivalent to 355. Therefore, we can say that these two measurements are nearly equivalent.
3/5 times 3/5 times 3/5 times 3/5 is the area. all sides are the same on a square
