The lengths of a particular animal's pregnancies are approximately normally distributed, with mean muequals265 days and standard deviation sigmaequals12 days. (a) What proportion of pregnancies lasts more than 274 days?(b) What proportion of pregnancies lasts between 259 and 271 days? (c) What is the probability that a randomly selected pregnancy lasts no more than 253 days?(d) A "very preterm" baby is one whose gestation period is less than 235 days. Are very preterm babies unusual?

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

da freeck kinda math is this just drop out

step-by-step explanation:

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0
