(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?

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
