On the basis of data from a study conducted by the university of colorado school of medicine at denver, the percentage of women receiving regional analgesia (epidural pain relief) during childbirth at small hospitals between 1981 and 1997 can be modeled as p(x) = 0.73(1.2912x) + 8 percent where x is the number of years since 1980.

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.

unless if u could do my questions, if not i wouldn't want to

cluster sampling.

step-by-step explanation:

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
