For cynthia's fourth lab report, she calculated the ratio of velocities before and after the impact of a basketball bouncing on a court. this measurement is called the coefficient of restitution. she got the following four values. 0.72 0.75 0.73 0.76 the accepted value is 0.77. cynthia's percent error was [blank]%. enter your answer as the number that correctly fills in the blank, rounded to two decimal places, like this: 42.53

idk

step-by-step explanation:

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.

the answer is (-4,-4)

hope this ! : d
