Apen is dropped on a hardwood floor and a 1 is recorded if the pen crosses a line and a 0 if it does not. estimate the probability that the pen crosses a line in a single drop. 1 1 1 0 1 0 0 1 0 0 1 1 1

a. 3/13

b. 5/13

c. 5/8

d. 8/13

D. 8/13

Step-by-step explanation:

Of the 13 drops, the pen crossed a line 8 times (there are 8 1's).  So the probability is 8/13.

step-by-step explanation:

goog be able to you with that maybe

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
