Brenna is constructing a circle inscribed in a triangle. she has partially completed the construction, as shown below. what should be her next step in the construction? triangle abc is shown with arc markings on side ab and bc and two intersecting arc markings across from angle b and again across from angle c. there is a line drawn from angle b through the two intersecting arc markings as well as from angle c to the other set of two intersecting arc markings. connect vertex b to the arc marking to complete the angle bisector find the angle bisectors for angles a and b connect three arc markings together to form the triangle use the incenter to determine the center to construct the circle

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages

i would love   to but there is no graph shown
