Which is an equation for the circle?

Option D.

Step-by-step explanation:

From the given graph,

Center of the circle = (-4, -2)

This circle passes through a point (0, -3),

Radius of the circle = Distance between center and point (0, -3)

r =

r =

Standard equation of the circle is,

(x - h)² + (y - k)² = r²

Where (h, k) is the center and r is the radius of the circle.

By putting the values in this equation,

(x + 4)² + (y + 2)² = (√17)²

(x + 4)² + (y + 2)² = 17

Option D. will be the answer.

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

1. sometimes

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
