Consider how you would begin to calculate the probability that this would happen, going into any 10 year period for a regular lottery player? What do you need to know? If winning the lottery multiple times is a compound event, what other probabilities would be used to make this calculation?

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
