Below are three boxes containing black and white balls. The number of each color is noted inside the box. Draw a ball from box one and place it in box 2. Then draw a ball from box 2 and place it in box 3. Finally draw a ball from box 3. Box one 6 white 3 black box 2 3 white 3 black box 3 3 white 1 black what is the probability that the last ball drawn from box 3 is white

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12

If is congruent to,then m is the midpoint

The solution of the system of linear equations is b. (2,-3) because the solution is the poi (point of intersection)
