The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides. That is, for any triangle ABC, the bisector of the angle at C divides the opposite side into segments of length x and y such that a/b = x/y.

Rewrite each problem so that x appears on only one side
Vlad1618 [11]

Answer:

x = -5/21

Step-by-step explanation:

Step 1: Write equation

2(12x - 1) = (21x - 49)/7

Step 2: Solve for <em>x</em>

  1. Multiply both sides by 7: 14(12x - 1) = 21x - 49
  2. Distribute 14: 168x - 14 = 21x - 49
  3. Subtract 21x on both sides: 147x - 14 = -49
  4. Add 14 to both sides: 147x = -35
  5. Divide both sides by 147: x = -5/21

Problem 2 (4 points) The Better Business Bureau conducts a survey of
Georgia [21]

The probability that all three would recommend their attorney to a friend is 18.19%, and the probability that the first would not, but the second and third would recommend their attorney to a friend is 8.56%.

<h3><u>Probabilities</u></h3>

Since the Better Business Bureau conducts a survey of 30 people who recently hired an attorney, and 17 of them say that they would recommend their attorney to a friend, while 8 say that they would not recommend their attorney to a friend, and the remaining 5 say that they are not sure, and then three people are selected from this group of 30 people at random, to determine what is the probability that A) all three would recommend their attorney to a friend, and B) the first would not, but the second and third would recommend their attorney to a friend, the following calculation must be performed:

A)

  • 17/30 x 17/30 x 17/30 = X
  • 0.5666 x 0.5666 x 0.5666 = X
  • 0.1819 = X

B)

  • 8/30 x 17/30 x 17/30 = X
  • 0.2666 x 0.5666 x 0.5666 = X
  • 0.0856 = X

Therefore, the probability that all three would recommend their attorney to a friend is 18.19%, and the probability that the first would not, but the second and third would recommend their attorney to a friend is 8.56%.
