Answer:

r= 1/2

Step-by-step explanation:

Subtract  7   from both sides of the equation

2 + 7 = 1 6

2 + 7 − 7 = 1 6 − 7

Simplify

2 = 1 6 − 7

Subtract  16r  from both sides of the equation

2 = 1 6 − 7

2 − 1 6 = 1 6 − 7 − 1 6

Simplify

-14r= -7

Divide both sides of the equation by the same term

− 1 4 = − 7

-14r=-7

− 1 4 − 1 4

Simplify

r= 1/2

Answer:

Probability that the measure of a segment is greater than 3 = 0.6

Step-by-step explanation:

From the given attachment,

AB ≅ BC, AC ≅ CD and AD = 12

Therefore, AC ≅ CD = \frac{1}{2}(\text{AD})

                                  = 6 units

Since AC ≅ CD

AB + BC ≅ CD

2(AB) = 6

AB = 3 units

Now we have measurements of the segments as,

AB = BC = 3 units

AC = CD = 6 units

AD = 12 units

Total number of segments = 5

Length of segments more than 3 = 3

Probability to pick a segment measuring greater than 3,

= \frac{\text{Total number of segments measuring greater than 3}}{Total number of segments}

= \frac{3}{5}

= 0.6
