Answer: 14</h3>
================================
Explanation:
The two angles shown are a linear pair. They are adjacent and supplementary.
Supplementary angles add to 180
(8x+1) + (4x+11) = 180
8x+1+4x+11 = 180
(8x+4x) + (1+11) = 180
12x+12 = 180
12x+12-12 = 180-12 ... subtract 12 from both sides
12x = 168
12x/12 = 168/12 ... divide both sides by 12
x = 14

Answer:
P (T) = 1/4
P ( T | F ) = 1/2 = P(F)
The events are not independent.
Step-by-step explanation:
Let F the event of picking the white ball first
P (F)= 1/2 ( picking the white ball first)
Let T be the event of getting the white ball twice,
P (T) = P( getting white ball) * P( getting white ball)
=( 1/2)*(1/2)
= 1/4
Here P(T∩F) = P(T) because the probability of getting the white balls is the same as probability of getting the white ball first both the times.
P ( T | F ) = P (T∩F)/ P(F)
= (1/4)/ (1/2)
= (1/2)
= 1/2 = P(F)
For the events to be independent the conditional probability P ( T | F ) must be equal to P(T).
Hence the events are not independent.
