Answer:
v_0(initial velocity) v_f(final velocity) a(acceleration)
v_0=70 km/h v_f= 0 km/h( rest)
Kinematics equation is a=(v_f-v-0)/time
a=(0-70)/(7/3600) which means it decelerates at -36000 km/h
This number is humongous; I would advise you to re-check the problem and see if the the time it takes is 7 hours rather than 7 seconds. Notice that I put the time as 7/3600 because it is 7 seconds which should be converted to hours.
the Great Common factor can either be 3 or x.
The answers to the questions
Answer:
P( B | A) will actually be the probability of the polygraph test being wrong.
Step-by-step explanation:
The event A represents the event that the subject is telling the truth.
The event B represents the event when he fails the polygraph test, which is indicative of the fact that he is lying.
The notation P( B | A) describes the probability that the subject fails the polygraph test given that he is actually telling the truth.
So in retrospect P( B | A) will actually be the probability of the polygraph test being wrong.
1/4 times 2 2/3 = 2/3
Change from a mixed number to improper fraction: 1/4 times 8/3
Multiply across so 1x8/4x3 to get 8/12
Simplify to 2/3
