We want to solve this:
54x + 64 ≥ 49x + 59
First, subtract 49x from both sides and you would get:
5x + 64 ≥ 59
Then subtract 64 from both sides:
5x ≥ -5
Divide both sides by 5:
x ≥ -1
Its C for the answer all it wants is an overlapping congruent
Answer:
When the machine indicates a lie, what is the probability that the suspect is really lying? If the machine does not indicate a lie, what is the probability that the suspect is really telling the truth?
My solution if the probability that a test subject is chosen at random from the 200 in fact lie = 80/(80+5)=0.94
Then when 15% of people arrested lie, the probability that the suspect is really lying is 0.15*0.94=0.141
Step-by-step explanation:
Speed=distance/time
suppose the distance of the first day is d, and the time is t
distance of the second day: d+0.17d=1.17d
time of the second day: t+0.2t=1.2t
speed of the second day: 1.17d/1.2t=0.975(d/t)=(1-0.025)(d/t)
so the speed of the second day is 2.5% slower than the first day.
