Between the median and the number before it and everything in front of it is the lower quartile
The air plane is rising so the change in elevation is +1000 feet. The temp dropped and is -20 degrees fahrenheit.
1 degree per 50 ft
For every 1,000 feet that it climbs, the outside temperature drops 20 ... What is the rate of temperature change in degrees Fahrenheit per foot.
The correct answer is 2/3.
This is a Bayes Theorem Problem
P(oil | negative test) P(negative test)= P(negative test | oil) P(oil)
P(oil | negative test) = P(negative test | oil) P(oil) / P(negative test)
P(oil | negative test) =P(negative test | oil) P(oil) / ( P(negative test | oil) P(oil) + P(negative test | no oil) P(no oil) )
We're given the prior probability of oil, P(oil)=.45, so P(no oil)=.55
We given P(negative test | no oil) = 0.80, so P(negative test | oil) = .20

Choice A
Answer:
After 5 minutes, the submarine is at -40 × 5 = -200 feet
Step-by-step explanation:
In 1 minute, the submarine is 40 feet below sea level. This situation can be represented with -40 feet. Notice that we use a negative sign since the submarine is descending.
