Suppose that you turn on the hot water, which flows at 8.7 liters per minute into the bathtub. Two minutes later you also turn o

n the cold water, which flows at 13.2 liters per minute. Let x be the number of minutes since you turned on the cold water.
A. Write expressions in terms of x for the number of minutes the hot water has been running, the number of liters the hot faucet has delivered, and the number of liters the cold faucet has deliv- ered.
B. Write an equation stating that the hot and cold faucets have de- livered the same number of liters. Solve the equation to find out when this happens.
C. The tub holds 100 liters. Will it have overflowed by the time the hot and cold faucets have delivered the same amounts? Justify your answer. ​

Dalgliesh the detective fancies himself a shrewd judge of human nature. In careful tests it has been discovered that he is right
Dafna11 [192]

Answer:

The probability that Jones is lying is 6/7

Step-by-step explanation:

First we will list out 2 different cases when the outcome is a lie

1.probability that Jones tells lies is = 0.6 and probability that dalgiliesh analyses it correctly is 0.8

So the probability that dagliesh correctly analyses that he is telling lies is 0.8*0.6=0.48

2.Probability that Jones tells truth is 0.4 and if dagliesh analyses it incorrectly (which has a probability of 0.2) the outcome(as analysed by dagiliesh) is a lie

So probability that dagliesh analyses Jones truth as a lie is 0.2*.0.4=0.08

Total probability of outcome being a lie is 0.48+0.08=0.56

But we need the probability of Jones actually saying a lie which is nothing but 0.48/0.56= 6/7
