X/Hr and they want number of female customers in the same hours Y/Hr.
They give you two variables and they want you to find the probability of two variables X and Y is there more to the Question? what are they asking?
Unfortunately your response would only be true if CD was perpendicular to AB. However we don't know if CD is perpendicular or not. So we don't have enough information. The actual answer is choice E) None of these.
The time that will be taken for Daniel to swim to the boat ramp will be 3.34 minutes.
<h3>How to calculate time taken</h3>
Let the distance be x.
Based on the information given, the calculation will be:
Sin 53° = 400/x
0.7986 = 400/x
x = 500 feet
Time = Distance / Speed
Time = 500/150 = 3.33 minutes.
The distance of the boat ramp from the campsite will be:
Cos53° = y/500
0.60 = y/500
y = 300 feet.
Distance will be:
= 1600 - 300 = 1300 feet
The minutes that it takes him to jog from the boat ramp to the campsite will be:
Distance = 1300 feet
Rate = 4 miles per hour = 352 feet per minutes
Time = Distance / Rate
Time = 1300/352 = 3.69 minutes
The total time taken will be:
= 3.33 + 3.69
= 7.02 minutes

Answer:
- p(12 are truthful) ≈ 0.0687
- p(≥ 1 are not) ≈ 0.9313
Step-by-step explanation:
The probability the test says 1 is truthful is 0.8, so the probability that all 12 will be judged truthful is ...
0.8^12 ≈ 0.0687
The probability that at least one will be judged untruthful is the complement of this:
1 - 0.0687 = 0.9313
The probability that the lie detector says all 12 are truthful is about 0.0687.
The probability that lie detector says at least 1 is deceptive is about 0.9313.
