Answer:
The driving time at 54 miles per hour is 37.04 hours.
The driving time is at 75 miles per hour is 26.67 hours.
The gasoline cost at 54 miles per hour is $201.82
The gasoline cost at 75 miles per hour is $302.73
Step-by-step explanation:
Suppose your car averages 33 miles per gallon on the highway if your average speed is 54 miles per hour,
and it averages 22 miles per gallon on the highway if your average speed is 75 miles per hour.
The driving time for a 2000-mile trip if you drive at an average speed of 54 miles per hour = Distance / Speed = 2000 / 54 = 37.04 hours.
The driving time for a 2000-mile trip if you drive at an average speed of 75 miles per hour = Distance / Speed = 2000 / 75 = 26.67 hours.
Assume a gasoline price of $3.33 per gallon.
The gasoline cost for a 2000-mile trip if you drive at an average speed of 54 miles per hour = (Distance / Gas mileage) * Cost = (2000/33)*3.33 = $201.82
The gasoline cost for a 2000-mile trip if you drive at an average speed of 75 miles per hour = (Distance / Gas mileage) * Cost = (2000/22)*3.33 = $302.73
Answer:
The probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47
Step-by-step explanation:
Has Gained Weight Has Not Gained Weight
Does not take vitamins 52 19
Takes one vitamin per day 35 49
Takes more than one vitamin per day 72 80
We are supposed to find the probability that he or she has gained weight, given that he or she takes more than one vitamin per day
A= he or she has gained weight
B=he or she takes more than one vitamin per day
![P(A|B)=\frac{P(A \cap B)}{P(B)}](https://tex.z-dn.net/?f=P%28A%7CB%29%3D%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7BP%28B%29%7D)
![A \cap B = 72](https://tex.z-dn.net/?f=A%20%5Ccap%20B%20%3D%2072)
B = 72+80=152
So,![P(A|B)=\frac{72}{152}=0.47](https://tex.z-dn.net/?f=P%28A%7CB%29%3D%5Cfrac%7B72%7D%7B152%7D%3D0.47)
So, Option C is true
Hence the probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47
