Given : The mileage per day is distributed normally with
Mean :
Standard deviation :
Let X be the random variable that represents the distance traveled by truck in one day .
Now, calculate the z-score :-
For x= 132 miles per day.
For x= 159 miles per day.
Now by using standard normal distribution table, the probability that a truck drives between 132 and 159 miles in a day will be :-
Hence, the probability that a truck drives between 132 and 159 miles in a day =0.1824
Answer:
The unit rate is:
- 1/8 turkey/per hour.
Step-by-step explanation:
As Chet was eating 1/4 of a turkey every 2 hours.
This tells us that every two hours, Chet will eat 175 1/4 of a turkey.
- Unit rate basically means 'how much of something per 1 unit of something else'.
A unit rate is a rate with a denominator of 1 unit.
This means, in 1 hour, Chet will eat half of what he eats every 2 hours.
so Chet will eat of a turkey in 1 hour.
i.e.
Therefore, the unit rate is:
- 1/8 turkey/per hour.
