Answer: The right answer is (A).
Step-by-step explanation:
Let X be the daily waste amount produced. X is distributed in a way that is close to Normal with an average of 348.5 pounds and a standard deviation of 38.2 pounds.
P(X > 350) = Normalcdf(lower: 350, upper: 1000, mean: 348.5, SD: 38.2) = 0.484.
The outcome is $7.54 for each book.
By adding 1137.5 and 1500, you obtain 2637.5.
Then, dividing 2637.5 by 350 gives 7.54.
Verifying the result
350 multiplied by 7.54 equals $2639.
Subtracting $1137.5 from $2639 results in $1501.5 (profit).
In the ratio of miles traveled, Mr. Storey and Mrs. Storey's journey is represented as mr: mrs = 3: 1. The total of these ratio units equals 4 (3+1), which means each unit corresponds to 3200 divided by 4, resulting in 800 miles. Mr. Storey drove 3 multiplied by 800, equating to 2400 miles, while Mrs. Storey drove 1 multiplied by 800, totaling 800 miles.
