25/100 = 1/4 (divide both numerator and denominator by 25)
350/1000 = 35/100 = 7/20.

Step-by-step explanation:
Answer: 2.28 %
Step-by-step explanation:
Given : Mean : 
Standard deviation :
The formula to calculate the z-score :-
For x = 72
The p-value = 
In percent, 
Hence, the percentage of pediatricians work more than 72 h per week = 2.28 %
w is the width and it is the independent variable. You can pick any positive whole number you want (within reason of course; you can't go to infinity or go beyond some set boundary). Whatever you picked for w, the expression 2w-5 will be dependent on it. So the length is dependent on the width.
For instance, if the width is w = 10 feet, then 2w-5 = 2*10-5 = 20-5 = 15 feet is the length. The choice of 10 feet for the width directly affects the length being 15 feet.
