Answer:
4/3
Step-by-step explanation:
A proportional relationship is a relationship that crosses through the origin or (0,0). This means the slope of the line can be found by subtracting the points (12,16) and (0,0) in the slope formula.
So the slope is 4/3 and must be the value between any two points on the line.
This means the function moves from (0,0) to (1, 4/3).
Answer:
0.3888
Step-by-step explanation:
To solve the exercise we need a neutral time, so we define at 12:00 as time 0.
If the man arrives in a uniformly distributed time between 11:40 and 12:10, the time is distributed from -20 to 10.
If the woman arrives in a time evenly distributed between 11:45 and 12:20, the time is distributed from -15 to 20.
Assuming that each one arrives at 12: X and 12: Y for men and women, then the space of our time is defined as
Man [-20,10]
Woman [-15,20]
So,
Then,
The probability of finding an arrival less than 5 minutes is
