Answer:
5 flowers are pink
Step-by-step explanation:
Answer:
The answer is "1.448 miles".
Step-by-step explanation:
X= The distance to both the nozzle clogged from of the starting point.
X
Uniform(0,2) miles.
They are simulating the random number Y=0.724, and the Y has both a distribution uniform(0,1). Therefore 2Y is distributed evenly (0.2). And They model the clogging of its nozzle at 2Y=1.448 miles
