Yes because each output (y) has a unique input (x).
we know
distance =time *speed
from given question we have following equation
4*t+(1.5-t)*8=10
4*t+12-8t=10
12-4t=10
-4t=10-12
4*t=2
t=0.5 hour
hence at speed 4 miles per hour he crosses 4*0.5=2 miles
at speed 8 miles per hour he crosses 8*(1.5-0.5)=8 miles
Answer:
5/8
Step-by-step explanation:
1/4=2/8
7/8-2/8=5/8
The population would be the total number of customers found in the database.
The sample would be BIASED because the computer will be identifying the 600 most loyal customers from the database.
