A graph that has no breaks in it is called a continuous data
Answer:
It was a 33% decrease
Step-by-step explanation:
90 minutes - 60 minutes = 30 minutes
30/90= .333333333333
Percent change = change/original * 100
(2.65 - 2.30)/ 2.65 * 100
.35/2.65 * 100
13.2 % decrease
-13.2% if you need to write is as a negative
Speed=distance traveled/time of the travel=78/2=39 mph
This one is prime. The sum of two squares doesn't factor.
The more interesting case is q^2-1, which factors into (q-1)(q+1).
