Answer:
integers are closed under division
Step-by-step explanation:
Integers are not closed under division.Let us consider two integers i and j.
Then ![\[\frac{i}{j}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7Bi%7D%7Bj%7D%5C%5D)
need not necessarily be an integer. For example, 2 and 3 are integers but ![\[\frac{2}{3}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B2%7D%7B3%7D%5C%5D)
is not an integer. So the first option , namely, integers are closed under division is not true.
On the other hand, the remaining three options given are correct.
A= 1.142 m/hr
Width of beach at 8 p.m. = 36 m
Width of beach at 3 a.m. = (36-8) m =28 m
Average change in width(A) = change in width (Width of beach at 8 p.m.-Width of beach at 3 a.m.0/ time in hours
A= ( 36-28)/ 7
A= 8/7 m/hr
A = 1.142 m /hr
