Answer:
The answer to your question is: letter D
Step-by-step explanation:
The interval graph is (5, 9] , open five, nine close. As an inequality this interval is:
5 < x ≤ 9
a) Letter A is incorrect because it suggests that two sections in the graph must be shaded and in this graph there is only one section shaded.
b) Letter B is incorrect because in the graph we observe that before 5 there must be a parenthesis because the point is open and the point in 9 is shaded so it must be follow by a ].
c) Letter c is alos incorrect because it suggests two sections shaded in the graph and it shows only one.
Answer:
the radius is something in math
Answer:
Answers are given below.
Step-by-step explanation:
a) one-to-one correspondence between the set of positiveintegers and that set.
Whenever we have one to one correspondence with positive integers, the set is countable and here infinite.
b) integers divisible by 5 and not 7
..This set is all integers divisible by 5 but not by 7. This is a discrete set and hence countable and infinite.
c) the real numbers with decimal representationsconsisting of all 1’s
-- This cannot be counted and hence uncountable but infinite.
d) the real numbers with decimal representationsconsisting of all 1’s or 9’s
-- This is also uncountable but infinite.
