List the elements of the set, then indicate the cardinality of the set. HINT [See Example 2.] (Enter your answers as a comma-separated list. Enter your answers from smallest to largest.) A = {k | k is a positive integer and 8 < k < 16}.

Respuesta :

Answer:

Elements of the set: 9,10,11,12,13,14,15

Cardinality of the set: 7

Step-by-step explanation:

Firstly the set describes that A contains the values of k which are positive integers only.

Secondly it limits the values of k to be between 8 and 16, exclusive of both upper and lower limits.

Therefore we list all positive integers between 8 and 16 i.e. 9,10,11,12,13,14,15

Finally, we count the numbers of elements in the set which is also known as cardinality of the set i.e. 7 for our given set.
