b. A doctor records the age of a patient and his weight every 6 months.
c. Max is saving for a new game. He has $10 and saves $5 each week.
d. Both A and C.
e. All of the above.

Answer 1

Answer:

Option d is correct.

Step-by-step explanation:

Discrete values are those which take an integer value not in fraction.

Option A is discrete because there will be certain number of students in class say 20 or 30

We can not have 20.5 students

Therefore, option a is correct.

Option B is not discrete because many people can have age say 65 and a half years and weight can be in decimals say 50.5 kgs.

Option C is correct because he is saving a proper integer number of money.

Therefore, option d is correct that is both A and C are correct.
