Question

Which of the answer choices could be the one missing data item for the following set, if the mode is 12?

Answer 1

Answer:

D

Step-by-step explanation:

first of all, what is mode: it is the highest occuring number in a set of numbers.

now since 12 is supposed to be the mean and it occurs twice but 9 also occurs twice so for 12 to be the mode, we must add one more 12.

therefore the answer is 12

Answer 2

Answer:

12

Step-by-step explanation:

Mode: the number often being occurred

If the mode is 12 then 12 has to be occurred the most in the set otherwise it can’t be the mode

Then we have- but first let’s set up the numbers in oder to not confuse ourselves!

7, 7, 7, 9, 9, 12, 12, 12, 15, 15

Now we can see that 2 numbers (12 and 15) have been occurred the same way!

Since we’re trying to make the mode equal to 12, that one additional number will have to be 12
