The missing numbers would be 12-6
X=-4 you have to substitue first so you put the equation where the X is and then you would distribute and then add the numbers that have the common exponent
It might be step 4 where it got dropped by step 3
The mode is the value from a given set of data that occurs most often. It is the data with the highest frequency.
Given:
16,12,10,15,7,9,16
Form the above data given;
Rearranging for easy identification, we have;
7,9,10,12,15,16,16

From the above, we can deduce that the mode is 16 because it appears the most often. It appears twice.
Therefore, the mode is 16.
