The sum of 63 plus 63 is 126. This can be calculated by adding the two numbers together using the standard addition method, where you add the digits in each place value column starting from the right. In this case, adding the ones column (3 + 3) gives 6, and adding the tens column (6 + 6) gives 12, resulting in the final answer of 126.
some_number ÷ 6 = 63 → some_number = 63 x 6 = 378

Step 1: Find the mean Step 2: Find the deviation from the mean Step 3: Take the absolute value of the deviation Step 4: Find the mean of the absolute deviation. x----x-mean 63 63-63 0 69 69-63 6 62 62-63 -1 57 57-63 -6 64 64-63 1 mean = (63+69+62+57+64)/5 = 63 Taking the absolute deviations, we have 0,6,1,6,1 Averaging these deviations : (0+6+1+6+1)/5 =14/5 = 2.8 Mean absolute deviation = 2.8
