What is the mean absolute deviation of the data set? {12, 10, 10, 8, 6, 7, 7, 12}

The MAD of  {12, 10, 10, 8, 6, 7, 7, 12} is 2.

Step-by-step explanation:

Step 1 : Add all the values Up:

Step 2 : Divide them by the number of items or numbers:

Step 3: Find the absolute deviations:

Step 4: Add all the absolute deviations:

Step 5: Find the mean:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

answer is 33
