Answer:
28.5
Step-by-step explanation:
i think itś 28.5 because 285 is after an increase of 10% which would mean 28.5 was the increase
150 x 5= 750
20 x 5= 100 ... so they should expect 100 cellphones to be defective
So Mean Absolute Deviation or MAD for short is the Mean of how far each digit is from the Mean. So first find the mean, then for each number so let's say the mean is 3 and the numbers are 2, 4, 3. So 3-2=1, 4-3=1, 3-3=0. So you have 1, 1, 0. Find the mean of that 1+1+0=2/3 so the MAD is 2/3.
So just follow my steps
1. Find the mean
2. Find the difference from the mean of each number
3. Find the mean of step 2
4. Step 3 is your answer
