To find the mean, you add all the numbers together and then divide by the number of numbers (6).
4 + 12 + 20 + 24 + 32 + 40 = 132
132/6 = 22
To find the mean absolute deviation, you will find the distance between each number and the mean and then divide this by 6 as well.
(22-4) +(22-12)+(22-20)+(24-22)+(32-22)+(40-22)
18 + 10 + 2 + 2 + 10 + 18 = 60
60/6 = 10
The mean absolute deviation is 10.
The correct answer is that Stefano should have divided by 6 when finding the mean absolute deviation.
Answer:
7/22 as a decimal rounded to the nearest hundredths is 0.32.
Step-by-step explanation:
7/22 as a decimal is .31818181818182,the thousandths place is over 5 which makes the hundredths place .01 higher when rounded, making it 0.32.
Your answer is 18 :)
