Sqrt(220)= sqrt(2•2•5•11)=2 sqrt (5•11)=
2 sqrt(55)
So no the radical was not in it’s simplest form
<span>1/3 (6ab - 9b) + 2/3(9ab + 12b)
=</span><span>2ab - 3b + 6ab + 8b
= 8ab + 5b
= b(8a + 5)
hope that helps</span>

You have to evenly divide 45 paper clips into 5 different containers.
45÷5=9
Using it's concept, it is found that the mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.
<h3>What is the mean absolute deviation of a data-set?</h3>
- The mean of a data-set is given by the sum of all observations divided by the number of observations.
- The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.
- The mean absolute deviation represents the average by which the values differ from the mean.
In this problem, the mean is given by:
M = (65 + 58 + 64 + 61 + 67)/5 = 63.
Hence the mean absolute deviation is given by:
MAD = (|65-63| + |58-63| + |64-63| + |61-63| + |67-63|)/5 = 14/5 = 2.8.
The mean absolute deviation of 2.8 means that the heights differ from the mean by an average of 2.8 inches.
