Answer:
January has the greater MAD.
Step-by-step explanation:
The MAD of January is 8. You can figure this out by finding the mean of the data (adding them all together then dividing by the number of data points), then finding the distance between each data point and the mean. You then will add all the distances together, then divide by the number of data points. The MAD of July is 2.5. See above for the process.

Mr. Jackson invested $800 at 6% per year and $ 2400 at 4 % per year
<h3><u>Solution:</u></h3>
Mr. Jackson invested a sum of money at 6% per year, and 3 times as much at 4% per year.
Let the sum invested be ‘a’ and ‘3a’ at 6% per year and 4 % per year respectively
Also, his annual return totaled $144
We can form following equation on the basis of question:-
![\begin{array}{l}{\text { Then, } \frac{a \times 6 \times 1}{100}+\frac{3 a \times 4 \times 1}{100}=\$ 144} \\\\ {\frac{6 a}{100}+\frac{12 a}{100}=144} \\\\ {\frac{6 a+12 a}{100}=144} \\\\ {\frac{18 a}{100}=144} \\\\ {18 a=14400} \\\\ {a=14400 \div 18}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%5Ctext%20%7B%20Then%2C%20%7D%20%5Cfrac%7Ba%20%5Ctimes%206%20%5Ctimes%201%7D%7B100%7D%2B%5Cfrac%7B3%20a%20%5Ctimes%204%20%5Ctimes%201%7D%7B100%7D%3D%5C%24%20144%7D%20%5C%5C%5C%5C%20%7B%5Cfrac%7B6%20a%7D%7B100%7D%2B%5Cfrac%7B12%20a%7D%7B100%7D%3D144%7D%20%5C%5C%5C%5C%20%7B%5Cfrac%7B6%20a%2B12%20a%7D%7B100%7D%3D144%7D%20%5C%5C%5C%5C%20%7B%5Cfrac%7B18%20a%7D%7B100%7D%3D144%7D%20%5C%5C%5C%5C%20%7B18%20a%3D14400%7D%20%5C%5C%5C%5C%20%7Ba%3D14400%20%5Cdiv%2018%7D%5Cend%7Barray%7D)
a = $800
The amount of money invested at 6% = a = 800
The amount of money invested at 4 % = 3a = 3(800) = 2400
So, the amount of money invested at 6% is $800 and the amount of money invested at 4% is $ 2400
