Answer:
Pounds
Step-by-step explanation:
The first step is to find the , mean of the data 6, 4, 8, 7, 8, 9
![\mu= \frac{6 + 4 + 8 + 7 + 8 + 9}{6}\\\\\mu = 7](https://tex.z-dn.net/?f=%5Cmu%3D%20%5Cfrac%7B6%20%2B%204%20%2B%208%20%2B%207%20%2B%208%20%2B%209%7D%7B6%7D%5C%5C%5C%5C%5Cmu%20%3D%207)
Now we find the difference between each data
and the mean . ![|\mu-x_i|](https://tex.z-dn.net/?f=%7C%5Cmu-x_i%7C)
![| 7-6 | = 1\\\\| 7-4 | = 3\\\\| 7-8 | = 1\\\\| 7-7 | = 0\\\\| 7-8 | = 1\\\\| 7-9 | = 2](https://tex.z-dn.net/?f=%7C%207-6%20%7C%20%3D%201%5C%5C%5C%5C%7C%207-4%20%7C%20%3D%203%5C%5C%5C%5C%7C%207-8%20%7C%20%3D%201%5C%5C%5C%5C%7C%207-7%20%7C%20%3D%200%5C%5C%5C%5C%7C%207-8%20%7C%20%3D%201%5C%5C%5C%5C%7C%207-9%20%7C%20%3D%202)
Now we add all the difference and then we divide the result between the data number
:
![MAD = \frac{1 + 3+ 1 + 0 +1 +2}{6}](https://tex.z-dn.net/?f=MAD%20%3D%20%5Cfrac%7B1%20%2B%203%2B%201%20%2B%200%20%2B1%20%2B2%7D%7B6%7D)
Pounds
This value means that the average difference between the weight of each bag and the average weight of the bags is 1,333 pounds.
The mean deviation represents a measure of how scattered the data are with respect to the mean. That is, the DMA measures how much the weight of a bag differs from the average weight of the 6 bags
Arrange the expression into the a + bi form of a complex number.
5/2 * i + (2/3+6i)
Answer:
a/1/$400
Step-by-step explanation:
240 divided by 12=20
20x10x2=$400
A² + b² = c²
11² + 9² = c²
121 + 81 = c²
202 = c²
√202 = c
14.2126704035518955 = c
Rounded 14.2126704035518955 ≈ 14.2
I hope this helps. (:
