Answer:
x=−6
Step-by-step explanation:
<u>Step 1: Simplify both sides of the equation.</u>
3x−7-2/3(9x−6)=15
3x+−7+−6x+4=15(Distribute)
(3x+−6x)+(−7+4)=15(Combine Like Terms)
−3x+−3=15
−3x−3=15
<u>Step 2: Add 3 to both sides.</u>
−3x−3+3=15+3
−3x=18
<u>Step 3: Divide both sides by -3.</u>
−3x/−3=18/−3
x=−6
Given :
Two mean absolute value deviation 15.2 and 10.9 .
To Find :
Which mean absolute value deviation represents more consistency 15.2 or 10.9 .
Solution :
First we should know what is mean absolute deviation ( M.A.D) is :
M.A.D of a data set is the average distance between each data value and the mean .
It also describe the variation in a data set .
Also , high variability means the data is spread out and low variability means that data is clustered .
So, low variation means more consistency and vice-versa .
Therefore , 10.9 M.A.D is more consistent .
Hence , this is the required solution .
Answer:
143a + 221b = 1,651
Step-by-step explanation
143a + 221b = 1,651
1.Add the "a"s and "b"s together seperatly.
2.Then put them together in a equation.
3.The a you added together is 143a.The b you added together is 221b.
