8+2m^3 is your answer. Hope it help!
Answer:
5x+12=42
x=6
Step-by-step explanation:
8+x+x+2+3x+2=42
5x+12=42
5x=42-12
5x=30
x=6
If the mean value of the data set is 509. Then the mean absolute deviation (MAD) for the data set will be 51.5.
<h3>What is the mean absolute deviation?</h3>
It is the average distance between each data point and the mean.
The mean of the following data is 509.
{419, 450, 462, 499, 520, 521, 589, 612}
Then the mean absolute deviation (MAD) for the data set will be

We have
μ = 509
n = 8
Then

-5 1/2 is the correct answer
Answer:
The Final answer will be
with remainder 0.
Step-by-step explanation:
We have attached the division for your reference.
Given:
Dividend = 
Divisor= 
Explaining the division we get;
Step 1: First when we divide the Dividend
with divisor
we will first multiply
with the divisor then we get the Quotient as
and Remainder as 
Step 2: Now the Dividend is
and Divisor is
we will now multiply
with the divisor then we get the Quotient as
and Remainder as 
Step 3: Now the Dividend is
and Divisor is
we will now multiply 2 with the divisor then we get the Quotient as
and Remainder as 0.
Hence The Final answer will be
with remainder 0.
