Answer:
21ax+4a−12
Step-by-step explanation:
Answer: X = 2
Step-by-step explanation: To find the value of "X" in this equation, we first need to subtract 3 from both sides.

Answer:
The group that has greater value of relative dispersion is the smokers group, as the coefficient of variationof their data is bigger than the coefficient of variation of the non-smokers group data.
CV smokers: 0.387
CV non-smokers: 0.234
Step-by-step explanation:
We will calculate the relative dispersion of each data set with its coefficient of variation (ratio of the standard deviation to the arithmetic mean).
Then, first we calculate the mean and standard deviation for the smokers data:
Mean: 43.7
Standard deviation: 286.5

The mean and standard deviation for the non-smokers is:
Mean: 30.3
Standard deviation: 50.9

Now, we can calculate the coefficient of variation:
CV smokers:

CV non-smokers:

Answer:
Step-by-step explanation:
4/3(6y+21)-17=43
move all terms to the left:
4/3(6y+21)-17-(43)=0
Domain of the equation: 3(6y+21)!=0
y∈R
We add all the numbers together, and all the variables
4/3(6y+21)-60=0
You multiply all the terms by the denominator
-60*3(6y+21)+4=0
multiply elements
