Answer:
2.18
Step-by-step explanation:
The mean is the most familiar average. It is defined as a value obtained by dividing the sum of all observations by their number. It is calculated as
Mean = Sum of all the observations/ Number of the observations
Mean= x₁+x₂+...............+xₐ/n
Where x₁,x₂,...............,xₐ refer to different values of x and n is the sample size.
Mean= 2+1+2+2+2+2+1+3+3+3+3/11= 24/11= 2.18
The mean may correspond to a population or a sample from a population.
The population mean is a fixed quantity where as the sample mean is a variable quantity because different samples from the same population tend to have different means.
Answer:
-2
Step-by-step explanation:
The equation is -12/c=6
by solving for c you get,
-12/c=6
Then multiply both sides by the LCM c to get, -12=6c
Divide both sides by 6 to get,
-12/6=6c/6
-2=c
Verification:
-12/-2=6 since when a negative number divides a negative number the answer is a positive value
Answer:
b=5
Step-by-step explanation:
2+b=7
Subtract 2 from each side
2+b-2=7-2
b= 5
Answer
4+(-x),-x+4
Step-by-step explanation:
Hi!
To find the range of possible values of x, we have to side 1 from side 2...
7.1 - 5.6 = 1.5
The smallest side x could be is 1.5.
Now add side 1 to side 2
7.1 + 5.6 = 12.7
The biggest side x could be is 12.7
So x could be anywhere from 1.5 to 12.7 (or, 1.5 < x < 12.7)
Hope this helps! :)
