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:
<u>m<ABC=42</u>
Step-by-step explanation:
This image shows the majority of the math and all you do to get to that point is add 5x+13 and 3x+33 so you can find x which you will need to complete the equation for m<ABC, and you know they equal 70, which means all you have to do is take 8x+46=70 and work it out giving you x=3. then you can find m<ABC by pluging in 3 to the equation 3x+33, so 3*3=9, and 9+33=42, so your answer is m<ABC=42
