Answer:
4
Step-by-step explanation:
Total circle = 360°
1/2 of circle = 1/2 x 360 = 180°
1/4 of the circle = 1/4 x 360 = 90°
Similarly,
1/8 of the circle = 1/8 x 360 = 45°
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.
