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: 9 a^8 b^12 c^16
Step-by-step explanation:
4√81/16a^8b^12c^16
= 4 x 9/4a^8b^12c^16
= 9a^8b^12c^16
Answer:
I think it's 1/6 for the cube and 1/2 for the coin. so it would be 2/8 which would be 1/4 simplified, so in decimal form the probability is .25
