I believe the greatest common factor would be 1 because there are no other multiples that are the same. 1•21=21, and1•40=40
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.
This one is for number 26
That's the simplest form of 15/35. You can use
3/7 to get other equivalent fractions by multiplying the numerator and denominator by the same number. Other examples are
9/21, 6/14, and 12/28.
Hope this helps!
