d
Step-by-step explanation:
Answer:
9.5
Step-by-step explanation:
Find the sample variance for the data 9,12,9,14,6. Round the answer to one decimal place. Sample variance.
Step 1
We find the Mean of the numbers
Mean = Sum of terms/ Number of terms
Mean = 9+12+9+14+6/5
= 50/5
= 10
Step 2
We find the sample variance
Formula =
(x - Mean)²/n - 1
n = 5
= (9 - 10)²+(12 -10)²+(9- 10)²+(14-10)²+(6-10)²/5 - 1
= 1+ 4+ 1+ 16+16/5 - 1
= 38/5 - 1
= 38/4
= 9.5
Therefore, Sample variance = 9.5
For this case we must find the domain of the following function:
![f (x) = \frac {x + 5} {x-2}](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%20%5Cfrac%20%7Bx%20%2B%205%7D%20%7Bx-2%7D)
By definition, the domain of a function is given by all the values for which the function is defined. The given function is not defined when the denominator is zero, that is:
![x-2 = 0\\x = 2](https://tex.z-dn.net/?f=x-2%20%3D%200%5C%5Cx%20%3D%202)
Thus, the domain of the function is given by real numbers except 2.
Answer:
All real numbers except 2
