Answer:
b = infinity
Step-by-step explanation:
1 − 3(3 + 6b) = −6(3b + 1) − 2
1 - 9 - 18b = -18b + 1 -2
1 - 9 = 1 - 2
-8 = -1
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
The answer is standard form. When the equation is set up as Ax + By = C where A and B are coefficients.
