Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
Answer:
1/5, 2/5, 3/5, and 4/5
Step-by-step explanation:
Answer:
The following system of equation has no solution.
Step-by-step explanation:
since both of them are equal to y, set them equal to each other:
3x+1=3x+7
if you subtract both sides by 3x, you get 1=7. That is a contradiction, so this has no solutions.
