Confidence interval
The formula for the confidence interval of the true mean is given by:
(1)
The degrees of freedom for this case is given by:
The Confidence level for this case is 0.95 or 95%, and the significance level 
and 
and the critical value is given by 
Replcing into the formula for the confidence interval is given by:
For this case the confidence interval is given by :
Answer:
A = 5x³ + 17x² - 35x - 30
Step-by-step explanation:
the shaded area (A) is calculated as
A = outer area - inner area
= (5x + 3)(x² + 4x - 10) - 3x(2x - 1) ← distribute parenthesis
= 5x³ + 20x² - 50x + 3x² + 12x - 30 - (6x² - 3x)
= 5x³ + 23x² - 38x - 30 - 6x² + 3x ← collect like terms
= 5x³ + 17x² - 35x - 30
Answer:
The perimeter is 92 ft
Step-by-step explanation:
Add all of the sides up
Answer: The answer is the other guys thing
Step-by-step explanation:
Well if the perimeter is 36in, then divide by 6 sides (the prefix hex- means six) to get 6. Don't forget your unit of measurement to be 6in of each side. It would be nice to have the picture though so if you could suply me with that it would help out.
