(11,688.68 , 12,511.32)
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given sample size 'n' = 17
mean of the sample x⁻ = 12,100
Standard deviation of the sample (S) = 800
The 95% confidence interval for the true mean resale value of a 5-year-old car of this model
<u><em>Step(ii):-</em></u>
<u><em>Degrees of freedom ν =n-1 = 17-1 =16</em></u>
<u><em></em></u><u><em></em></u>
The 95% confidence interval for the true mean resale value of a 5-year-old car of this model
(12,100 - 411.32 , 12,100 + 411.32)
(11,688.68 , 12,511.32)
Answer:
The correct expression for the perimeter is
see the explanation
Step-by-step explanation:
The complete question in the attached figure
Let
L ----> the length of rectangle
W ---> the width of rectangle
we know that
The perimeter of rectangle is equal to
In this problem we have
substitute the values
Simplify
so
Michelle didn't multiply the sum of length and width by 2
Answer:
Step-by-step explanation:
=> Since it is an equilateral (Having all angles and all sides equal) triangle, so every angles will be equal to the other.
=> The sum of the measures of interior angles of triangle add up to 180 degrees.
So,
3x + 3x + 3x = 180
9x = 180
Divide both sides by 9
x = 20
