Answer: A(x) = 15 ft + 2x
EXPLANATION
Given,
The dimension of the rectangular garden is 20 ft by 15 ft.
Dimension of a rectangle is written as Length by Width
This implies that,
Length of the garden = 20 ft
Width of the garden = 15 ft
The garden has a walk around it of width x.
The combined width of the garden = Width of garden + 2x
[we are adding twice the width of the walk because it is
around the garden (this means it will add to the width of the garden on both the left and right sides)]
Combined width of the garden, A(x) = Width of garden + 2x
Since width of the garden = 15 ft
A(x) = 15 ft + 2x
Answer:
Now we can find the second central moment with this formula:
And replacing we got:
And the variance is given by:
And replacing we got:
And finally the deviation would be:
Step-by-step explanation:
We can define the random variable of interest X as the return from a stock and we know the following conditions:
represent the result if the economy improves
represent the result if we have a recession
We want to find the standard deviation for the returns on the stock. We need to begin finding the mean with this formula:
And replacing the data given we got:
Now we can find the second central moment with this formula:
And replacing we got:
And the variance is given by:
And replacing we got:
And finally the deviation would be:
Answer: False.
