<span>Half-span is half of span. Pitch of the roof is calculated as rise/(span/2). In this case, rise is 8 feet and span is 30 feet. So, the pitch can be calculated as 8/(30/2) or 8/15. Pitch is normally represented as the number of inches of rise per foot. So, to reduce 8/15 to match a foot, we multiply it by 12. So, (8/15) * 12 gives us 6.4 inches of rise per foot.</span>

Answer:


Step-by-step explanation:
For this case we have the following data:
Days to Maturity Dollar Value $ Millions)
20 20
12 30
7 10
5 15
6 10
For this case the definition of weigthed mean is given by:

Where
represent the weight of each value and
represent the observations (Days to maturity)
Our interest is the number of days so then our weighting variable would be the dollar Value, so then we can find the weighted mean like this:


Answer:
(x - 3) is a factor of the given function
Step-by-step explanation:
Given function:

If (x - 3) is a factor of the given function then 
Substitute x = 3 into the function and solve:



Therefore, as
then (x - 3) is a factor of the given function.
