Answer:
- $17,500 at 8%
- $17,500 at 14%
Step-by-step explanation:
The fraction that needs to be invested at the higher rate is ...
(11% - 8%)/(14% -8%) = 3%/6% = 1/2
Half the money should be invested at each of the rates:
$17,500 for 8% return
$17,500 for 14% return.
_____
If you let x represent the amount at the higher rate, then the total return is ...
14%x + 8%(35000 -x) = 11%(35000)
(14% -8%)x = (11% -8%)(35000) . . . . subtract 8%·35000
x = (11% -8%)/(14% -8%)×35000 . . . . divide by the coefficient of x
Note that this formula is exactly the one we started with, above.
Answer:
0.0105
Step-by-step explanation:
given that 30% of all houses need a paint job. Also, 15% of all houses need both a paint job and a new roof. Further, 7% of all houses that need a new roof also need new windows.
If total houses are 100, then 30 require a paint along. 15 require both paint and new roof.
Out of 15 houses which require new roof 7% need new windows
i.e. no of houses which need new windows = ![15*7%\\=1.05](https://tex.z-dn.net/?f=15%2A7%25%5C%5C%3D1.05)
If there are total 100 houses, 1.05 houses require a new window
So probability that a randomly selectede house needs a new window
= 0.0105
Step-by-step explanation:
![\frac{9.2 \times {10}^{ - 8} }{2.3 \times {10}^{3} } \\ = 4.0 \times {10}^{ - 11}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9.2%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%208%7D%20%7D%7B2.3%20%5Ctimes%20%20%7B10%7D%5E%7B3%7D%20%7D%20%20%5C%5C%20%20%3D%204.0%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%2011%7D%20)
