Answer:
option d) approximately 84%
Explanation:
Data provided in the question:
Mean, m = $92
Standard deviation, s = $13
Now,
we have to calculate percentage of homes will have a monthly utility bill of more than $79 i.e P(X > 79)
also,
P( X > 79) = 1 - P( X < 79)
Z-score for (X = 79 ) = 
Z = 
or
Z = -1
From the standard Z value vs P table, we have
P( Z < -1 ) = 0.1587
Thus,
P( X < 79) = P( Z < -1 ) = 0.1587
therefore,
P(X > 79) = 1 - 0.1587
or
P(X > 79) = 0.8413
or
= 0.8413 × 100%
= 84.13%
Hence,
option d) approximately 84%
Answer:
$245.09
Explanation:
A service contract for a video projection system costs $90 a year. You expect to use the system for three years.
Instead of buying the service contract, the future value of these annual amounts after three years if you earn 5 percent on your savings will be:
PV
Ordinary Annuity
=C×[ ((1−(1+i) ^−n
) / i ]
where
n = number of years = 3
i = interest rate = 5%
Present Value of the annuity = 90 x [ ((1 - (1+0.05)^-3) / 0.05] = $245.09
