Answer:
Mean: 76.42
Population: 7
Mean absolute deviation: 13.06
Step-by-step explanation:
Annuity formula is given by:
FV=P[(1+r)^n-1]/r
FV=future value
r=rate
n=time
P=principle
Plugging the value from the question we obtain:
FV=10000[(1+0.07)^6-1]/0.07
FV=71,532.91
Thus the current value of the annuity is given by:
A=p(1+r)^n
plugging in the values we obtain and solving for p we get:
71532.91=p(1+0.07)^6
p=71532.91/(1.07)^6
p=$47665.40
Hence the answer:
B] $47665
126 1/4 - 78 2/3 =
505/4 - 236/3 =
1515/12 - 944/12 =
571/12 =
47 7/12 <==
X = 20
If you multiply both sides by 5 to get rid of the fraction ( x - 60 = -40 ) the answer would become clear.
To convert to percent from fraction you divide the numerator by the denominator. from percent to decimal you move two decimal places to the left.
