9/12 is number 1. and Number 2 is 1/2 =4/8 and that is 1/2
The formula of the future value of annuity due is
A=p [(1+r/k)^(kn)-1)/(r/k)]×(1+r/k)
A future value of annuity due
P payment 125
R interest rate 0.0375
K compounded monthly 12
N time 8 years
Solve for A
A=125×(((1+0.0375÷12)^(12
×8)−1)÷(0.0375÷12))×(1
+0.0375÷12)
=14,012.75
Answer:
Step-by-step explanation:
For this case we have the following data given:
2.3 3.1 2.8
1.7 0.9 4.0
2.1 1.2 3.6
0.2 2.4 3.2
Since the data are assumedn normally distributed we can find the standard deviation with the following formula:
And we need to find the mean first with the following formula:
And replacing we got:
And then we can calculate the deviation and we got:
Firstly 31*4=124
1*3=3
124-3=121
121/12
<u>Answer</u>
-5 and 5
<u>Explanation</u>
Absolute value generally means the considering the magnitude only but not the sign. -5 and 5 have the same magnitude.
/-5/ = 5
/+5/ = 5
