Answer:
2
Step-by-step explanation:
Evaluate p + 4 - 1 - (r + 4) where p = 4 and r = 1:
p + 4 - 1 - (r + 4) = 4 + 4 - 1 - (4 + 1)
4 + 1 = 5:
4 + 4 - 1 - 5
4 + 4 - 1 - 5 = (4 + 4) - (1 + 5):
(4 + 4) - (1 + 5)
4 + 4 = 8:
8 - (1 + 5)
1 + 5 = 6:
8 - 6
8 - 6 = 2:
Answer: 2
Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
Given:
Amount after three years = $10000
Rate of interest = 8.2 percent compounded monthly = 0.082
Time = 3 years
To find:
The principal value.
Solution:
Formula for amount is
where, P is principal, r is rate of interest, n is the number of times interest compounded in an year, t is number of years.
Substitute A=10000, r=0.082, n=12 and t=3 in the above formula.
Divide both sides by 1.27783.
Therefore, today she have to deposit $7825.767.
