Answer:
12 Years
Step-by-step explanation:
Simple interest is calculated as I = Prt, where P is the principal (amount of money invested), r = rate of interest written as decimal, and t = time
The amount started as P and incresed by Prt, so
P + Prt = 1007.78
616 + (616)(0.053)t = 1007.78
Now you need to solve for t:
Subtract 616 from both sides and simplify:
32.648t = 391.78
Divide both sides by 32.648:
t = 12

Standard deviation = 2.569
The mean = (10 + 15 + 8 + 16 + 14 + 12 + 9 + 12 + 14 + 10) ÷ 10 = 12
x - mean = -2 , 3 , -4 , 4 , 2 , 0 , -3 , 0 , 2 , -2
(x - mean)² = 4 , 9 , 16 , 16 , 4 , 0 , 9 , 0 , 4 , 4
Σ(x - mean)² = 4 + 9 + 16 + 16 + 4 + 0 + 9 + 0 + 4 + 4 = 66
Standard deviation = √(66/10) = 2.569
Answer: 10
The 8 in 5, 829 is representing 800 and the 487 it represents 80,
80 * 10 = 800
