Answer:
The Time in which sum of money double itself is 14 years .
Step-by-step explanation:
Given as :
The principal money = P
The rate of interest = R = 5 % payable half yearly
The Amount = Double of principal
Let The time in which sum become double = t years
I.e A = 2 P
<u>From Compounded method</u>
Amount = principal × 
or, 2 P = P × 
Or, 2 = 
Or, Taking log with base 10 both side
So, 
2 =
or, 0.3010 = 2 t × 1.025
Or, 0.3010 = 2 t × 0.010723
Or, 0.3010 = 0.021446 t
∴ t = 
I.e t = 14.03 years ≈ 14 years
So, The time period = T = 14 years
Hence The Time in which sum of money double itself is 14 years . Answer

2) 49.225
3) 
Step-by-step explanation:
1) To find the expected value of the dice we can use the following equation:
So in our problem the values x will be: 1/1, 1/2, 1/3, 1/4, 1/5 and 1/6 and the probavility for all values is 1/6 so the expected values will be:
2) To find the variance of the expected values we can use the equation:
So for our problem will be:
3) To find the expected value of the dice we can use the following equation:
So in our problem the values x will be: 1, 2, 3, 4, 5 and 6 and the probavility for all values is 1/6 so the expected values will be:
