Answer:
31877 people with live in the town in 2016 if the population increases at a rate of 6% every 2 years
Step-by-step explanation:
The formula used will be
A(t) = P(1+r)^t
A(t) = Future value
P = population
r = rate
t = time
P= 20,000
r =6% or 0.06
t = 16
Since population is increased every 2 years, so t = 16/2 = 8
Putting value:
A(16) = 20,000(1+0.06)^8
A(16)= 20,000(1.06)^8
A(16) = 31876.9 ≈ 31877
So, 31877 people with live in the town in 2016 if the population increases at a rate of 6% every 2 years
Answer:
A.) The probability that the missile is not detected by any of n sets = (1-0.9)^n = 0.1^n.
Where it's opposite will be that the missile is detected by atleast 1 of the sets. Which will be equals to 1-(0.1)^n.
B.) 0.999= 1-(0.1)^n
Here n=3
For, 0.999999=1-(0.1)^n
n=6.
C.) If n=5
5C4*(0.9)^4*(0.1)^1= 0.32805
