Answer:
Its the first option
40,000,000(0.9)x.
Step-by-step explanation:
90% recognise her each year so after 1 year so the number (N) is:
N = 40,000,000(0.90)^1 = 36,000,000 recognise her after 1 year.
N = 40,000,000(0.90)^2 = 32,400,000 recognise her after 2 yeas
- and so on.
After x years:
N = 40,000,000(0.90)^x.
Note the x is a power and is best written as ^x.
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The population size is N = 31
The sample size n = 4
Generally the number of way by which the n can be selected from N is mathematically represented as
=> 
=> 
=> 
=> 
The number of ways of selecting a particular sample size is is 
Therefore the probability of each simple random sample in this case is mathematically evaluated as
