Answer:
b. 0.5
Step-by-step explanation:
knowing that a prime number is an integer with exactly two divisors and a composite number is an integer with more than two divisors, we have that if q is a composite number greater than 2 these can be 4, 6, 8, .. But how the smallest of them should be is 4, and p is a prime number can be 2,3,5,7,....
but is the smallest prime number less than 10 then p=2, also p/q=2/4 = 0.5
B is the correct answer 'friendship'
Answer:
51
Step-by-step explanation:
Given

Where will the mean approach if sample size increase
Using central limit theorem, we have:


This means that; as n approaches infinity, the mean is almost expected to the
i.e. expected to remain unchanged.
Hence, the mean value will approach 51.
The answer would be 150
To solve this do 50x30 and you would get 150
