Answer:
the probability of being included in the sample is same for all members of the population of interest. the probability of being selected first for the sample is same as the probability of being selected last
Step-by-step explanation:
A sample is said to be independent random sample if each member of the population has equal chance of being selected.
Answer:
a)148.47
b)148.34
Step-by-step explanation:
Let π(x) be the prime-counting function that gives the number of primes less than or equal to x, for any real number x. For example, π(7) = 4 because there are four prime numbers (2, 3, 5, 7) less than or equal to 7.
We can see that π(7)=π(10) because there are four prime numbers (2,3,5,7) less than or equal to 10.
A good aproximation for π(x) is x / log x, where log x is the natural logarithm of x.
a)The number of primes between 1 and 1030.
1030/log(1030)=148.47
b) The number of primes between 1 and 1029.
1029/log(1029)=148.34
Extra: π(1029)=π(1030) because 1030 is not a prime.
P(not a birthday card) is
(
) because if 14 of the 21 are birthday cards then 21-14=7 are not.
Answer:
X= 2
Step-by-step explanation see X/6 =4/12 all you have to do is multiply the 6 x 2 is 12 and 2x2 is 4 so it would match with the equation
Answer:
Yes!!!
Step-by-step explanation:
Since π is non-terminating non-recurring i.e., an irrational, thus the area will always be rational provided with the circumference is rational.
