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.
Answer:
D) very likely
Step-by-step explanation:
The possible outcomes are 1,2,3,4,5,6
Between means 2,3,4,5
A) certain it is not certain because we could get 1 or 6
B) unlikely we have a 4/6 change of getting our number rolled so it is not unlikely
C) impossible we have a 4/6 change of getting our number rolled so it is not impossible
D) very likely we have a 4/6 change of getting our number rolled so it is better than 50 % we will have one of our numbers rolled
<h2><em>Too many.</em></h2><h2><em></em></h2><h2><em></em></h2><h2><em>In all seriousness... Do 644 / 7. He Sent 92 Texts on Average every day.</em></h2>
Write 2/625 and then multiply the result by 100%: 200%/625 can be re-written as 8% / 25 by dividing both 200 and 625 by 25.
8% / 25 can be thought of as "eight twenty-fifths of 1 percent. (ANSWER)
Using my calculator, I found that 2/625 is 0.0032. Mult. that by 100% results in 0.32. Note that 8/25 = 0.32.
The answer is C. You would use MEAN because it gives you the average although it doesn't always have to be a whole number. Therefore despite that one student performing badly won't affect the rest of the class.
Again hope this helps : )
