The problem is about the application of the sum of arithmetic sequence which has the following formula S=n2(a1+an) where a1 is the first term of the series , an is the nth term and n is the number of terms. Note
# Finding numbers in the array 'x' that are multiples of 3 or 5 n = x[(x % 3 == 0) | (x % 5 == 0)] # Printing the first 1000 elements of the array 'n' print(n[:1000]) # Printing the sum of the numbers in the array 'n' print(n.sum()) Sample Output: [ 3 5 6...
To solve the problem, we need to analyze the sets P, Q, and R, and then check the given relations.1. Define the Sets: - Set \( P \): All integral multiples of 3. This can be represented as: \( P = \{ 3n \mid n \in
不太清楚,How many positive integers less than 1000 are multiples of 5 and are equal to 3 times an even integer?2.since all of these integers are equal to 3 times an even integer,they are all multiples of 3 and 2
The union of sets and is the set of all postitive multiples of 3.The intersection of sets and is the set of all postitive multiples of 6. 结果一 题目 Set is the set of all positive multiples of , and set is the set of all positive multiples of . What is the union and intersecti...
I conclude by suggesting that prints are indeed ontologically unusual insofar as they occupy an intermediate position between pure multiples, of which there can be an unlimited number of tokens, and singular artworks that consist of one physical object....
There are[]= 19 numbers between 1 and 99 that are multiples of 5. If we subtract 19 from199, we get 180 3 digit numbers that are multiples of 5.|A|= 180Another way of looking at it, is that there are 5× 20,5× 21,5×22,5×23×5, and so on to 5 x 199. Therefore ...
