How do you find the sum of the first 100 integers?

The sum of the numbers 1-100 would be equal to the number of pairs (50) multiplied by the sum of each pair (101), or 50 x 101 = 5,050. Karl was able to use what he knew about numbers to solve what seemed like a complicated assignment in a short amount of time.

What is the average of positive integers from 1 to 100?

Sum of AP is given by, {n * (a + l) /2} [Where a = first term, n = number of terms, l = last term.] = 100 * (1 +100)/2 = 50 * 101. Required Average = (50 *101)/100 = 50.5.

What is the average of 1 100?

Thus, 50.5 is an average of positive integers 1 and 100.

What is the mean of 1 to 10?

step 2 Find the sum of numbers from 1 to 10. Thus, 5.5 is an average of numbers from 1 to 10.

What is the average of 1?

1 Answer. Average of one number is always the number itself, as average is sum of the numbers divided by their count. As there is only one number this calculation is always the number itself.

What are the median numbers?

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). Example: The median of 4, 1, and 7 is 4 because when the numbers are put in order (1 , 4, 7) , the number 4 is in the middle.

How do you find the median class for grouped data?

The formula for median in a grouped data is median=l+(n2−cff)×h, where l represent the lower limit of the median class, n represents the total sum of all frequencies, cf represent the cumulative frequency before the median class, f represent the frequency of the median class and h represents the class width.

How do you find the median in statistics class 11?

Firstly, arrange the terms in ascending or descending order and then find the number of terms n. (a) If n is odd, then (n + 1 / 2)th term is the median.

How do you find the mean of a Class 11?

There are two steps to find the arithmetic mean in statistics: sum up all the numbers given in a set. and then divide it by the total number of items in your set.

What is the median of the two middle numbers are the same?

If there is an even number of numbers add the two middles and divide by 2. The result will be the median.
