7 times the sum of x and s?
=7(x+s)
What is the sum of all numbers from 1 to 25 including in between?
There is a formula to calculate this sum. It is, S = ½n(n + 1) In this question, n = 25 so the sum of the numbers from 1-25 is, ½ x 25 x 26 = 325
Write the sum of x and -7?
x-7
What is the difference between twice the sum of x and y and the sum of twice x and y?
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
What is the sum of all integers not greater than 10000 that are not divisible by 7?
This is easiest to answer by summing all the numbers 1-10000 and subtracting the sum of the multiples of 7 (7, 14, 21, ..., 9996). The sum of a series is: S = (first + last) x number_of_terms / 2 For for 1-10000, the sum is: S1 = (1 + 10000) x 10000 / 2 = 10001 x 5000 = 50005000 For the multiples of 7 the sum is: S2 = (7 + 9996) x 1428 / 2 = 10003 x 714 = 7142142 So the sum of all integers not greater than 10000 that are not divisible by 7 is: S = S1 - S2 = 50005000 - 7142142 = 42,862,858
7 times the sum of x and s?
=7(x+s)
Twice the sum of x and y and The sum of twice x and y?
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
Sum of geometric series using c program?
there are different ways of writing dis program... 1+x+(x*x)+(x*x*x*)+....has a formula for its sum... the sum for a geometric series with a as initial value and x as common ratio is (a*(pow(r,n)-1))/(r-1).... where a=1;r=x.. accept the values of x and n through keyboard remember to take x as a float value!! apply the formula and be careful about the parantheses. happy programming!!!
Formula for s in statistics?
s=sample standard deviation s=square root (Sum(x-(xbar))2 /(n-1) Computing formula (so you don't have to find the mean and the distance from the mean over and over): square root(Sxx /(n-1)) Sxx= Sum(x2) - ((Sum(x))2/n)

What is the sum of x and 10?
the sum equals x+10

If A equals 1 and Z equals 26 what is the sum of the letters in Xmas?
X = 24 M = 13 A = 1 S = 19 Sum = 57
The cube of the sum of x and 4?
the cube of the sum x and 4
What is the formula for finding the sum of angles?
Subtract the number of sides of the polygon by two then multiply it by 180Formula:Interior angle sum = (s-2) x 180 (With s being the number of sides the polygon has.
