Three ways.. Multiply n by itself. Calculate Sum[2i+1,{i,0,n-1}] Calculate Sum[n,{i,1,n}]
You square each number and multiply that by the frequency with which that number appears. You then sum together these results.
A box has six square surface; the total surface area of each box is the sum of the surfaces of the six squares. If you have 4 boxes: * If all are the same size, calculate the above, then multiply by 4. * If they are of different sizes, calculate each box separately, then add everything up.
The sum of a [single] square equals the square.
How can anyone have doubt in this question. Square of 3= 9 Square of 5= 25 Square of 7= 49 Total is = 83

All internal angles of a quadrilateral like a square sum to 360 degrees.
1/2*(sum of parallel bases)*height = area
Total welfare is the sum of the consumer and producer surpluses. Consumer Surplus+Producer Surplus=Total Welfare
In general, you divide up the polygon into triangles, calculate the areas of the triangles and then sum these.
If you have a data set, simply take the square root of the sum of the squares of the data points. Let's say you have three numbers a, b, and c. RSS = SQRT(a2 + b2 + c2).
You square each number and multiply that by the frequency with which that number appears. You then sum together these results.

To calculate the magnitude of the resultant vector, you can use the Pythagorean theorem. Square the x-component of the vector, square the y-component of the vector, and sum them together. Finally, take the square root of the resulting sum. The formula is: |R| = sqrt((Rx^2) + (Ry^2)).
