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.
How can anyone have doubt in this question. Square of 3= 9 Square of 5= 25 Square of 7= 49 Total is = 83
The sum of a [single] square equals the square.
Calculate one third of the sum of 23 and the square of 5
reciprocal of the sum of the reciprocals.
auto sum
Three ways.. Multiply n by itself. Calculate Sum[2i+1,{i,0,n-1}] Calculate Sum[n,{i,1,n}]
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.
You square each number and multiply that by the frequency with which that number appears. You then sum together these results.
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).
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.
Magnitude of the resultant vector = Square root of[ (sum of x-components of all component vectors)2 plus(sum of y-components of all component vectors)2plus (sum of z-components of all component vectors)2 ]
