To calculate the number needed to increase an average, first determine the current average and the desired average. Then, multiply the current average by the total number of items to find the total sum. Next, calculate the total sum needed for the desired average by multiplying the desired average by the same number of items. Finally, subtract the current total sum from the desired total sum to find the amount needed to increase the average.
Three ways.. Multiply n by itself. Calculate Sum[2i+1,{i,0,n-1}] Calculate Sum[n,{i,1,n}]
To calculate footage for stucco, first determine the total area of the surfaces to be covered by measuring the height and width of each wall. Multiply the height by the width to get the square footage for each wall, then sum these areas to find the total. If there are windows or doors, subtract their areas from the total square footage to get the net area that requires stucco. Finally, consider adding 10% for waste and overage.
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.
auto sum
reciprocal of the sum of the reciprocals.
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
To calculate footage for stucco, first determine the total area of the surfaces to be covered by measuring the height and width of each wall. Multiply the height by the width to get the square footage for each wall, then sum these areas to find the total.

Total welfare is the sum of the consumer and producer surpluses. Consumer Surplus+Producer Surplus=Total Welfare
To calculate the square footage of a room, you multiply the length of the room by the width of the room. This will give you the total area in square feet.
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.
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 ]
