How do calculate the number needed to increase an average?
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.
How can you find the nth square number?
Three ways.. Multiply n by itself. Calculate Sum[2i+1,{i,0,n-1}] Calculate Sum[n,{i,1,n}]
How to calculate footage for stucco?
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.
How do you find total sum of squares?
You square each number and multiply that by the frequency with which that number appears. You then sum together these results.
How do you work out meter square on 4 boxes?
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.
Which toolbar button can you use to calculate your total expenses?

How do you calculate the square footage of a room?
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.
How do you get the square inches of a polygon?
In general, you divide up the polygon into triangles, calculate the areas of the triangles and then sum these.
How do you calculate root sum squared?
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).
How do you find total sum of squares?
You square each number and multiply that by the frequency with which that number appears. You then sum together these results.
