The coefficient tells you how many molecules of that substance there is. The subscript tells you what the substance it. It tells you the the amount of each element there are in the molecule.

The coefficient in a chemical formula represents the amount of each chemical present. The amount of a substance is measured in moles.

A coefficient is a number used to multiply a variable. Example: 6z means 6 times z, and “z” is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. Example: In ax2 + bx + c, “x” is a variable, and “a” and “b” are coefficients.

The coefficient of x² is 1 in 2+x²+x as there is only term with x² in the equation . Hope you understood.

There is no x² term , so it’s coefficient is 0 .

Coefficient of x2=−1.

The coefficient of y in −3xy is −3x.

A coefficient is any of the factors of a term relative to a given factor of the term. In the term -5x2y, the coefficient of “y” is -5×2. In the term -5x2y, the coefficient of “x2” is -5y. o2z1qpv and 5 more users found this answer helpful. Thanks 3.

coefficient of xyz2 in the term 5xyz2 is 5. coefficient of zy in the term –3zy is –3.

So, the coefficient of (5−y)2 is −10.

Answer. Therefore, coefficient of y is -10.

Pearson’s coefficient of skewness (second method) is calculated by multiplying the difference between the mean and median, multiplied by three. The result is divided by the standard deviation. You can use the Excel functions AVERAGE, MEDIAN and STDEV. P to get a value for this measure.

The combinations formula is: nCr = n! / ((n – r)! r!) n = the number of items. r = how many items are taken at a time.

In Maths, nPr and nCr are the probability functions that represent permutations and combinations. The formula to find nPr and nCr is: nPr = n!/(n-r)!

In mathematics, combination or nCr, is the method of selection of ‘r’ objects from a set of ‘n’ objects where the order of selection does not matter.

permutation

You can work permutations and combinations on the TI-84 Plus calculator. A permutation, denoted by nPr, answers the question: “From a set of n different items, how many ways can you select and order (arrange) r of these items?” One thing to keep in mind is that order is important when working with permutations.
