Web1. The reciprocal of a number is this fraction flipped upside down. In other words, the reciprocal has the original fraction's bottom number—or denominator —on top and the top number—or numerator —on the bottom. So the reciprocal of 6 is 1/6 because 6 = 6/1 and 1/6 is the inverse of 6/1. Below, you can see more reciprocals. WebNote that this proof answers all three questions we posed. It’s the variances that add. Variances add for the sum and for the difference of the random variables because the plus-or-minus terms dropped out along the way. And independence was why part of the expression vanished, leaving us with the sum of the variances.

WebA polynomial is an expression that consists of a sum of terms containing integer powers of x x, like 3x^2-6x-1 3x2 −6x −1. A rational expression is simply a quotient of two polynomials. Or in other words, it is a fraction whose numerator and denominator are polynomials. These are examples of rational expressions: \dfrac {1} {x} x1 WebThese are polynomials: 3x x − 2 −6y2 − ( 7 9 )x 3xyz + 3xy2z − 0.1xz − 200y + 0.5 512v5 + 99w5 5 (Yes, "5" is a polynomial, one term is allowed, and it can be just a constant!) These are not polynomials 3xy-2 is not, because the exponent is "-2" (exponents can only be 0,1,2,...) 2/ (x+2) is not, because dividing by a variable is not allowed floor hatch key re7
