Simplify each expression

Simora [160]

$2x-2y-6x-3-2y+6=(2x-6x)+(-2y-2y)+(-3+6)\\\\=-4x-4y+3\\\\3x+4y+2y-4+5y-10=(3x)+(4y+2y+5y)+(-4-10)\\\\=3x+11y-14\\\\3x-6y-6+2x+6y+2=(3x+2x)+(-6y+6y)+(-6+2)\\\\=5x-4\\\\8x+2y+3x-9y+3x^2-2y=(3x^2)+(8x+3x)+(2y-9y-2y)\\\\=3x^2+11x-9y$

The smaller the standard deviation, _______________________. Select one: a. the less variability it has b. the more variability

algol13

Answer:

a. the less variability it has

Step-by-step explanation:

The standard deviation is a measure of the amount of variation or dispersion of a set of values.

When your standard deviation is big your data is more dispersed.

When your standar deviation is small your mean is a representative index of your data, and there is less variability.

If there was no dispersion of the data (if all your data be the same) then the standard deviation will be 0.
