Answer:

The domain is {(-2,1),(-1,2),(-3,\dfrac{5}{3})}

Step-by-step explanation:

Given that,

The function is

f(x,y)=(-2x,-3y+1)

The coordinates of range are,

range=(4,-2), (2,-5), (-6,4)}

The domain is,

Domain={(x_{1},y_{1}),(x_{2},y_{2}),(x_{3},y_{3})}

We need to find the value of x₁ and y₁

Using given function

f(x.y)=(-2x,-3y+1)

f(x_{1},y_{1})=(4,-2,)

(-2x_{1},-3y_{1}+1)=(4,-2)

On equating value of x

-2x_{1}=4

x_{1}=-2

On equating value of y

-3y_{1}+1=-2

-3y_{1}=-2-1

y_{1}=\dfrac{-2-1}{-3}

y_{1}=1

We need to find the value of x₂ and y₂

Using given function

f(x_{2},y_{2})=(2,-5,)

(-2x_{2},-3y_{2}+1)=(2,-5)

On equating value of x

-2x_{2}=2

x_{2}=-1

On equating value of y

-3y_{2}+1=-5

-3y_{2}=-5-1

y_{2}=\dfrac{-5-1}{-3}

y_{2}=2

We need to find the value of x₃ and y₃

Using given function

f(x_{3},y_{3})=(-6,4,)

(-2x_{3},-3y_{3}+1)=(-6,4)

On equating value of x

-2x_{3}=-6

x_{3}=-3

On equating value of y

-3y_{3}+1=-4

-3y_{3}=-4-1

y_{3}=\dfrac{-4-1}{-3}

y_{3}=\dfrac{5}{3}

We need to find the domain

Using domain

Domain={(-2,1),(-1,2),(-3,\dfrac{5}{3})}

Hence, The domain is {(-2,1),(-1,2),(-3,\dfrac{5}{3})}

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.

Mhanifa can you please help with this??? Look at the picture attached. Thanks!
EastWind [94]

Answer:

<u>Properties of a rhombus used to solve the following </u>

  • <em>Opposite angles are congruent</em>
  • <em>Diagonals are angle bisectors</em>
  • <em>Diagonals are perpendicular to each other</em>
  • <em>Adjacent angles are supplementary</em>

(30)

  • ∠2 = ∠3 = ∠5 = 27°
  • ∠1 = ∠4 = 180° - (2*27°) = 126°

(31)

  • ∠4 = 70°
  • ∠1 = ∠2 = ∠3 = ∠5 = 1/2(180° - 70°) = 1/2(110°) = 55°

(32)

  • ∠1 = ∠2 = ∠5 = 90° - 26° = 64°
  • ∠3 = 26°
  • ∠4 = 90°
