Answer:

5 years

Step-by-step explanation:

1. if able's age is x, then his sister's is x-4, and his brother's is 2x

2. if these sum to 32, then we can formulate the equation x+(x-4)+2x=32

3. now solve for x, 4x-4=32, 4x=36, x=9

4. if able's sister is x-4 years old, she is 9-4, or 5 years old

Δ RST is equiangular since all 3 sides are congruent, thus

Each angle in the triangle is 60° , then

7x + 4 = 60 ( subtract 4 from both sides )

7x = 56 ( divide both sides by 7 )

x = 8

Answer:

Domain = {0,-1,-2,-3}

Range = {0,0,0,0}

Step-by-step explanation:

the domain is the set of inputs (x-values)

the range is the set of output (y-values)

The range is all 0 because the coordinates are (0,0) (-1,0) (-2,0) (-3,0)

The evaluation of of the expression -(2⁻⁶)(2³) is - 1 / 8(-1 over 8)

The expression can be evaluated as follows:

-(2⁻⁶)(2³)

The expression can be evaluated using the law of indices,

[tex](x^{a} )^{b} = x^{ab}[/tex] and [tex](x^{-b} )=\frac{1}{x^{b} }[/tex]

Therefore,

-(2⁻⁶)(2³)

2⁻⁶ = 1 / 2⁶ = 1 / 64

2³ = 2 × 2 × 2 = 8

Hence,

-(1 / 64)(8) = -  8 / 64 = - 1 / 8

Answer: (C)

6,2,2,2

Step-by-step explanation:

A mean is an arithmetic average of a set of observations. The set of population data that is the least dispersed from its mean is {6, 2, 2, 2}.

A mean is an arithmetic average of a set of observations. it is given by the formula,

[tex]\rm Mean=\dfrac{\text{Sum of all obervation}}{\text{Number of observation}}[/tex]

To solve the problem we will find the mean of each population set and then add the difference between the mean and each data point.

A.)

[tex]Mean = \dfrac{2+3+2+9}{4} = \dfrac{16}{4} =4[/tex]

Dispersion of each point from the mean,

[tex]\rm |Mean - data\ point|\\|4-2|=2\\|4-3|=1\\|4-2|=2\\|4-9|=5[/tex]

Thus, the dispersion of the population from the means is 10 (2+1+2+5).

B.)

[tex]Mean = \dfrac{4+0+4+0}{4} = \dfrac{8}{4} =2[/tex]

Dispersion of each point from the mean,

[tex]\rm |Mean - data\ point|\\|2-4|=2\\|2-0|=2\\|2-4|=2\\|2-0|=2[/tex]

Thus, the dispersion of the population from the means is 8 (2+2+2+2).

C.)

[tex]Mean = \dfrac{6+2+2+2}{4} = \dfrac{12}{4} =3[/tex]

Dispersion of each point from the mean,

[tex]\rm |Mean - data\ point|\\|3-6|=3\\|3-2|=1\\|3-2|=1\\|3-2|=1[/tex]

Thus, the dispersion of the population from the means is 6 (3+1+1+1).

D.)

[tex]Mean = \dfrac{9+3+5+3}{4} = \dfrac{20}{4} =5[/tex]

Dispersion of each point from the mean,

[tex]\rm |Mean - data\ point|\\|5-9|=4\\|5-3|=2\\|5-5|=0\\|5-3|=2[/tex]

Thus, the dispersion of the population from the means is 8 (4+2+0+2).

Hence, the set of population data that is the least dispersed from its mean is {6, 2, 2, 2}.

Step-by-step explanation:

Answer:

The slope of the line is  [tex]\frac{-5}{3}[/tex] ⇒ D.

Step-by-step explanation:

The rule of the slope of a line is

Use the given figure to find two points on the line

→ From the given figure

∵ The line passes through points (0, 2) and (3, -3)

∴ x1 = 0 and y1 = 2

∴ x2 = 3 and y2 = -3

→ Substitute them in the rule of the slope above to find it

∵ m = [tex]\frac{-3-2}{3-0}=\frac{-5}{3}[/tex]

∴ m = [tex]\frac{-5}{3}[/tex]

∴ The slope of the line is  [tex]\frac{-5}{3}[/tex]
