Answer:

D. 2.7

Step-by-step explanation:

Given

[tex]Mean = 8.0[/tex]

[tex]n = 20[/tex]

[tex]Range = 2.5\ to\ 12.0[/tex]

Required

Estimate the standard deviation

Since, the given data has incomplete parameters, we can apply the range rule to estimate the standard deviation;

This is done as follows;

[tex]S.D = \frac{1}{4}(Max - Min)[/tex]

In this case:

[tex]Max = 12.0[/tex]

[tex]Min = 2.5[/tex]

So:

[tex]S.D = \frac{1}{4}(Max - Min)[/tex]

[tex]S.D = \frac{1}{4}(12.0 - 2.5)[/tex]

[tex]S.D = \frac{1}{4}(9.5)[/tex]

[tex]S.D = 2.375[/tex]

From the list of given option, the closest to 2.375 is 2.7;

Hence, the best estimate is 2.7

The correct option is D. 2.7

Given that,

The standard deviation should be

[tex]= \frac{1}{4} (12 - 2.5)\\\\ = \frac{1}{4} (9.5)[/tex]

= 2.375

= 2.7

Answer:

n^2/4

Step-by-step explanation:

If n is the number, squared is n^2

Quotient if this number and four is

n^2/4

The quotient of a number squared and four will be n² / 4.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Division means the separation of something into different parts, sharing of something among different people, places, etc.

The square of a number is the multiplication of that number with itself.

Let the number be n.

Then the square of the number n will be given as,

⇒ n²

The quotient of a number squared and four will be given as,

⇒ n² / 4

Thus, the quotient of a number squared and four will be n² / 4.

Answer:

[tex] x = \frac{6 \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)} [/tex]

Step-by-step explanation:

Given the equation, [tex] 3x^2 - 6x + 8 = 0 [/tex], the quadratic formula for solving this equation is given as:

[tex] x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

Where,

a = 3

b = -6

c = 8

Plug in the above values into the quadratic formula.

[tex] x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)} [/tex]

[tex] x = \frac{6 \pm \sqrt{(-6)^2 - 4(3)(8)}}{2(3)} [/tex]

Answer:

LM = 28 units

Step-by-step explanation:

Length of segment KL = (4x + 7) units

Length of segment LM = (5x - 12) units

Length of LM = 67 units

Since length of KM = length of KL + length of LM

By substituting the given values in the expression,

67 = (4x + 7) + (5x - 12)

67 = (4x + 5x) + (7 - 12)

67 = 9x - 5

9x = 67 + 5

x = [tex]\frac{72}{9}[/tex]

x = 8

Therefore,

LM = (5x - 12)

     = (5×8) - 12

     = 40 - 12

     = 28

Length of segment KM is 28 units.

Answer:

  divide by 5: x = 13/5 = 2.6

Step-by-step explanation:

Make use of the properties of the multiplicative inverse and the multiplication identity element. Multiplying both sides of the equation by the multiplicative inverse of the coefficient of x makes the result be 1x on the left side.

  (1/5)(5x) = (1/5)(13)

  1x = 13/5

The multiplicative identity element (1) does not change the value of what it multiplies, so this simplifies to ...

  x = 13/5

_____

Effectively, we divide (both sides) by 5.

Answer:

Step-by-step explanation:

2x + 5y = 7 ......... Equation 1

x = 2 - 4y .......... Equation 2

Substitute x that's equation 2 into equation 1 and solve for y

That's

2( 2 - 4y ) + 5y = 7

4 - 8y + 5y = 7

- 3y + 4 = 7

- 3y = 7 - 4

- 3y = 3

Divide both sides by - 3

y = - 1

Substitute the value of y into equation 1

That's

x = 2 - 4(-1)

x = 2 + 4

x = 6

Therefore the solutions are

Answer:

(2,3) and (7,10)

Step-by-step explanation:

Use the slope 5/7 to get to a new point by moving up 5 units and moving to the right 7 units.

If the coordinate point is (x, y) then the coordinate of the other point will be (x + 5, y + 7).

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

The slope is the ratio of the rise or fall and run.

The slope is 5/7. The rise is 5 and the run is 7.

If the coordinate point is (x, y) then the coordinate of the other point will be (x + 5, y + 7).

20 cent per inch

Answer:

plz show the pic so I can understand

Answer:

Step-by-step explanation:

Given the following complex numbers, we are to expressed them in the form of a+bi where a is the real part and b is the imaginary part of the complex number.

1) (2-6i)+(4+2i)

open the parenthesis

= 2-6i+4+2i

collect like terms

= 2+4-6i+2i

= 6-4i

2)  (6+5i)(9-2i)

= 6(9)-6(2i)+9(5i)-5i(2i)

= 54-12i+45i-10i²

= 54+33i-10i²

In complex number i² = -1

= 54+33i-10(-1)

= 54+33i+10

= 54+10+33i

= 64+33i

3) For the complex number 2/(3-9i), we will rationalize by multiplying by the conjugate of the denominator i.e 3+9i

= 2/3-9i*3+9i/3+9i

=2(3+9i)/(3-9i)(3+9i)

= 6+18i/9-27i+27i-81i²

= 6+18i/9-81(-1)

= 6+18i/9+81

= 6+18i/90

= 6/90 + 18i/90

= 1/15+1/5 i

4) For (3 − 5i)(7 − 2i)

open the parenthesis

= 3(7)-3(2i)-7(5i)-5i(-2i)

= 21-6i-35i+10i²

= 21-6i-35i+10(-1)

= 21-41i-10

= 11-41i

  Simplified form of the given expressions will be,

1). 6 - 4i

2). 64 + 33i

3). [tex]\frac{1}{15}+\frac{1}{5}i[/tex]

4). [tex]\frac{31}{53}-\frac{31}{53}i[/tex]

1). In a complex number (a + bi),

    a = Real part of the complex number

   bi = Imaginary part

     Expression given in the question → (2 - 6i) + (4 + 2i)

Rule to solve the given expression,

"Add real part and imaginary part of two complex numbers separately"

(2 - 6i) + (4 + 2i) = (2 + 4) + (-6i + 2i)

                         = 6 + (-4i)

                         = 6 - 4i

  Therefore, simplified form of the given expression will be (6 - 4i).

2). Given expression → (6 + 5i)(9 - 2i)

Rule to solve the expression → i² = -1

(6 + 5i)(9 - 2i) = 6(9 - 2i) + 5i(9 - 2i)

                       = 54 - 12i + 45i - 10i²

                       = 54 - 12i + 45i + 10 [Since, i² = -1]

                       = (54 + 10) + (45i - 12i)

                       = 64 + 33i

     Therefore, simplified form of the given expression will be (64 + 33i).

3). Given expression → [tex]\frac{2}{3-9i}[/tex]

Multiply numerator and denominator with the conjugate of (3 - 9i) to convert the expression into (a + bi).

[tex]\frac{2}{3-9i}= \frac{2(3+9i)}{(3-9i)(3+9i)}[/tex]

       [tex]=\frac{2(3+9i)}{3^2-(9i)^2}[/tex]

       [tex]=\frac{6+18i}{9-81(-1)}[/tex]

       [tex]=\frac{6+18i}{9+81}[/tex]

       [tex]=\frac{6+18i}{90}[/tex]

       [tex]=\frac{6(1+3i)}{90}[/tex]

       [tex]=\frac{1}{15}+\frac{1}{5}i[/tex]

    Therefore, simplified form of the given expression will be [tex]\frac{1}{15}+\frac{1}{5}i[/tex]

4). Given expression → [tex]\frac{(3-5i)}{(7-2i)}[/tex]

Multiply numerator and denominator with the conjugate of the denominator.

[tex]\frac{(3-5i)}{(7-2i)}=\frac{(3-5i)(7+2i)}{(7-2i)(7+2i)}[/tex]

         [tex]=\frac{3(7+2i)-5i(7+2i)}{7^2-(2i)^2}[/tex]

         [tex]=\frac{21+4i-35i-10i^2}{49-4(-1)}[/tex]

         [tex]=\frac{21-31i+10}{53}[/tex]

         [tex]=\frac{31-31i}{53}[/tex]

         [tex]=\frac{31}{53}-\frac{31}{53}i[/tex]

  Therefore, simplified form of the given expression will be [tex]\frac{31}{53}-\frac{31}{53}i[/tex].

Answer:

Line UM.

Step-by-step explanation: you can name a line by naming at least two points on it.

Line l can be called line UM, line LM, and line UL because line l is contained in plane S.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

m is the ratio of the line,

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases.

It is given that:

A plane S contains a line l.

It is possible to give a name for line l in different ways.

The line l can be called:

Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.
