Answer:

Step-by-step explanation:

There from ypergemetric distribution

mean number of defective in sample =n×m/N =5×4/10=2

and std deviation =sqrt(mn/N*(1-m/N)*(N-n)/(N-1))

=sqrt(5*4/10*(1-4/10)*(10-5)/(10-1))=0.816

from Tchebysheff's theorem ; 75% values fall within 2 standard deviation from mean

therefore interval in terms of defective

=2-2*0.816 ; 2+2*0.816 =0.367 ; 3.633

interval in terms of  repair costs =20*0.367 ; 20*3.633 =$7.34 ; $ 72.66

lxb=144

16xb=144

b=9

perimeter=2(l+b)

=2(16+9)

=50 cm

Answer: 50cm squared

Step-by-step explanation:

First we need to find the side lengths,

In order to find the area you do,

A = Length x height

we know that the area is 144 and the length is 16.

144=16 x height

144 = 16 x ?

So know we need to find the height, so we do 144/16= 9

so the height 9 cm.

The question is not asking for the height, but the peremeter.

Peremeter = (Length x 2) + (height x 2)

peremeter= 16 x 2 + 9 x 2

peremeter = 32+18

peremeter = 50 cm squared

so the peremeter is 50 cm squared.

As terms help compensate for a quadratic equation. It can indeed be solved in several ways, and the calculation of the equation can be defined as follows:

All quadratic equations can be stated as ax²+bx+c=0, where can not be equal to 0, but can.

Following are solutions to given equation:

[tex]\to[/tex] x² – 5x + 3 = 0

Comparing the value with the standard equation:

[tex]\to[/tex] ax² +bx +c = 0

[tex]\to[/tex] a= 1

[tex]\to[/tex] b=-5

[tex]\to[/tex] c=3

Appling the value into the Shreedhara Acharya's formula:

[tex]\to x = \frac {- b \pm \sqrt{ b^2 - 4ac } } { 2a}\\\\\to x = \frac {- (-5) \pm \sqrt{ (-5)^2 - 4\times 1 \times 3 } } { 2\times 1}\\\\\to x = \frac {+5 \pm \sqrt{ 25 - 12} } { 2}\\\\\to x = \frac {5 \pm \sqrt{ 13} } { 2}\\\\\to x = \frac {5 \pm 3.6} { 2}\\\\\to x = \frac {5 + 3.6 } { 2} \ \ \ \ \ \ OR \ \ \ \ \ \ \ x = \frac {5 - 3.6} { 2}\\\\\to x = \frac {8.6 } { 2} \ \ \ \ \ \ OR \ \ \ \ \ \ \ x = \frac {1.4} { 2}\\\\\to x = 4.3 \ \ \ \ \ \ OR \ \ \ \ \ \ \ x =0.7\\\\[/tex]

Therefore, the value of x is "4.3, 0.7".

Answer:

1486.14

Step-by-step explanation:

When two lines intersect at 90° degrees angle, the lines are perpendicular to each other. Two perpendicular lines, their slope will give a product of -1

i.e. if the first's line slope is 5, then the second line's will be -1 ÷ 5 = -¹/₅

To find the slope of a line, we divide the vertical distance by the horizontal distance.  

We'll use the trial and error method to find the right pairing

Let's start with A(3, 3) and B(12, 6)

Vertical distance =  

Horizontal distance =  

The slope AB = ³/₉ = ¹/₃

We want BC to have a slope -1 ÷ ¹/₃ = -3

Try C(16, -6); check the slope with B(12, 6)

Vertical distance =  

Horizontal distance =  

Slope of BC = -12 ÷ 4 = -3

The slope BC = -3 is the value we want so, tile 1 pair with tile 4

-------------------------------------------------------------------------------------------------------------

Let's do A(-10, 5) and B(12, 16)

Vertical distance = 16 - 5 = 11

Horizontal distance = 12 - -10 = 22

Slope AB = ¹¹/₂₂ = ¹/₂

The perpendicular slope would be -1 ÷ ¹/₂ = -2

Try C(18, 4)  with B(12, 16)

Vertical distance = 16 - 4 = 12

Horizontal distance = 12 - 18 = -6

Slope BC = ¹²/₋₆ = -2

Slope BC and slope AB perpendicular, so tile 3 matches with tile 6

--------------------------------------------------------------------------------------------------------------

Let's try A(12, -14) and B(-16, 21)

Vertical distance = 21 - -14 = 35

Horizontal distance = -16 - 12 = -28

The slope AB = ³⁵/-₂₈ = ⁵/₋₄

We need the perpendicular slope to be -1 ÷ -⁵/₄ = ⁴/₅

Try C(-11, 25)

Vertical distance with B = 25 - 21 = 4

Horizontal distance with B = -11 - -16 = 5

The slope = ⁴/₅

Tile 7 matches tile 8

--------------------------------------------------------------------------------------------------------------

Take A(-12, -19) and B(20, 45)

Vertical distance = 45 - -19 = 64

Horizontal distance = 20 - -12 = 32

Slope AB = ⁶⁴/₃₂ = 2

We need the perpendicular slope to be -1 ÷ 2 = -¹/₂

We have C(6, 52) and checking the slope with B(20, 45)

Vertical distance = 45 - 52 = -7

Horizontal distance = 20 - 6 = 14

The slope is ⁻⁷/₁₄ = -¹/₂

Tile 9 pairs with tile 2

-----------------------------------------------------------------------------------------------------------

Conclusion

Tile 1 ⇒ Tile 4

Tile 3 ⇒ Tile 6

Tile 7 ⇒ Tile 8

Tile 9 ⇒ Tile 2

Tile 5 and Tile 10 do not have pairs

Answer:

Parallel lines = AB and CD

Neither parallel nor perpendicular lines = GH and EF

Step-by-step explanation:

Answer:

3x-4y=18

1xy=18

xy=18 ans

Answer:

X=2/5

Y=-21/5

Step-by-step explanation:

solve your system by substitution.

3x−4y=18;9x−2y=12

Step: Solve3x−4y=18for x:

3x−4y=18

3x−4y+4y=18+4y(Add 4y to both sides)

3x=4y+18

3x/3=4y+18/3

(Divide both sides by 3)

x=4/3y+6

Step: Substitute 4/3y+6 for x in 9x −2y=12:

9(4/3y+6)−2y=12

10y+54=12(Simplify both sides of the equation)

10y+54+−54=12+−54(Add -54 to both sides)

10y=−42

10y/10=-42/10 .   (Divide both sides by 10)

y=-21/5

Step: Substitute

21/5 fory in x= 4/3y+6

x= 4/3y (-21/5) +6

  X=2/5 (Simplify both sides of the equation)

           Answer:

          X=2/5

          Y=-21/5

Answer:

Point C

Step-by-step explanation:

Each of the lines are counted by 5 and if counting carefully, C would be 0.75, or, 3/4

Point C on the number line below represents a value of 0.75.

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

To find point on the number line which represents a value of 0.75..

Now, We get;

Point A = 0.3

Point B = 0.55

Point C = 0.75

Thus, Point C on the number line below represents a value of 0.75.

Answer:

1.04167

Step-by-step explanation:

Z -score formula is given as

z = (x-μ)/σ, where

x is the raw score = 74

μ is the population mean = 69

σ is the population standard deviation = 4.8

Z score = x - μ/ σ

= 74 - 69/4.8

= 1.04167

The z score for a person is given as 1.04167

Answer:

x = -5

Step-by-step explanation:

-3X + 25 =40 : Rearrange the expression

-3X = 40 - 25 : Separate the constants and variables

-3X=15 : Subtract the numbers

-3X/-3 = 15/-3 : Divide both sides by -3
