Answer:

Step-by-step explanation:

i multiplied the S values by the scale factor to get the S dash

The coordinates of the point S' after dilation is S' ( 4 , 2 )

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

Given data ,

Let the triangle be represented as ΔSTU

Now , the coordinates of the triangle are

S ( 2 , 1 ) , T ( 4 , 5 ) and U ( 4 , 1 )

Now , the dilation scale factor is k = 2

So , the coordinates of the triangle after the dilation is

S' ( 4 , 2 ) , T' ( 8 , 10 ) and U' ( 8 , 2 )

Hence , the coordinate of S' is S' ( 4 , 2 )

Step-by-step explanation:

Answer:

m⊥ = –½

Step-by-step explanation:

First, put the given equation in slope-intercept form:

2x – y = –6

–y = –2x – 6

y = 2x + 6

The slope of the line perpendicular to the line given will be the negative reciprocal of the given line's slope, so:

If m = 2, then m⊥ = its negative reciprocal:

m · –1

2 · –1

–2  →  –½

So, the negative reciprocal of 2 is –½.

Answer:

The answer is D, h=3Vπr2. The height of the cone is 6 cm

Step-by-step explanation:

The Height of the Cone is 6 cm.

The shape's volume is equal to the product of its area and height. = Height x Base Area = Volume.

The formula for the volume of a cone is V=1/3hπr².

Given:

Volume of Cone= 1/3 πr²h

where r is the radius and h is the height.

Now, if V= 32π cm³ and r= 4 cm

Then, Volume of Cone = 1/3 πr²h

                               32π = 1/3 π(4)²h

                               32 = 1/3  (4)²h      

                                32= 1/3 (16)h

                                h/3 = 2

                               h= 6cm

Hence, the height is 6 cm.

Answer:

The new coordinates of the triangle J'K'L' are J'(0, -3), K'(3, -4), and J'(6, 0)

Step-by-step explanation:

The given coordinates of the triangle JKL are;

J(3, 0), K(4, 3), L(6, 0)

The rotation of the point of a preimage (x, y) by 90° clockwise gives the point of the image after rotation as (y, -x)

Therefore;

The rotation of point J(3, 0) by 90° clockwise gives J'(0, -3)

The rotation of point K(4, 3) by 90° clockwise gives K'(3, -4)

The rotation of point L(6, 0) by 90° clockwise gives J'(6, 0)

The new coordinates of the triangle J'K'L' are J'(0, -3), K'(3, -4), and J'(6, 0)

Step-by-step explanation:

The question says that there are 70 people in a group. Its then asks who many people would be in 2, 4, and 9 groups. Just muliply to get each answer and put it in the graph.

Answer:

(a) The system of equations is:

2r + b = 8.40

3r + b = 9.35

(b) The graph is attached down

(c) By using the graph

The cost of the refill is $0.95

The cost of the egg breakfast is $6.5

Step-by-step explanation:

Let r is the amount charged for a refill and b for  the amount charged for the egg breakfast

∵ r is the amount charged for a refill

∵ b is the amount charged for the egg breakfast

∵ You ordered 2 drink refills and the egg  breakfast, for a total of $8.40

∴ 2r + b = 8.40 ⇒ (1)

∵ Your friend ordered 3 refills and the egg breakfast for $9.35

∴ 3r + b = 9.35 ⇒ (2)

(a) The system of equations is:

2r + b = 8.40

3r + b = 9.35

(b) The graph is attached down

From the graph

The red line represents equation (1)

The blue line represents equation (2)

The two lines intersected at point (0.95, 6.5)

(c) By using the graph

The cost of the refill is $0.95

The cost of the egg breakfast is $6.5

Answer:

2. -1.5, 0

3. -6, 9

5. 3, -9

Step-by-step explanation:

Given parameters:

    Slope  = -2

    y - intercept  = -3

Unknown:

The point that lies on the line  = ?

Solution:

 To do the equation of the line,

        y  = mx + c

y and x are the coordinates

m is the slope

c is the y -intercept

Input the parameters:

            y= -2x -3

The points that lie on the line will conform with the equation:

          y + 2x  = -3

1. -2, 0

   y = 0 and x = -2

       0 + (-2)2 = -4

2. -1.5, 0

  y = 0 and x = -1.5

      0 + 2(-1.5) = -3

3. -6, 9

   y = 9, x  = -6

    9 + 2(-6) = 9 - 12 = -3

4. 2, -3

    y = -3 and x = 2

    -3 + 2(2) = -3 + 4 = 1

5. 3, -9

    y = -9, x  = 3

      -9 + 2(3) = -9 + 6 = -3

6. -4, 4

    y = 4 , x - 4

       4 + 2(-4) = 4 - 8 = -4

Answer:

Mean = 125.136

Median = 110

Mode = 180

Step-by-step explanation:

Given the data:

75 95 180 136 89 75 110 180 100 136 180 95 180 136 75 100 110 180 180 136 75 90

Frequency distribution:

Value(X) ___freq (F) ____cumm frequency

85 _________ 4 _______ 4

89 _________ 1 _______5

90 __________1 _______6

95 __________2 ______ 8

100 _________ 2 ______10

110 __________2______ 12

136 __________4 _____ 16

180 __________6______22

2) Using the frequency distribution :

Mean = Σfx / Σf

[(85*4) + (89*1) + (90*1) + (95*2) + (100*2) + (110*2) + (136*4) + (180*6)]/ 10

= 2753 / 22

= $125.136

Median of grouped data :

Frequency + 1 / 2 = 23/2 = 11.5 th term

The median value = $110

Mode of the data:

Most frequently occurring = 180 (frequency of 6)

The mean of the frequency distribution is $125.136, the median of the frequency distribution is $110, and the mode of the frequency distribution is $180.

Given :

a) The frequency distribution is given below:

Prices              Frequency       Cumulative Frequency

85                           4                                 4

89                            1                                 5

90                            1                                  6

95                            2                                  8

100                           2                                 10

110                            2                                  12

136                            4                                 16

180                            6                                 22

b) The mean is calculated as:

[tex]\rm Mean = \dfrac{85\times4 + 89\times1 +90\times1 +95\times 2+100\times2 +110\times2 +136\times4 +180\times6 }{10}[/tex]

Simplify the above expression.

Mean = $125.136

c) The median of the frequency distribution is calculated as:

[tex]\rm Term= Frequency + \dfrac{1}{2}=11.5[/tex]

So, the median is $110.

The mode of the frequency distribution is $180.

b

[tex]P(100 <  X  < 250 ) =0.644 [/tex]

c

 [tex]   x  = 192.1   [/tex]

Step-by-step explanation:

From the question we are told that

   The value for [tex]\alpha  =  2.6[/tex]

    The value for [tex]\beta = 220[/tex]

Generally the  Weibull distribution function is mathematically represented as

      [tex]F( x , \alpha ,  \beta ) =  \left \{  0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  x < 0} \atop { 1- e^{-(\frac{x}{\beta } )^{\alpha } }}\ \ \ \ \ \ x \ge 0} \right[/tex]

Generally the probability that a specimen's lifetime is at most 250 is mathematically represented as

      [tex]P(X \le  250 ) =  F(250, 2.7 , 220 )[/tex]

      [tex]P(X \le 250 )=1 - e^{- (\frac{250}{220} )^{2.7}}[/tex]

      [tex]P(X \le 250 ) =  1 - 0.2436[/tex]

      [tex]P(X \le 250 ) =  0.7564 [/tex]

Generally the probability that a specimen's lifetime is less than 250

      [tex]P(X <  250 ) =  F(250, 2.7 , 220 )[/tex]

      [texP(X <  250 ) =1 - e^{- (\frac{250}{220} )^{2.7}}[/tex]

      [tex]P(X <  250 )  =  1 - 0.2436[/tex]

      [tex]P(X <  250 )  =  0.7564 [/tex]    

Generally the probability that a specimen's lifetime is more than 300

     [tex]P(X >  300 ) = 1- p(X \le 300 )[/tex]

      [tex]P(X >  300 ) = 1-  F(300, 2.7 , 220 )[/tex]

      [texP(X <  300) =1- [1 - e^{- (\frac{300}{220} )^{2.7}}][/tex]

      [tex]P(X <  300 )  =  0.09922 [/tex]

Generally the probability that a specimen's lifetime is between 100 and 250 is

     [tex]P(100 <  X  < 250 ) =  P(X < 250) - P(X < 100)[/tex]

=>  [tex]P(100 <  X  < 250 ) =F(250 , 2.7 , 220 ) - F(100 , 2.7 , 220 ) [/tex]

=>  [tex]P(100 <  X  < 250 ) =(1 - e^{-(\frac{250}{220})^{2.7}}) - (1 - e^{-(\frac{100}{220})^{2.7}}) [/tex]

=>  [tex]P(100 <  X  < 250 ) = (1 - 0.244 ) - (1- 0.888)[/tex]

=>  [tex]P(100 <  X  < 250 ) =0.644 [/tex]

Generally the value  such that exactly 50% of all specimens

    [tex]P(X > x) = 1-P(X <  x) = 0.50[/tex]

=>  [tex]P(X > x) = 1- (1 - e^{- (\frac{x}{220}) ^{2.7}}) = 0.50[/tex]

=>  [tex] P(X> x ) = e^(- \frac{x}{20})^{2.7}  = 0.50 [/tex]

=>  [tex] P(X> x ) = (- \frac{x}{20})^{2.7}  = ln0.50 [/tex]

=>   [tex] P(X> x ) =  \frac{x}{20}  =[ -ln0.50 ] ^{frac{1}{2.7}}[/tex]

=>   [tex]   x  = 220[ -ln0.50 ] ^{frac{1}{2.7}}[/tex]

=>   [tex]   x  = 192.1   [/tex]
