Answer:

When the  sample size is  [tex]n_1 = 5[/tex] ,

   [tex]P( X < 11) = 0.9875[/tex]

When the  sample size is  [tex]n_2 = 6[/tex] ,

   [tex]P( X < 11) = 0.993[/tex]

Step-by-step explanation:

From the question we are told that

  The mean is  [tex]\mu = 9 \ min[/tex]  

   The standard deviation is [tex]\sigma = 2 \ min[/tex]

    The first sample size is  [tex]n_1 = 5[/tex]

    The second sample size is  [tex]n_2 = 6[/tex]

Generally the standard error of the mean is mathematically represented as

     [tex]\sigma_{x} = \frac{\sigma}{ \sqrt{n} }[/tex]

=>   [tex]\sigma_{x} = \frac{2}{ \sqrt{5} }[/tex]  

When the  sample size is  [tex]n_1 = 5[/tex] ,

Generally the standard error of the mean is mathematically represented as

     [tex]\sigma_{x} = \frac{\sigma}{ \sqrt{n} }[/tex]

=>   [tex]\sigma_{x} = \frac{2}{ \sqrt{5} }[/tex]  

=>   [tex]\sigma_{x} = 0.894[/tex]  

Generally the probability that the sample average amount of time taken on each day is at most 11 min is mathematically represented as

      [tex]P( X < 11) = P( \frac{X - \mu }{\sigma } < \frac{11 - 9 }{0.8944 } )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

      [tex]P( X < 11) = P( Z < 2.24 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  2.24 is

      [tex]P( Z < 2.24 ) = 0.9875[/tex]

=>   [tex]P( X < 11) = 0.9875[/tex]

When the  sample size is  [tex]n_2 = 6[/tex] ,

Generally the standard error of the mean is mathematically represented as

     [tex]\sigma_{x} = \frac{\sigma}{ \sqrt{n} }[/tex]

=>   [tex]\sigma_{x} = \frac{2}{ \sqrt{6} }[/tex]  

=>   [tex]\sigma_{x} = 0.816[/tex]  

Generally the probability that the sample average amount of time taken on each day is at most 11 min is mathematically represented as

      [tex]P( X < 11) = P( \frac{X - \mu }{\sigma } < \frac{11 - 9 }{0.816 } )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

      [tex]P( X < 11) = P( Z < 2.45 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  2.24 is

      [tex]P( Z < 2.45 ) = 0.993[/tex]

=>   [tex]P( X < 11) = 0.993[/tex]

Step-by-step explanation:

Answer/Step-by-step explanation:

Since ∆PHS ≅ ∆CNF, therefore:

<P ≅ <C,

<H ≅ <N

<S ≅ <F

Thus:

Since, <P ≅ <C, therefore,

36° = (4z - 32)°

36 = 4z - 32

Add 32 to both sides

36 + 32 = 4z

68 = 4z

Divide both sides by 4

68/4 = z

17 = z

z = 17

Since <H ≅ <N, therefore:

6x - 29 = 115°

Add 29 to both sides

6x = 115 + 29

6x = 144

Divide both sides by 6

x = 114/6

x = 24

m<F + m<C + m<N = 180° (sum of ∆)

(3y - 1) + (4z - 32) + 115 = 180 (substitution)

Plug in the value of z and solve for y

3y - 1 + 4(17) - 32 + 115 = 180

3y - 1 + 68 - 32 + 115 = 180

3y + 150 = 180

Subtract 150 from both sides

3y = 180 - 150

3y = 30

y = 10

The value of x, y and z are 24, 10 and 17 respectively.

PHS≅CNF

Therefore,

∠P ≅ ∠C

∠H ≅ ∠N

∠S ≅ ∠F

36 = 4z - 32

36 + 32 = 4z

4z = 68

z = 68 / 4

z = 17

6x - 29 = 115

6x = 115 + 29

x = 144 / 6

x = 24

3y - 1 = 180 - 115 - (4z - 32)

3y - 1 = 180 - 115 - 4z + 32

3y - 1 = 97 - 4(17)

3y - 1 = 29

3y = 30

y = 30 / 3

y = 10

The solutions to the quadratic equation using the quadratic formula will be:

[tex]x=\frac{1}{2},\:x=\frac{1}{4}[/tex]

Step-by-step explanation:

Given the equation

[tex]8x^2-6x+1=0[/tex]

solving with the quadratic formula

[tex]\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}[/tex]

[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]\mathrm{For\:}\quad a=8,\:b=-6,\:c=1[/tex]

[tex]x_{1,\:2}=\frac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:8\cdot \:1}}{2\cdot \:8}[/tex]

as

[tex]\sqrt{\left(-6\right)^2-4\cdot \:8\cdot \:1}=2[/tex]

so

[tex]x_{1,\:2}=\frac{-\left(-6\right)\pm \:2}{2\cdot \:8}[/tex]

Separating the solution

[tex]x_1=\frac{-\left(-6\right)+2}{2\cdot \:8},\:x_2=\frac{-\left(-6\right)-2}{2\cdot \:8}[/tex]

solving

[tex]x_1=\frac{-\left(-6\right)+2}{2\cdot \:\:8}[/tex]

    [tex]=\frac{6+2}{2\cdot \:8}[/tex]

   [tex]=\frac{8}{16}[/tex]

   [tex]=\frac{1}{2}[/tex]

and

[tex]x_2=\frac{-\left(-6\right)-2}{2\cdot \:8}[/tex]

   [tex]=\frac{6-2}{2\cdot \:\:\:8}[/tex]

    [tex]=\frac{4}{16}[/tex]

Answer:

1/4 1/2

Step-by-step explanation:

Answer:

1/9, 1/8, 1/7,1/5

Step-by-step explanation:

The fraction between 1/6 and 1/4 are 17/100, 19/100,1/5, and 21/100.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

For example a fraction 1/5 here 1 will be the numerator and 5 will be denominated.

Given the fraction

1/6 = 0.16

1/4 = 0.25

Now all values in between of it will be the answer.

So,

0.17 = 17/100

0.19 = 19/100

0.20 = 20/100 = 1/5

0.21 = 21/100

Hence "The fraction between 1/6 and 1/4 are 17/100, 19/100,1/5, and 21/100".

Solve the given equation for y

2y = 3x - 10

y = (3x-10)/2 ..... divide both sides by 2

y = (3x)/2 - 10/2

y = (3/2)x - 5

The equation is in y = mx+b form with m = 3/2 as the slope.

The perpendicular slope is -2/3 because we flip the fraction and the sign from positive to negative.

Note how multiplying the original slope 3/2 and the perpendicular slope -2/3 leads to -1

(3/2)*(-2/3) = -1

This is true for any pair of perpendicular lines, assuming neither line is vertical.

Figure (c)

Step-by-step explanation:

a). Angles in the figure attached are the linear pair of angles.

    Since, sum of the linear pair of angles is 180°.

    2x + 38 = 180°

b). Angles given in this figure are the vertically opposite angles.

   Since, vertically opposite angles are equal in measure.

   2x = 38°

c). There are three angles given the picture.

   Since these angles are formed at a point of a line, sum of angles will be 180°.

   90° + 38° + 2x = 180°

   2x + 38 = 180 - 90

   2x + 38 = 90°

Therefore, figure (c) shows the equation.
