The value  is [tex]t = 2.51 [/tex]

Step-by-step explanation:

From the question we are told that

   From the question we are told that  

    The first sample mean is  [tex]\= x_1 = 71.1[/tex]

     The first standard deviation is [tex]\sigma _1 = 19.4[/tex]

     The  second sample mean is  [tex]\= x_2 = 63.4[/tex]

     The second sample  deviation is  [tex]\sigma_2 = 10.5[/tex]

     The first sample size is  [tex]n_1 = 55[/tex]

      The second sample size is  [tex]n_2 = 46[/tex]

Generally the test statistics is mathematically represented as

         [tex]t = \frac{\= x_1 - \= x_2 }{ \sqrt{\frac{s_1^2 }{n_1} +\frac{s_2^2 }{n_2} } }[/tex]

=>   [tex]t = \frac{71.1 - 63.4 }{ \sqrt{\frac{19.4^2 }{55}  +\frac{10.5^2 }{46}   } }[/tex]

=>   [tex]t = 2.51 [/tex]

Answer:

(6,3)

Step-by-step explanation:

If you reflect (-4,3) over the y-axis it is going to become (4,3).

Then, if you move it 2 units to the right, it becomes (6,3)

The coordinates of the point  (-4,3) after reflection and translation will be ( 6, 3 ).

The process of changing the location of the image on the coordinate system will be known as the translation.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the point  (-4,3) is the image of A after a reflection using the y-axis, then a translation of two units to the right.

Reflection of point ( -4 , 3 ) ⇒ ( 4 , 3 )

A translation of two units to the right ⇒ ( 4 + 2, 3 ) ⇒ ( 6, 3 )

Therefore, the coordinates of the point  (-4,3) after reflection and translation will be ( 6, 3 ).

Answer:

[tex]m=1[/tex]

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in the 2 coordinates into the slope formula to find slope m:

(1, -3)

(4, 0)

[tex]m=\frac{0-(-3)}{4-1}[/tex]

[tex]m=\frac{0+3}{3}[/tex]

Answer:

1.18 i think

Step-by-step explanation:

Answer:

I think that to go to the temperature you you can draw a straight line then on one side write negative the other side positive that the centre write 0 then locate -14 and 12 so negative 14 will fall on the negative side and 12 will fall on the positive side then count from -14 up to positive 12 and you'll find that it changed by 26°

Answer:

Step-by-step explanation:

Supplementary angles add up to 180°

Angles

and

Answer:

x = 35

77 degrees

Step-by-step explanation:

Supplementary angles mean that two angles add up to measure 180 degrees.

Solve for x.

(3x - 2) + (2x + 7) = 180

~Combine like terms

5x + 5 = 180

~Subtract 5 to both sides

5x = 175

~Divide 5 to both sides

x = 35

Angle 1:

3x - 2

3(35) - 2

105 - 2

103 degrees

Angle 2:

2x + 7

2(35) + 7

70 + 7

77 degrees

103 > 77

The smaller angle is 77.

Best of Luck!

Step-by-step explanation

The answers in bold is what was required from the question.

the null hypothesis using symbol:-

H₀ : μ = 11.80

the alternative hypothesis using symbol:-

H₁:  μ ≠ 11.80

This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.

Alpha level = 0.05

Sample size = n

Degree of freedom = n-1 = 40-1 = 39

To use the t distribution we will have to find the critical value from the t table this value is 1.685

But the question does not have sample mean and sample standard deviation. So I was unable to solve for the standard error

Answer:

a

   [tex]Y  = \$ 30000[/tex]

b

  [tex]Y  = \$ 11250 [/tex]

c

  [tex]X  = \$  36250  [/tex]

Step-by-step explanation:

From the question we are told that

   The annual taxable income is [tex]A = \$ 300,000[/tex]

   The tax rate for next year is  [tex]r =  0.25[/tex]

   The  present tax rate is  [tex]R =  0.35[/tex]

Generally the present amount of tax collected from Ms Benoit is  

         [tex]K =  A   * R[/tex]

        [tex]K =  300000  * 0.35 [/tex]

=>       [tex]K =   \$105000 [/tex]

Generally the  amount of tax collected from Ms Benoit nest year  is

          [tex]B =  A   * r[/tex]

        [tex]B =  300000  * 0.25 [/tex]

=>       [tex]B =   \$75000  [/tex]        

The  reduction in the tax amount is mathematically represented as

       [tex]Y  =  K  - B[/tex]

=>     [tex]Y  =  105000  - 75000[/tex]

=>    [tex]Y  = \$ 30000[/tex]

Generally the tax amount of next year when the income is  $375,000 is mathematically represented as

    [tex]M  =  375 000   *   r[/tex]

=>    [tex]M  =  375 000   *   0.25[/tex]

=>     [tex]M  =  \$ 93 750 [/tex]

The  reduction in the tax amount is mathematically represented as when  the income for next year  is  $375,000

             [tex]Z  =  K  - M[/tex]

=>     [tex]Z  =  105000  -93 750 [/tex]

=>    [tex]Z  = \$ 11250 [/tex]

Generally the tax amount of next year when the income is  $275,000 is mathematically represented as

    [tex]U  =  275,000   *   r[/tex]

=>    [tex]U  =  275 000*   0.25[/tex]

=>     [tex]M  =  \$ 68 750  [/tex]

The  reduction in the tax amount is mathematically represented as when  the income for next year  is  $275,000

             [tex]X  =  K  - M[/tex]

=>     [tex]X  =  105000  -68 750 [/tex]

=>    [tex]X  = \$  36250  [/tex]
