Answer:

About 0.72

Step-by-step explanation:

Given the data:

With device : 22.6, 23.4, 28.4, 29, 29.3, 20.0

Without device :26.9, 24.4, 20.8, 20.8, 20.2, 26.0, 28.1, 25.6

Using calculator:

With device data:

Sample size (n1) = 6

Degree of freedom (df1) = 6 - 1 = 5

Mean(m1) = 25.45

Variance (s²1) = 15.631

Without device data:

Sample size (n2) = 8

Degree of freedom (df2) = n - 1 = 7

Mean (m2) = 24.1

Variance (s²2) = 9.54

s²t = ((df1/(df1 + df2)) * s²1) + ((df2/(df1 + df2)) * s²2)

s²t = ((5/(5+7)*15.63) + ((7/(5+7))*9.54)

= ((5/12) * 15.63) + ((7/12) * 9.54) = 12.0775

s²m1 = s²t/n1 = 12.0775/6 = 2.0123

s²m2 = s²t/n2 = 12.0775/8 = 1.511

T - statistic :

Tstat = (m1 - m2)/√(s²m1 + s²m2)

Tstat = (25.45 - 24.10) / √(2.0123 + 1.511)

Tstat= 1.350/√3.5233

Tstat = 1.350 / 1.8770455

Tstat = 0.7192153 = 0.72

In this exercise we want to use the knowledge of statistics and probability to calculate the statistical test that counts:

[tex]0.72[/tex]

First, we have to separate the data informed in the text and analyze it, like this:

Now doing with the device data calculations, we will find that:

Now doing without device data calculations, we will find that:

So to calculate the variance of the population we will use the data given above:

[tex]s~2t = ((df_1/(df_1 + df_2)) * s^2_1) + ((df_2/(df_1 + df_2)) * s^2_2)\\s^2t = ((5/(5+7)*15.63) + ((7/(5+7))*9.54)\\= ((5/12) * 15.63) + ((7/12) * 9.54) = 12.0775\\s^2m_1 = s^2t/n_1 = 12.0775/6 = 2.0123\\s^2m_2 = s^2t/n_2 = 12.0775/8 = 1.511[/tex]

For the calculation of the statistical test, we found that:

[tex]Tstat = (m_1 - m_2)/\sqrt{(s^2m_1 + s^2m_2)} \\Tstat = (25.45 - 24.10) / \sqrt{(2.0123 + 1.511)} \\Tstat= 1.350/\sqrt{3.5233} \\Tstat = 1.350 / 1.8770455\\Tstat = 0.7192153 = 0.72[/tex]

Answer:

B.

Step-by-step explanation:

The lines positioning shows a negative slope already, so it cant be C or D

Slope is a rise over run basis. You can check this just from points alone, the line would be much steeper if the slope was -2.

Hope this helps!

Answer:

1) 50 Kg = 110 Ibs

2) 50 Ibs = 250/11 Kg

Step-by-step explanation:

Let us use the ratio method to solve this question

1)

→  Kg   →  Ibs

→  1      →  2.2

→  50   →  x

By using cross multiplication

∵ 1 × x = 50 × 2.2

∴ x = 110 Ibs

∴ 50 Kg = 110 Ibs

2)

Similar we can find the other part

→  Kg   →  Ibs

→  1      →  2.2

→  y     →  50

By using cross multiplication

∵ y × 2.2 = 1 × 50

∴ 2.2y = 50

→ Divide both sides by 2.2 to find y

∴ [tex]\frac{2.2y}{2.2}=\frac{50}{2.2}[/tex]

∴ y = 250/11 Kg ⇒ 22.7272 Kg

∴ 50 Ibs = 250/11 Kg

Hi there !

DBC + CBV = 180°

DBC + BDC + DCB = 180°  }=> VBC = BDC + DCB

replace

20x + 5 = 9x - 2 + 40

solve the equation

20x - 9x = 40 - 2 - 5

11x = 33

x = 33 : 11

x = 3

Good luck !

In case there is no double entry system is followed, profit can be calculated by comparing the opening and closing capital. In the given situation this can be calculated as:

Opening Capital Rs.200000

Add: Capital Introduced Rs.200000

Add: Profit for the year Rs. 250000

Less: Loss for the year Rs.NIL

Less: Drawings Rs. 30000

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

Capital at the end of the year Rs.620000

Loan taken is a liability and loan given is asset, that will not affect the capital.

Answer:

cbe

Step-by-step explanation:

The angle whose measure is equal to the sum of the measures of ∠BAC and ∠BCA is ∠CBE, the correct option is B.

An angle is formed by two rays called the arms of the angle meeting at a common endpoint called the vertex of the angle.

The angle whose measure is less than 90 degree is called the acute angle, whose measure is equal to 90 degree is called right angle, the angle whose measure is greater than 90 degree is called obtuse angle.

The ∠BAC and ∠BCA are the interior angles of the triangle,

According to the theorem of exterior angle, The measure of the exterior angle is equal to the sum of the two opposite interior angles.

The sum of the angles, ∠BAC and ∠BCA is equal to the opposite exterior angle, i.e. ∠CBE

∠CBE =  ∠BAC + ∠BCA

Step-by-step explanation:

Given parameters:

Coordinates of end points =  (2, -3) and (-6,5).​

 Slope of line  = [tex]\frac{9}{7}[/tex]

Unknown:

Equation of the line with the given slope = ?

Solution:

Let us find the coordinates of the mid-point of the line given.

   Since the end points are (2, -3) and (-6,5);

   Midpoint;

            x, y = [tex]\frac{x_{1} + x_{2} }{2}[/tex] , [tex]\frac{y_{1} + y_{2} }{2}[/tex]  

            x, y = [tex]\frac{2 + (-6)}{2}[/tex]  ,  [tex]\frac{-3 + 5}{2}[/tex]   = -2 , 1

The coordinate of the mid point = -2,1

Equation of a line is;

                  y = mx + c

x and y are the coordinates

     m is the slope

     c is the y intercept

We need to find c in order to fully develop our equation;

             y = mx + c

              y = 1 , x = -2 and m = [tex]\frac{9}{7}[/tex]

So,

           1 = [tex]\frac{9}{7}[/tex] x (-2) + c

            c  = 1 + [tex]\frac{18}{7}[/tex]   = [tex]\frac{25}{7}[/tex]

Now, the equation of the line is;

              y = -2x + [tex]\frac{25}{7}[/tex]  

Multiply through by 7,

            7y = -14x + 25

The equation of the line is 7y = -14x + 25
