Answer:

y - 2 = 2(x + 5)

Step-by-step explanation:

Use the point slope form: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Plug in the point and slope:

y - y1 = m(x - x1)

y - 2 = 2(x + 5) is the equation

             [tex]\sqrt[4]{(16)^{-2} }[/tex]

Now let us solve this;

           [tex]\sqrt[4]{(16)^{-2} }[/tex];

     the fourth root can be expressed  as the power of    [tex]\frac{1}{4}[/tex] ;

    [tex]\sqrt[4]{(16)^{-2} }[/tex]   =     [(16)⁻²][tex]^{\frac{1}{4} }[/tex]

                     =  (16)[tex]^{-2 x \frac{1}{4} }[/tex]

                      = (16)[tex]^{\frac{-1}{2} }[/tex]

                      =     [tex]\frac{1}{16^{\frac{1}{2} } }[/tex]

                     =    [tex]\frac{1}{\sqrt{16} }[/tex]

                     =  [tex]\frac{1}{4}[/tex]

The solution is [tex]\frac{1}{4}[/tex]

Answer:

Las coordenadas del punto son P([tex]2.\overline 3[/tex], 1)

Step-by-step explanation:

Las coordenadas de los extremos de la pieza de madera son A (5, 3) y B (-3, -3)

El punto, P, en el que se agregará la muesca = 1/3 de la longitud de AB

Por tanto, las coordenadas del punto, tomando A como punto de referencia, se dan como sigue;

P (5 + (-3 - 5) × 1/3, 3 + (-3 - 3) × 1/3) = P([tex]2.\overline 3[/tex], 1)

Las coordenadas del punto son P([tex]2.\overline 3[/tex], 1).

Answer:

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    4/7*x+5/14*x-(39)=0

Simplify 5/14

((4/7• x) +  (5/14 • x)) -  39  = 0

Simplify 4/7

  4         5x    

 ((— • x) +  ——) -  39  = 0

  Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      4x • 2

  ——————————————————  =   ——————

        L.C.M               14  

  R. Mult. • R. Num.      5x

  ——————————————————  =   ——

        L.C.M             14

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

4x • 2 + 5x     13x

———————————  =  ———

    14          14

 13x    

 ——— -  39  = 0

 14    

 Subtracting a whole from a fraction

Rewrite the whole as a fraction using  14  as the denominator :

         39     39 • 14

   39 =  ——  =  ———————

         1        14  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

13x - (39 • 14)     13x - 546

———————————————  =  —————————

      14               14    

 Pull out like factors :

  13x - 546  =   13 • (x - 42)

13 • (x - 42)

 —————————————  = 0

      14  

 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 13•(x-42)

 ————————— • 14 = 0 • 14

    14    

Now, on the left hand side, the  14  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  13  •  (x-42)  = 0

Solve :    13   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solve  :    x-42 = 0

Add  42  to both sides of the equation :

                     x = 42

Answer:

it's C

Step-by-step explanation:

The correct answer is: The equation y = 54.16 + 0.87x is called the least-squares regression line because it makes the sum of the squared residuals as small as possible.

The least-squares regression line is a line that best fits the given data points by minimizing the sum of the squared residuals. Residuals are the vertical distances between the actual data points and the predicted values on the regression line. By minimizing the sum of the squared residuals, the line is able to provide the best overall fit to the data.

Therefore, the least-squares regression line aims to minimize the differences between the predicted values and the actual data points, making the sum of the squared residuals as small as possible.

Answer:

The answer would be 48 since it would be 4 x 12

Answer:

$15

Step-by-step explanation:

If the 5 people where each paying $12 to rent the equipment, that means the cost of the equipment can be found multiplying 5 and 12 to get 60. Now that we know that the cost of the equipment is $60, if one person bailed out, there are now 4 people to rent it. You can find how much each person pays if they each pay the same amount by dividing 60 by 4. Once you do                      $60 ÷ 4 people = 15. So each person pays $15.

Answer:

0.82%

Step-by-step explanation:

First find the z-score.

z = (x − μ) / σ

z = (72 − 60) / 5

z = 2.4

Use a chart or calculator to find the probability.

P(Z > 2.4) = 1 − P(Z < 2.4)

P(Z > 2.4) = 1 − 0.9918

P(Z > 2.4) = 0.0082

Hence, the probability of time does it take longer than [tex]72[/tex] minutes if the standard deviation is [tex]5[/tex] minutes is [tex]0.82[/tex]%.

What is the probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Here given that,

If an hourglass takes an average of one hour to empty a full cycle.

Now, First find the z-score.

[tex]z = (x-[/tex] μ[tex])[/tex]/σ

[tex]z = \frac{72 - 60}{5}\\z = 2.4[/tex]

Now, using the calculator to find out the probability.

[tex]P(Z > 2.4) = 1 - P(Z < 2.4)\\\\P(Z > 2.4) = 1 - 0.9918\\\\P(Z > 2.4) = 0.0082[/tex]

Thus,

[tex]0.0082(100)=0.82[/tex]%

Hence, the probability of time does it take longer than [tex]72[/tex] minutes if the standard deviation is [tex]5[/tex] minutes is [tex]0.82[/tex]%.
