Answer:

1/8 is the probability to have exactly one head

to get the equation of any straight line, we simply need two points off of it, let's use those two points in the picture below.

[tex](\stackrel{x_1}{0}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{5}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{5}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{1}-\underset{x_1}{0}}}\implies \cfrac{3}{1}\implies 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_2=m(x-x_2) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_2}{5}=\stackrel{m}{3}(x-\stackrel{x_2}{1})[/tex]

keeping in mind that for the point-slope form, either point will do, in this case we used the second one, but the first one would have worked just the same.

Answer:

35%

Step-by-step explanation:

The required percentage of the mocha cupcakes that were sold that day is 85%.

Given that,
A bakery sells mocha cupcakes and chocolate cupcakes. One day it sold 238 mochas and 42 chocolate. What percent of the cupcakes sold that day were mocha is to be determined.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Number of mocha cupcakes = 238
Number of chocolate cupcakes = 42
Total cupcakes = 238 + 42 = 280
Percentage of mocha sold = 238/280 = 0.85 or 85%

Thus,  the required percentage of the mocha cupcakes that were sold that day is 85%.

Answer:

165

Step-by-step explanation:

The symbol [tex]\sum[/tex]  is used to denote a sum of multiple terms.

The number below [tex]\sum[/tex] is the first term.

The number above [tex]\sum[/tex] is the last term.

Each term can be determined by using the given equation.

[tex]\begin{aligned}\displaystyle \sum_{n=3}^{8}5n & =5(3)+5(4)+5(5)+5(6)+5(7)+5(8)\\ & = 5(3+4+5+6+7+8)\\ & =5(33)\\ & = 165\end{aligned}[/tex]

So

Answer:

C. 27

Step-by-step explanation:

If those two triangles are similar then look at how much one side is being increased to the other triangle. ML is similar to PQ and it increases by 1.5 to get there.

So find the side similar to RQ which is LN

1.5(x+7)=2x+5

1.5x+10.5=2x+5

5.5=0.5x

x=11

Then plug in 11 for x to find RQ which will be 27

Hey ! Buddy .

As the question is in Spanish . So we have provided your answer in English as well as in Spanish language .

( ¡Oye! Amigo, la pregunta es en español. Así que hemos proporcionado su respuesta tanto en inglés como en español. )

Answer:

Step-by-step explanation:

In this question we have given with an equation that is -6x + 71 = -4x - 1 . And have to find the value of x .

( En esta pregunta hemos dado con una ecuación que es -6x + 71 = -4x - 1 . y hay que encontrar el valor de x )

Solution : -

( Soluciones : - )

[tex] \quad : \implies - 6x + 71 = - 4 - 1[/tex]

Step 1 : Subtracting 71 on both sides :

( Paso 1 : Restando 71 en ambos lados: )

[tex]\quad : \implies - 6x + \cancel{71} - \cancel{71} = - 4x - 1 - 71[/tex]

On calculating further, We get :

( Al calcular más, obtenemos : )

[tex]\quad : \implies - 6x = - 4x - 72[/tex]

Step 2 : Adding 4x on both sides :

( Paso 2 : Sumando 4x en ambos lados: )

[tex]\quad : \implies - 6x + 4x = - \cancel{4x} + \cancel{4x } - 72[/tex]

On calculating further, We get :

( Al calcular más, obtenemos : )

[tex]\quad : \implies \cancel{-} 2x = \cancel{-}72[/tex]

Step 3 : Dividing by 2 on both sides :

( Paso 3 : Dividiendo por 2 en ambos lados: )

[tex]\quad : \implies \frac{ \cancel{2}x}{ \cancel{2} } = \cancel{\frac{72}{2} }[/tex]

On calculating further , We get :

( Al calcular más, obtenemos : )

[tex]\quad : \implies \: \green{ \boxed{ \frak{x = 36}}}[/tex]

Verifying : -

( Comprobación :- )

We are verifying our answer by substituting value of x in given equation. So ,

( Estamos verificando nuestra respuesta al sustituir el valor de x en la ecuacióndada. Asi que, )

Therefore, our solution is correct.

( Por lo tanto, nuestra solución es correcta. )

Answer:

(- [tex]\frac{1}{5}[/tex] , 0 )

Step-by-step explanation:

to find where the line crosses the x- axis, let y = 0 in the equation and solve for x

5x - 2(0) + 1 = 0

5x - 0 + 1 = 0

5x + 1 = 0 ( subtract 1 from both sides )

5x = - 1 ( divide both sides by 5 )

x = - [tex]\frac{1}{5}[/tex]

the line crosses the x- axis at (- [tex]\frac{1}{5}[/tex], 0 ) or ( - 0.2, 0 )

Answer:

(-1/5, 0).

Step-by-step explanation:

Where the line crosses the axis the value of y = 0.

5x - 2y + 1 = 0

Let y = 0, then:

5x - 2(0) + 1 = 0

5x + 1 = 0

5x = -1

x = -1/5.

So the point is (-1/5, 0).

[tex]2x+5y= 4~~~...(i)\\\\2x-2y = 18~~~...(ii)\\\\(ii) -(i):\\\\~~~~~2x-2y -2x -5y= 18 -4\\\\\implies -7y = 14\\\\\implies y = -\dfrac{14}7\\\\\implies y= -2\\\\\text{Substitute}~ y=-2~ \text{ in eq (i):}\\\\~~~~~~2x+5(-2) = 4\\\\\implies 2x-10 = 4\\\\\implies 2x = 10+4\\\\\implies 2x =14\\\\\implies x = \dfrac{14}2\\\\\implies x =7\\\\\text{Hence}~ (x,y) =(7,-2).[/tex]

Answer:

              y = -2

              x = 7

Step-by-step explanation:

     Solving simultaneous equation

         2x + 5y = 4 ---------------(I)

         2x - 2y  = 18 -----------(II)

Now, multiply equation (II) by (-1) and then add the equations. So that, 'x' will be eliminated and we can find the value of 'y'

(I)              2x + 5y = 4

(II)*(-1)      -2x  + 2y = - 18 {Now add}

                         7y = -14

                           y = -14/7       {on dividing both sides by 7}

       [tex]\sf \boxed{y= -2}[/tex]

Now plugin y = -2 in equation (I)

        2x + 5*(-2) = 4

           2x - 10   = 4

                    2x = 4 + 10     {on adding 10 to both sides}

                    2x = 14

                       x = 14/2      {Divide both sides by 2}

         [tex]\sf \boxed{x = 7}[/tex]

Step-by-step explanation:

The solution of the inequality x − y < z is x < z + y.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

An inequality,

x − y < z.

To solve for x:

Add y to both sides,

x < z + y

Therefore, the solution is x < z + y.

Answer:

ummmm..... let's see..

Step-by-step explanation:

using "Almighty formula"

{Y = –x +/– √b^2 – 4ac / 2a}

so we name all the values behind the coefficients which are; –1^2, 8 and 11

so let's assign a,b,c to these values:

a =–1, b =8, c = 11

all you just do now is to add these values to the formula

you should be having Y =1 +/– √8^2 – 4×–1×11

———————————

2×–1

Y =1 +108

———— or Y = 1–108

–2 –––––

–2

now add and divide to get Y.

− 9  

 0 6

−   6

   0  

96 divided by 3 is equal to $32.

Hence, Zack received $32 for each hockey stick.
