Answer:

The expected value of one draw is the average value of these 10 slips of paper which is:

24 / 10  =  2.4

Step-by-step explanation:

We have a bag with 10 slips of paper in it. 8 slips of paper each has a 2 on them; 2 slips of paper each has a 4 on them.

The total value of all the slips when added together is:

= (8)(2) + (2)(4)  

=  16 + 8 = 24

The expected value of one draw is the average value of these 10 slips of paper which is:

24 / 10  =  2.4  ....

Me pueden ayudar en esta ecuación bicuadratica, porfaaa: 9p⁴=—12x²—6/9
Dominik [7]

Answer:

x = -1.129i, -0.241i, 0.241i o 1.129i.

Tenga en cuenta que i = √(-1), i es el representante de un número complejo.

x = -1.129i, -0.241i, 0.241i or 1.129i.

Note that i = √(-1), i is the representative of a complex number.

Step-by-step explanation:

Pregunta correcta

¿Me pueden ayudar en esta ecuación biquadratica, por favor: 9x⁴ = —12x² - 6/9

Solución

9x⁴ = —12x² - 6/9

9x⁴ + 12x² + 6/9 = 0

multiplicar por 9

81x⁴ + 108x² + 6 = 0

Deje x² = y, entonces x⁴ = y²

81y² + 108y + 6 = 0

Resolviendo esta ecuación cuadrática

y = -0.0581 o y = -1.275

Recordemos, x² = y

x = ±√y

Si y = -0.0581

x = ± √(-0.0581) = ± 0.241i = 0.241i o -0.241i

Si y = -1.275

x = ± √(-1.275) = ± 1.129i = 1.129i o -1.129i

x = -1.129i, -0.241i, 0.241i o 1.129i.

Tenga en cuenta que i = √(-1), i es el representante de un número complejo.

¡¡¡Espero que esto ayude!!!

Correct Question

Can you help me in this biquadratic equation, please: 9x⁴ = —12x² — 6/9

Solution

9x⁴ = —12x² — 6/9

9x⁴ + 12x² + 6/9 = 0

multiply through by 9

81x⁴ + 108x² + 6 = 0

Let x² = y, then x⁴ = y²

81y² + 108y + 6 = 0

Solving this quadratic equation

y = -0.0581 or y = -1.275

Recall, x² = y

x = ±√y

If y = 0.0581

x = ±√(-0.0581) = ±0.241

If y = -1.275

x = ± √(-1.275) = ± 1.129i = 1.129i or -1.129i

Hence x = -1.129i, -0.241i, 0.241i or 1.129i.

Note that i = √(-1), i is the representative of a complex number.

Hope this Helps!!

What is the solution to the equation
gayaneshka [121]

Answer:

The solution of given equation 5(x - 6) = 2(x + 3) is given by,

x = 12

Step-by-step explanation:

It is given that,

5(x - 6) = 2(x + 3)

<u>To find the solution of given equation</u>

5(x - 6) = 2(x + 3)

5x - (5 * 6) = 2x + (2 * 3)

5x - 30 = 2x + 6

5x - 2x = 6 + 30

3x = 36

x = 36/3

x = 12

Therefore the solution of  given equation is,

x = 12

PLEASE HELP WILL GIVE BRAINLIEST TO CORRECT ANSWER <br><br> What is the slope of this line?
Alla [95]

Choice two point from the graph (look at the picture).

(0, 2) and (3, -2).

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

Substitute:

m=\dfrac{-2-2}{3-0}=\dfrac{-4}{3}=-\dfrac{4}{3}

Answer: The slope of this line is \boxed{m=-\dfrac{4}{3}}
