P(x) 0.3 0.2 ? 0.4
(b) compute the mean of random variable x

Answers

Answer:

2.6

Step-by-step explanation:

Given :

x 1 2 3 4

P(x) 0.3 0.2 ? 0.4

Σp(x) = 1

Hence, 0.3 + 0.2 +? + 0.4 = 1

0.9 +? = 1

? = 1 - 0.9

? = 0.1

For the mean :

E(X) = ΣX*P(X)

(1 * 0.3) + (2 * 0.2) + (3 *0.1) + (4* 0.4)

0.3 + 0.4 + 0.3 + 1.6 = 2.6

Hence, the mean = 2.6

Given a cone with height of 10 cm and a base radius of 9 cm, what is the volume of the cone? Use 3.14 for π. Round your answer to the nearest tenth.

Answers

Answer:

848 is the answer

The volume of the cone is approximately 282.74 cubic centimeters.

What is a cone?

It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.

We have,

The formula for the volume of a cone is V = (1/3)πr²h,

where r is the radius of the base and h is the height of the cone.

Substituting the given values.V = (1/3)π(9 cm)²(10 cm)

V = (1/3)π(81 cm²)(10 cm)

V = (1/3)π(810 cm³)

V = (270/3)π cm³

V = 90π cm³

V ≈ 282.74 cm³ (rounded to the nearest tenth)

Therefore,

The volume of the cone is approximately 282.74 cubic centimeters.

Answers

Answer:

options C -x^2/3z

Step-by-step explanation:

this is the correct answer after we cancelled them

Answer:

C

Step-by-step explanation:

This requires you to know the law of quotient for exponents. For this I recommend separating everything with the same variable into its own fraction to make it easier so you have (-2x^4/6x^2), (y^2/y^2), (z/z^2). Then to simplify you divide the coefficients and signs like normal but for the exponents, you subtract the exponent of the numerator from the denominator. This gives

(-x^2 / 3), (1), and ( 1/z), which you can multiple together to get c.

Hope this helps. Ask if you need me to clarify something.

[tex]V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}][/tex] or [tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

Step-by-step explanation:

Given

[tex]Ratio = \frac{\pi}{4}[/tex]

See attachment for complete question

Required

Determine the volume of the cone

The volume of a square pyramid is:

[tex]V = \frac{a^2h}{3}[/tex]

Where

a = base dimension

From the attachment, the base dimension of the square pyramid is 2r.

So:

[tex]a = 2r[/tex]

The volume becomes;

[tex]V = \frac{(2r)^2h}{3}[/tex]

To calculate the volume of the cone, we simply multiply the given ratio and the volume of the prism.

So, we have:

[tex]V_2 = Ratio * V[/tex]

[tex]V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}][/tex]

[tex]V_2 = \frac{\pi}{4} * \frac{(2r)^2h}{3}[/tex]

Open bracket;

[tex]V_2 = \frac{\pi}{4} * \frac{4r^2h}{3}[/tex]

Cancel out 4

[tex]V_2 = \pi * \frac{r^2h}{3}[/tex]

The above can be written as:

[tex]V_2 = \frac{1}{3} * \pi r^2h[/tex]

[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

So, we have:

[tex]V_2 = \frac{\pi}{4} [ \frac{(2r)^2h}{3}][/tex]

or

[tex]V_2 = \frac{1}{3}\pi r^2h[/tex]

Find the area of the shaded region

Answers

Answer:

249.9

Step-by-step explanation:

Area of the shaded region is 223.72 square units.

Step-by-step explanation:

Area of the shaded region = Area of parallelogram - Area of triangle

Area of the parallelogram = base x height

= 23.8 x 15

= 357 square feet

Area of triangle = \frac{1}{2}

2

1

x base x height

Let the height of the triangle be represented by h, applying the Pythagoras theorem;

23.8^{2}23.8

2

= 21^{2}21

2

+ h^{2}h

2

566.44 = 441 + h^{2}h2

h^{2}h

2= 125.44

h = \sqrt{125.44}

125.44

= 11.2

h = 11.2

Area of the triangle = \frac{1}{2}

21 x 23.8 x 11.2 = 133.28

Area of shaded region = 357 - 133.28

= 223.72

Area of the shaded region is 223.72 square units.

Elisa y su sombra forman un ángulo recto . La sombra anide 1,2 m y el ángulo con el que se ve la parte superior de su cabeza desde el extremo de la sombra mide 54° 50° . Calcular la altura de Elisa

Answers

Answer:

h = 1.65 m

Step-by-step explanation:

Me parece que el problema está mal formulado por lo siguiente:

El angulo al que se refiere el problema es 54°  o es 50°  o es 54°,50´

Como resolver el problema en cualquier caso.

Si Elisa y su sombra forman un angulo recto, entonces Elisa, su sombra y la distancia entre la cabeza de Eliza y el final de su sombra forman un triangulo rectangulo. Para el cual entonces solo es necesario buscar la tangente del angulo ( cateto opuesto sobre cateto adyacente) como conocemos el cateto adyacente ( la sombra de Elisa ) calculamos la altura de Elisa (h).

Asumamos que el angulo es de 54°  entonces

tang 54° = 1.3763

tang 54° = 1.3763  = h/1.2

h = 1,3763*1,2  m

h = 1.65 m

De igual manera se procedería si el angulo es de 50° ( en este caso la    tang 50° = 1.1917
