Si se lanzan 2 dados ¿ cuantas posibilidades hay de que las caras hacia arriba sumen un numero menor que 7?

Answers

Answer 1

Answer:

P = 15/36 = 0.4166...

Step-by-step explanation:

Cada dado tiene 6 caras, con los números entre 1 y 6.

Entonces tenemos dos eventos, con 6 posibles resultados cada uno.

El número total de resultados para el evento de lanzar los dos dados, es el producto de los números de resultados para cada dado, entonces tenemos:

C = 6*6 = 36 posibles resultados.

Ahora tenemos que contar el número de resultados en donde la suma es menor a 7.

Usando la notación:

(resultado del dado 1) y (resultado del dado 2) = suma

Esos son:

1 y 1  = 2

1 y 2 = 3

1 y 3 = 4

1 y 4 = 5

1 y 5 = 6

2 y 1 = 3

2 y 2 = 4  

2 y 3 = 5

2 y 4 = 6

3 y 1 = 4

3 y 2 = 5

3 y 3 = 6

4 y 1 = 5

4 y 2 = 6

5 y 1 = 6

Hay 15 resultados donde la suma de los resultados individuales es menor a 7.

Entonces de un total de 36 posibles resultados, 15 cumplen lo que queremos, asi que la probabilidad de que las caras hacía arriba sumen un número menor que 7 son de 15 entre 36, o:

P = 15/36 = 0.4166...

Convert (4, 3π/2) to rectangular form.
A) (0,4)
B) (0, -4)
C) (-4,0)
D) (4,0)

Answers

Answer:

(0, -4)

Step-by-step explanation:

The rectangular form is expressed as;

x = rcos theta

y = rsin theta

Given the coordinate  (4, 3π/2)

r = 4

theta = 3π/2

Substitute

x = 4cos3π/2

x = 4cos270

x = 4(0)

x = 0

y= 4sin3π/2

y = 4sin270

y = 4(-1)

y = -4

Hence the required coordinate is (0, -4)

11. Keng creates a painting on a rectangular canvas with a width that is four inches longer
than the height, as shown in the diagram below.

L= h +4 and H = h


A. Write a polynomial expression, in simplified form, that represents the area of the
canvas.

Keng adds a 3-inch-wide frame around all sides of his canvas.

B. Write a polynomial expression, in simplified form, that represents the total area of the canvas and the frame.

Answers

Part A

Answer:  h^2 + 4h

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

Explanation:

We multiply the length and height to get the area

area = (length)*(height)

area = (h+4)*(h)

area = h(h+4)

area = h^2 + 4h .... apply the distributive property

The units for the area are in square inches.

===========================================================

Part B

Answer:  h^2 + 16h + 60

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

Explanation:

If we add a 3 inch frame along the border, then we're adding two copies of 3 inches along the bottom side. The h+4 along the bottom updates to h+4+3+3 = h+10 along the bottom.

Similarly, along the vertical side we'd have the h go to h+3+3 = h+6

The old rectangle that was h by h+4 is now h+6 by h+10

Multiply these expressions to find the area

area = length*width

area = (h+6)(h+10)

area = x(h+10) ..... replace h+6 with x

area = xh + 10x .... distribute

area = h( x ) + 10( x )

area = h( h+6 ) + 10( h+6 ) .... plug in x = h+6

area = h^2+6h + 10h+60 .... distribute again twice more

area = h^2 + 16h + 60

You can also use the box method or the FOIL rule as alternative routes to find the area.

The units for the area are in square inches.

The area of the canvas without the frame is h² + 4h and with frame is h²+16h+60.

What is an area?

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, Keng is painting on a rectangular canvas with a width that is four inches longer than the height,

w = h+4, height = h

Area = (length)x(height)

area = (h+4)x(h)

area = h(h+4)

area = h² + 4h

With the frame,

If we add a 3 inch frame along the border, then we're adding two copies of 3 inches along the bottom side. The h+4 along the bottom updates to h+4+3+3 = h+10 along the bottom.

Keng added a 3-inch-wide frame around the painting,

Therefore,

The h+4 will become h+4+3+3 = h+10

Similarly, along the vertical side = h+3+3 = h+6

Area = (h+10)(h+6) = h²+16h+60

Hence, the area of the canvas without the frame is h² + 4h and with frame is h²+16h+60.

Answers

Complete Question:

Write a formula for the given measure. Let P represent the perimeter in inches, and w

represent the width in inches. Identify which variable depends on which in the formula.

*The perimeter of a rectangle with a length of 5 inches

Answer:

P = 2(5 + w)

Or

P = 20 + 2w

P is the dependent variable

w is the independent variable

P depends on w.

Step-by-step explanation:

Given:

Perimeter of rectangle = P

Width of the rectangle = w

Length of the rectangle = l = 5 in.

Formula for perimeter of a rectangle = 2(length + width)

Plug in the values. Formula for the given measure would be:

P = 2(5 + w)

Or

P = 20 + 2w

P is the independent variable, while w is the dependent variable.

This is because the Perimeter (P) of the rectangle is dependent on the width (w). Whatever value of w we get would determine the value of P were would get. Therefore,

P depends on w.
