2.49 Encuentre los errores en cad uno de las siguientes aseveraciones: a) las probabilidades de que un vendedor de automóviles venda 0,1,2 o 3 unidades en un dia dado de febrero son 0.19, 0.38, 0.29 y 0.15. Respectivamente b) la probabilidad de que llueva mañana es de 0.40 y la probabilidad de que no llueva es 0.52 c) las probabilidades de que una impresora cometa 0,1,2,3 o 4 o más errores al imprimir un documento son 0.19, 0.34, -0.25, 0.43 y 0.29 respectivamente. d) al sacar una carta de una baraja en un solo intento la probabilidad de seleccionar un corazón es ¼, la probabilidad deseleccionar una carta negra es ½, y la probabilidad de seleccionar una carta de corazones y negra es de 1/8

Answers

Answer 1

Answer:

Step-by-step explanation:

a) Si se suman las probabilidades de venta, es decir:

Probabildad de vender 0 auto ( es decir que no vendió) = 0,19

Probabildad de vender 1 auto                                              = 0,38

Probabildad de vender 2 autos                                            = 0,29

Probabildad de vender 3 autos                                            =0,15

Da por resultado:  1,01

1,01 > 1  

Ninguna probabilidad puede ser mayor que

b) LLover y no llover son condiciones excluyentes en relación al evento, es decir en relación a lluvia cualquier día o llueve o no llueve de tal forma

que las dos situaciones conforman el universo completo y deben sumar 1. en este caso el error s que suman 0.92 cando deberían sumar 1

c) No existen probabilidades negativas ( en este caso señalan -0,25 como una probabilidad

d) La probabilidad de sacar una carta de corazones es 1/4 (correcta pues hay la misma cantidad de carta de las cuatro viras  tipo ( diamante, trebo, corazones y el otro).

La mitad de las cartas son negras, de tal modo que 1/2 es correcto valor para esta probabilidad.

La probabilidad de que sea corazones y negra s 1/4*1/2  = 1/8

Luego no hay error en esta aseveración

"At an ice cream shop, customers pay $3.00 for a medium ice cream plus $0.75 per topping. At a second ice cream shop, customers pay $5.25 for a medium ice cream plus $0.25 per topping. How many toppings would a customer have to order for the ice cream to cost the same at either shop?"

Answers

Answer:hope this helps

0.75x + 3 = 0.25x + 5.25

Constants are $3 and $5.25 respectively

Topping costs $0.75 and $0.25 respectively

To have same cost the toppings number would be different as cost is different.

Suppose the number of toppings is x in one shop and y in the other, then the spending if same, we get this equation:

0.75x + 3 = 0.25y + 5.25

Constants are $3 and $5.25 respectively

Jesse wants to purchase three binders and a backpack. If the backpack costs $16, which equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase?

Answers

16+3x=y
The 16 is the cost of the backpack, which you add to the 3 binders which cost x each. This gives you the total, y.

Hope this is helpful!!

The equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase is 16+3x=y.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Jesse wants to purchase three binders and a backpack. If the backpack costs $16

From the data given in the question:

The linear equation can be framed as follows:

y = 16 + 3x

Or

16 + 3x = y

Thus, the equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase is 16+3x=y.

The options are:

16+y=3x

16+3x=y

y+3x=16

3+16x=y

Act like it is a rectangle, two lengths, and two sides.

w-6 + w-6 + w + w = 44

w-12 + 2w = 44

3w - 12 = 44

add 12 to both sides

3w=56

divide both sides by 3

Answers

Use the distributive property (of which the FOIL method is a special case):

(a - b) (a² + ab + b²)

= (a - b) a² + (a - b) ab + (a - b) b²

= (a³ - a²b) + (a²b - ab²) + (ab² - b³)

= a³ - b³

Alternatively, you can distribute the quadratic expression over each term in a - b :

(a - b) (a² + ab + b²)

= a (a² + ab + b²) - b (a² + ab + b²)

= (a³ + a²b + ab²) - (a²b + ab² + b³)

= a³ - b³

USING STRUCTURE An athletic facility is building an indoor track. The track is composed of a rectangle and two semicircles, as shown. A drawing shows an indoor track. It is shaped like a rectangle with a semi-circle on each of the shorter sides. The length of the rectangle is labeled x. The radius of each semi-circle is labeled r. A. Write a formula for the perimeter of the indoor track. $P=$ b. Solve the formula for $x$ . $x=$ Question 2 c. The perimeter of the track is 660 feet, and $r$ is 50 feet. Find $x$ . Round your answer to the nearest foot. $x=$ feet

Answers

Answer:

Step-by-step explanation:

Find the digram attached.

Perimeter of the track = perimeter of the rectangle + perimeter of the 2semicircles

Perimter of a rectangle = 2(x+r) where:

x is the length

2r is the width of the rectangle = diameter of the semicircle

Perimeter of semicircle = 2πr/2 = πr

Perimeter of 2semicirle = 2πr

Perimeter of the track = 2(x+2r) + 2πr

r is the radius if the semicircle

Expand

Perimeter of the track = 2x+4r + 2πr

Perimeter of the track = 2(x+2r+πr)

b) Given P = 2(x+2r+πr), we are to make x the subject of the formula.

P = 2x+4r+2πr

P-4r-2πr = 2x

Divide both sides by 2.

(P-4r-2πr)/2 = 2x

x = (P-4r-2πr)/2

c) Given

P = 600fr

r = 50ft

x = (600-4(50)-2π(50))/2

x = (600-200-100(3.14))/2

x = 400-314/2

x = 86/2

x = 43ft

Hence the value of x to nearest foot is 43ft
