Si en un grupo de 10 personas se va a repartir refrescos de 10 sabores diferentes, y se sabe que hay uno de fresa y uno de piña

SashulF [63]

Respuesta: 0.011

Explicación paso a paso:

Dado que:

Número de sabor a refresco = 10

Número de sabor a piña = 1

Número de sabor a fresa = 1

P (primero es fresa) = número de sabor a fresa / número total de sabor

P (primero es fresa) = 1/10

P (el segundo es sabor a piña) = número de sabor a piña / número total de sabor

P (segundo sabor a piña) = 1/9

Probabilidades independientes:

P (primero es fresa) * P (segundo sabor a piña)

= (1/10) * (1/9)

= 1/90

= 0.011

Natalie found a tennis ball outside a tennis court. She picked up the ball and threw it over the fence into the court. The path

jeka57 [31]

To solve this exercise you must follow the proccedure below:

a) Find the maximum height of the tennis ball:

You have that the path of the ball can be represented by h=-16t²<span>+18t+5. Then:

t=-b/2a
t=-18/2(-16)
t=0.562
</span>
h=-16t²+18t+5
h=-16(0.562)²+18(0.562)+5
h=10.06

b) How long will it take to reach the ground?

h=-16t²+18t+5

h=0

-16t²+18t+5=0

You must apply the quadratic equation:

t=(-b±√(b^2-4ac))/2a

a=-16
b=18
c=5

When you substitute the values, you obtain:

t=1.35

A company has determined that when x hundred dulcimers are built, the average cost per dulcimer can be estimated by C(x)=0.2x^

damaskus [11]

Answer:

The minimum average cost per dulcimer is 150 and the minimum cost is $180.

Step-by-step explanation:

The given cost function is

$C(x)=0.2x^2-0.6x+2.250$

Differentiate the function C(x) with respect to x.

$C'(x)=0.2(2x)-0.6(1)+(0)$

$C'(x)=0.4x-0.6$

Equate C'(x)=0, to find the critical values.

$C'(x)=0$

$0.4x-0.6=0$

$0.4x=0.6$

Divide both sides by 0.4.

$x=\frac{0.6}{0.4}$

$x=1.5$

Differentiate the function C'(x) with respect to x.

$C''(x)=0.4(1)$

$C''(x)=0.4$

At x=1.5

$C''(1.5)=0.4$

The value of double derivative is positive. It means the function is minimum at x=1.5 hundred.

1.5 hundred = 150

Substitute x=1.5 in the given function to find the minimum average cost.

$C(1.5)=0.2(1.5)^2-0.6(1.5)+2.250$

$C(1.5)=1.8$

The minimum cost is 1.8 hundred dollars.

1.8 hundred dollars = $180

Therefore, the minimum average cost per dulcimer is 150 and the minimum cost is $180.

Jessica had 105 dollars to spend on 8

sattari [20]

Answer:

each book cost 11 dollars

Step-by-step explanation:
