Drag The Tiles To The Correct Boxes To Complete The Pairs. A Team Of 10 Players Is To Be Selected From

Answers

Answer 1

Answer:

The selection of r objects out of n is done in

many ways.

The total number of selections 10 that we can make from 6+7=13 students is  

thus, the sample space of the experiment is 286

A.  

"The probability that a randomly chosen team includes all 6 girls in the class."

total number of group of 10 which include all girls is C(7, 4), because the girls are fixed, and the remaining 4 is to be completed from the 7 boys, which can be done in C(7, 4) many ways.

P(all 6 girls chosen)=35/286=0.12

B.

"The probability that a randomly chosen team has 3 girls and 7 boys."

with the same logic as in A, the number of groups were all 7 boys are in, is  

so the probability is 20/286=0.07

C.

"The probability that a randomly chosen team has either 4 or 6 boys."

case 1: the team has 4 boys and 6 girls

this was already calculated in part A, it is 0.12.

case 2, the team has 6 boys and 4 girls.

there C(7, 6)*C(6, 4) ,many ways of doing this, because any selection of the boys which can be done in C(7, 6) ways, can be combined with any selection of the girls.  

the probability is 105/286=0.367

since  case 1 and case 2 are disjoint, that is either one or the other happen, then we add the probabilities:

0.12+0.367=0.487 (approximately = 0.49)

D.

"The probability that a randomly chosen team has 5 girls and 5 boys."

selecting 5 boys and 5 girls can be done in  

many ways,

so the probability is 126/286=0.44

¿En què situaciones usamos los nùmeros enteros positivos y negativos, escribe 2 ejemplos de cada uno? Por favor para ahora hocino me jalan :(

Answers

Respuesta:

Los enteros positivos, o números enteros, se utilizan de muchas maneras durante la vida diaria. Los números de carretera se contabilizan junto con los límites de velocidad de la carretera. Los enteros se utilizan para comprender qué velocidad conducir en una carretera determinada. Los números en los relojes se utilizan para entender la hora y para configurar las alarmas del reloj. Hay números en edificios y casas para identificar direcciones y números para los niveles de piso dentro de los edificios. Los mapas utilizan enteros para proporcionar dirección e información. Los enteros negativos pueden ser menos obvios para su uso en la vida cotidiana. Algunos ejemplos de uso negativo de enteros incluyen las lecturas del termómetro, manteniendo la puntuación en un juego de hockey, altitud y bancos. Aunque todos estos ejemplos utilizan enteros positivos, también utilizan enteros negativos. Un termómetro utiliza negativo enteros para representar temperaturas por debajo de cero. En hockey, cuando el otro equipo anota en la línea del primer equipo, es un menos, pero cuando el primer equipo anota, es un plus. La altitud que está por debajo del nivel del mar está representada con números negativos. Los bancos y las cooperativas de crédito representan débitos con enteros negativos y créditos con enteros positivos.

Answer:

[tex]\theta = \frac{\pi}{2}[/tex]

Step-by-step explanation:

Given

[tex]\sin(\theta) = 1[/tex]

[tex]0 < \theta < \pi[/tex]

Required

Find [tex]\theta[/tex]

[tex]0 < \theta < \pi[/tex] implies that [tex]\theta[/tex] is between 0 and 180 degrees

[tex]\sin(\theta) = 1[/tex]

Take arcsin of both sides

[tex]\theta = sin^{-1}(1)[/tex]

This gives:

[tex]\theta = \frac{\pi}{2}[/tex]

Convert to degrees

[tex]\theta = \frac{\pi}{2} * \frac{180}{\pi}[/tex]

[tex]\theta = 90[/tex]

We have:

[tex]0 < \theta < \pi[/tex] or [tex]0 < \theta < 180[/tex]

To get other values of [tex]\theta[/tex]

We use:

[tex]\sin(\theta) = \sin(180 - \theta)[/tex]

Substitute: [tex]\theta = 90[/tex]

[tex]\sin(90) = \sin(180 - 90)[/tex]

[tex]\sin(90) = \sin(90)[/tex]

This means that there are no other values of [tex]\theta[/tex] in the given range

What is Area?

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.

We have side of square is √27 inches.

So, the Area of Square

= side x side

= √27 x √27

= 27 inches²

Find the perimeter of the shaded region. Keep answer in exact form. rectangle with two semi circles within it. Semi circle have a diameter of 6 and regtangle has a lenght of 13

Answers

Answer:

31.16

Step-by-step explanation:

Perimeter of the shaded portion = Perimeter of the rectangle - Perimeter of the 2 circles

Length of rectangle = 13

Width = 2d

d is the diameter of the circle = 2(6) = 12

Perimeter of the rectangle = 2(L+W)

Perimeter of the rectangle = 2(13+12)

Perimeter of the rectangle = 2(25)

Perimeter of the rectangle = 50

Perimeter of the semi-circle = πd/2

Perimeter of the circle = 3.14(6)/2

Perimeter of the circle = 18.84/2

Perimeter of the 2 circles = 2(18.84)/2

Perimeter of the 2 circles = 18.84

Perimeter of the shaded portion = 50 - 18.84

Perimeter of the shaded portion = 31.16
