Answer:

381.51 in^3

Step-by-step explanation:

Volume of a sphere = 4/3 x pi x r^3

r = 9/2 = 4.5

4/3 x 3.14 x 4.5^3 = 381.51 in^3

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...

Answer:

1.) 12000

2.) 6750

3.) 2.41

Step-by-step explanation:

Given the Equation :

f(t)=12,000(3/4)^t. ; where, t = time ; f(t) = worth of car at time, t

When, car was purchased, t = 0

t = 0

f(0) = 12000(3/4)^0

= 12000 * 1

= 12000

2.)

f(2) ; this mean the worth of the car after 2 years :

f(2)=12,000(3/4)^t.

12000(3/4)^2

12000 * 0.5625

= 6750

When car will be worth 6000

f(t) = 6000

f(t)=12,000(3/4)^t.

6000 = 12,000(3/4)^t

6000 / 12000 = (3/4)^t

1/2 = (3/4)^t

Take the log of both sides :

Log(0.5) = log(0.75)^t

log(0.5) = tlog(0.75)

- 0.301029 = - 0.124938t

t = - 0.301029 / - 0.124938

t = 2.4094

t = 2.41 years

Central Tendency is the statistical measure that can be used to represent all the distribution or a dataset using a single value. The most common measures of central tendency are the mode, median, and mean.

How to determine this

Mode is the value that has the highest frequency in a given data set.

So,

8.75 the highest frequency in the data set

Mode = 8.75

Median is the middle of a sorted list of numbers when arranged in ascending order.

So,

4.25, 5.75, 6.25, 6.75, 7, 7, 7.5, 8.5, 8.75 in ascending order

Median = 7

Mean is the average or the most common value in a given set of values.

Mean = 8.5 + 7 + 6.75 + 5.75 + 8.75 + 6.25 + 7 + 7.5 + 4.25/9

Mean = 61.75/9

Mean = 6.8611

Mean = 6.86 to 2 decimal place

Range is the difference between the highest value and lowest values.

Range = Maximum value - Minimum value

Range = 8.75 - 4.25

Range = 4.5

43.0 square centimeters of paper are required to make each wristband.

The curved surface of a cylinder is equal to a rectangle whose length is

2[tex]\pi[/tex]r and whose width is h.

The area of the curved surface = [tex]\pi dh[/tex].

Given

Height of wrist band =  1.8 cm

Diameter of wrist band =7.5 cm

Wrist band is a cylinder

Area of curved surface

S = [tex]\pi dh[/tex]

= 3.14 × 7.5 × 1.8

= 42.9552 ≅ 43.0 [tex]cm^{2}[/tex]

Hence, 43.0 square centimeters of paper are required to make each wristband.

Answer:

the first one. slope is 1/2 and y intercebt (b value) is positive 2.

Step-by-step explanation:

Answer:

y=1/2x+2

Step-by-step explanation:

This equation is linear because the graph is a straight line. Therefore, use the slope-intercept form y=mx+b to create the equation.

To find m (the slope), pick two points like (0,2) and (2,3). Find the change in y over the change in x: (y2-y1)/(x2-x1).

y2=3, y1=2, x2=2, x1=0

(3-2)/(2-0)= 1/2

This is the slope which means the equation is one of the first 2 options.

Next find b (the y-intercept) by finding the y value on the graph when x=0. When x=0, y=2. Therefore, b=2 and the final equation is y=1/2x+2

Given:

The equation of the parabola is:

[tex]y=x^2+6x[/tex]

To find:

The y-intercept of the parabola.

Solution:

We have,

[tex]y=x^2+6x[/tex]

Putting [tex]x=0[/tex] in the given equation, we get

[tex]y=(0)^2+6(0)[/tex]

[tex]y=0+0[/tex]

[tex]y=0[/tex]

Therefore, the y-intercept of the parabola is 0. It means the y-intercept of the given parabola is at point (0,0).
