Para reunir dinero para su gira de estudios , los alumnos de un curso deciden vender números de una rifa que se encuentran numeradas del 1 al 100 ¿Cual es la probabilidad de ganar en la rifa si se compran todos los numeros que sean multiplos de 3 o de 5?

Answers

Answer 1

Respuesta:

0.53

Explicación:

Para calcular la posibilidad del evento A: "ganar la rifa comprando todos los números múltiplos de 3 o 5", debemos usar la siguiente fórmula.

P(A) = casos favorables / casos posibles

Evaluemos primero todos los casos que son múltiplos de 3, entre 1 y 100: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99. En total son 33.

Ahora, evaluemos todos los casos que son múltiplos de 3, entre 1 y 100: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100. En total son 20.

El número total de casos favorables es 33 + 20 = 53.

El número de casos posibles es el total de números de 1 a 100, es decir 100.

Luego P(A) = 53/100 = 0.53.

Answers

Given:

The expression is:

[tex]36x^3-22x^2-\_\_\_[/tex]

To find:

The values for the blank so that the greatest common factor of the resulting polynomial is [tex]2x[/tex].

Solution:

We have,

[tex]36x^3-22x^2-\_\_\_[/tex]

If the greatest common factor of the resulting polynomial is [tex]2x[/tex], then 2 and x must be factors of missing value.

In option A, 2 is a factor of 2 but [tex]x[/tex] is not a factor of 2. So, this option is incorrect.

In option B, 2 and [tex]x[/tex] are factors of [tex]4xy[/tex]. So, this option is correct.

In option C, 2 and [tex]x[/tex] are factors of [tex]12x[/tex]. So, this option is correct.

In option D, 2 is a factor of 24 but [tex]x[/tex] is not a factor of 24. So, this option is incorrect.

In option E, 2 is a factor of [tex]44y[/tex] but [tex]x[/tex] is not a factor of [tex]44y[/tex]. So, this option is incorrect.

It means the correct value for the given blank is either [tex]4xy[/tex] or [tex]12x[/tex].

Therefore, the correct options are B and C.

Answers

Answer:

A

Step-by-step explanation:

You divide the diameter by 2 to get radius. So 5÷2=2.5

So then you multiply 2.5 by pi aka 3.14 so 2.5x3.14=7.85 So we rounds 7.85 to 7.9

Answer:

B. 15.7

Step-by-step explanation:

Circumference= 2×π×r

2×3.14×2.5 (half of 5 is 2.5)

you have 11 art projects that weigh 24 pounds. If you give you mom 7 of your art projects, how much would her box weigh?

Answers

The weight for mom's boxes is obtained as 41.41 pounds.

What is weight?

Weight gauges how much gravity is pulling on a body.

The weight formula is provided by -

w = mg

Since weight is a force, it has the same SI unit as a force, which is the Newton (N).

Use a proportion to solve this problem.

Since the weight of the art projects is directly proportional to the number of art projects, we can set up the following proportion -

weight of 11 art projects / 11 = total weight / 24

Solving for the total weight -

total weight = (weight of 11 art projects / 11) x 24

total weight = 2.18 x 24

total weight = 52.32 pounds

So the total weight of the 11 art projects is 24 pounds, and if mom gets 7 of them, 4 art projects will be left weighing a total of -

weight of 4 art projects = (weight of 11 art projects - weight of 7 art projects)

weight of 4 art projects = (24 - (7/11) x 24)

weight of 4 art projects = 10.91 pounds

So, mom would be receiving 7 art projects weighing a total of -

weight of 7 art projects = (total weight - weight of 4 art projects)

weight of 7 art projects = (52.32 - 10.91)

weight of 7 art projects = 41.41 pounds

Therefore, mom's box would weigh 41.41 pounds.

Mark is six years older than his brother Sam. The sum of their ages is 30. Let 'a' be Sam's age.

Answers

Answer:

a = 12 years

Step-by-step explanation:

Mark is 6 years older than his brother Sam. Now, we are asked to represent Sam’s age by a. This means that if Sam is a years old, Mark is (a + 6) years old.

The sum of their ages is 30, this means that when we add their ages together, we get the sum of thirty.

Mathematically this means a + a + 6 = 30

2a + 6 = 30

This is the equation needed to get a. To get a , we proceed to solve the equation to completion.

2a = 30 - 6

2a = 24

a = 24/2

a = 12

There are 240 girls at the park. There are 360 more boys than girls at the park.How many boys are at the park?

Answers

Answer:

600 boys

Step-by-step explanation:

To find how many boys are at the park, add 360 to 240:

240 + 360

= 600

So, there are 600 boys at the park

Answer:

There are 600 boys at the park.

Step-by-step explanation:

The information we know is that there are already 240 girls at the park, and we also know that there are 360 more boys than girls. So to find out how many boys there are we must add the two values together, 240 and 360.

240 + 360 = 600

So that means there are 600 boys at the park.

The formula F=1.8C+32 can be used to convert temperature units. F is degrees Fahrenheit, and C is degrees Celsius.

Answers

Answer:

-40 °F = -40 °C

Step-by-step explanation:

The formula F = 1.8C + 32 gives the temperature in degrees Fahrenheit (F) for a given temperature in degrees Celsius (C). There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius. Complete the equation you can solve to find that temperature and then use it to find the temperature. Use the variable C to represent the number of degrees Celsius where degrees Fahrenheit and degrees Celsius are the same. The equation is . The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is °C.

F = 1.8 C + 32 (1)

There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius

Then,

F = C (2)

Substitute (2) into (1)

F = 1.8 C + 32 (1)

C = 1.8C + 32

Subtract 1.8C from each side

C – 1.8 C = 32

-0.8C = 32

Divide both sides by -0.8

C = 32 / -0.8

C = -40

Substitute C = -40 into (1)

F = 1.8C + 32 (1)

F = 1.8(-40) + 32

F = -72 + 32

F = -40

Therefore,

The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is -40

That is,

-40 °F = -40 °C
