Martha rolls a 6 sided number cube two times.
What is the probability that she will roll a prime number both times.

Answers

Answer:

25% chance

Step-by-step explanation:

There are 3 prime numbers on a 6-sided die so that means there is a 1/2 chance you roll a prime number. In order to calculate the probability of 2 or more events you multiply their probability which would be

1/2 * 1/2 = 1/4

So the chance of rolling a prime number on both rolls is a 1/4 chance or a 25% chance

The probability that she will roll a prime number both times is 0.25.

What is the probability?

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

Martha rolls a 6 sided number cube two times.

And the prime numbers in the cubes are {2, 3, 5}.

The probability that she will roll a prime number both times,

= 3/6 x 3/6

= 1/2 x 1/2

= 1/4

= 0.25

Therefore, 0.25 is the probability.

Una moto A consume 8,2 litros de gasolina por cada 100km y otra moto B 8,9 litros de gasolina también por cada 100km. Calcula la gasolina que consume una moto en 1 km

Answers

Respuesta:

Motocicleta A = 0.082 litros por km

Motocicleta B = 0.089 litros por km

Explicación paso a paso:

Dado :

Consumo de gasolina de la motocicleta A y la motocicleta B por 100 km

Motocicleta A = 8.2 litros

Motocicleta B = 8,9 litros

Consumo por kilómetro:

Litros consumidos por 100 km / 100 km

Motocicleta A:

8.2 / 100 km

= 0,082 litros por km

Motocicleta B:

8,9 / 100 km

= 0,089 litros por km

The coordinates of point are (7, 4). Point is a reflection of point across the x-axis. In which quadrant will point W be located

Answers

Answer:

Point W will be located on the bottom right quadrant.

Step-by-step explanation:

The x variable becomes negative when reflected across the x-axis.

Answer:

The reflected point will be on the 4th qudrant.

Step-by-step explanation:

So, lets remember what each qudrant is. The first one is (+, +).

The secodn one is (+, -)

The third one is (-,+)

And the fourth one is (-,-)

So looking at this, we instantly know that the orginal point is on qudrant 1. Since our number is +7, +4.

Now we have to flip around the x axis. Well, to the left of the quadrant 1 is qudrant 2. To the bottom of qudrant 1 is qudrant 4. We clearly cannot go to the top or right since there arent any more quadrants, and the qudrant 3 is not accesable with our x and y values.

Remember. we arent going left, since that would be crossing the y axis. This means we have to go down, to the bottom.

What is below qudrrant 1? As I said above, that would be quadrant 4.

Answer:

Quadrant 4

For Greta's birthday party, her parents ordered 6 pizzas. If they cut the pizzas into sixths, how many pieces will there be? Choose the model that matches this problem.

Answers

Options aren't avaible

Answer:

(1 ÷ 1/6) * 6

36 pieces of pizza

Step-by-step explanation:

Given that :

Number of pizzas ordered = 6

Divisions per pizza = 1/6 ;

Hence, 1 full pizza is divided into 1 ÷ 1/6 = 1 * 6/1 = 6 pieces

6 * 1/6(1)

The total pieces of pizzas equals :

6 pieces per pizza * number of pizzas

6 * 6

= 36 pieces of pizza

Use your understandinh of rational functiosn to answer the followinh wuestions about the relationship of concert profit

Answers

Question:

Use your understanding of rational functions to answer the following question about the relationship of concert profit P(x)=-25x^2+875x-4750 to concert operating expenses c(x)=4750-125x.

Write an algebraic rule for the function T(x), which gives the ratio of profit to operating expenses, that is, the number of dollars earned for every dollar spent by the concert promoters.

Answer:

[tex]T(x) = \frac{x^2-35x+190}{5x-190}[/tex]

Step-by-step explanation:

Given

[tex]P(x)=-25x^2+875x-4750[/tex] --- concert profit

[tex]c(x)=4750-125x.[/tex] --- concert operating exercise

Solving (a): An expression for T(x)

T(x) is the ratio of P(x) to c(x)

So:

[tex]T(x) = \frac{P(x)}{c(x)}[/tex]

[tex]T(x) = \frac{-25x^2+875x-4750}{4750-125x}[/tex]

Factorize

[tex]T(x) = \frac{-25(x^2-35x+190)}{-25(-190+5x)}[/tex]

[tex]T(x) = \frac{x^2-35x+190}{-190+5x}[/tex]

Rewrite as:

[tex]T(x) = \frac{x^2-35x+190}{5x-190}[/tex]

At a football game, a vender sold a combined total of 181 sodas and hot dogs. The number of hot dogs sold was 51 less than the number of sodas sold. Find the
number of sodas sold and the number of hot dogs sold.

Answers

Answer: Number of hot dogs sold = 65

number of soda sold = 116.

Step-by-step explanation:

Let the number of hot dogs sold be represented by x.

Since the number of hot dogs sold was 51 less than the number of sodas sold, then the number of soda sold will be: = x + 51

Since the addition of both hot dogs and soda equals 181, we can form this into an equation which will be:

= x + (x + 51) = 181

x + x + 51 = 181

2x + 51 = 181

2x = 181 - 51

2x = 130

x = 130/2

x = 65

Number of hot dogs sold = 65

Since number of soda sold equals:

= x + 51

= 65 + 51

= 116

Therefore, number of soda sold is 116.
