Answer:

The probability of picking a purple marble and spinning green is [tex]\frac{3}{28}[/tex].

Step-by-step explanation:

Since there are 7 marbles and 8 possible tiles to spin, the total amount of possible outcomes are 56. Out of the 56 different outcomes, 6 of them meet the requirement of picking a purple marble and spinning green, so the fraction to represent the situation is [tex]\frac{6}{56}[/tex] or [tex]\frac{3}{28}[/tex].

At the beginning of 2007, the population of a certain state was 55.4% rural and 44.6% urban. Based on past trends, it is expected that 15% of the population currently residing in the rural areas will move into the urban areas, while 21% of the population currently residing in the urban areas will move into the rural areas in the next decade. What was the population distribution in that state at the beginning of 2017

Answers

Answer:

New Rural Urban distribution = 56.4 , 43.4

Step-by-step explanation:

Let the total population be = 100

The rural urban distribution = 55.4% & 44.6% of 100 = 55.4 & 44.6 respectively

Given , 15% of rural population shifts to urban. So, 15% of 55.4 ie = 8.31 shift from rural to urban.

Also, 21% of urban population shifts to rural. So, 21% of 44.6 , ie = 9.36 shift from urban to rural.

So, New rural population = old rural - rural to urban shift + urban to rural shift  = 55.4 - 8.31 + 9.36 = 56.39 ≈ 56.4

New urban population = old urban - urban to rural shift + rural to urban shift = 44.6 - 9.36 + 8.31 = 43.55 ≈ 43.4

So, the new distribution is =  56.4 , 43.4

Answers

Answer:

A

Step-by-step explanation:

It is A. The problem asks for the interval when the marlin's height is always increasing. Therefore, you want to look at the left half of the parabola, as the line is going into the peak. The right half is declining. The peak is at around 2 (on the x-axis), so you know that the ending interval number has to be 2. The marlin's height begins to go up starting at 0, so the interval is 0 <= x <= 2. Any number past two is a declining height, and the increase starts at 0.

1. 20% of 150 is what number?

Answers

Answer:

How do I graph -1, -4?

Answers

Answer:

Start at the origin and go to the left by one and go down by 4

Step-by-step explanation:

The x coordinate relates to the horizontal axis and the y axis refers to the vertical axis.

Before we start graphing we must always begin at the origin (0,0)

Since the x value is -1 we have to move left by 1 on the x axis

We would move to the left one value because negative is on the left side

For the y value, we would have to move 4 down on the y axis because this number is also negative.

So your graph should look like this

Solve the equation below. you must show all your work, and have the correct answer.

9x + 10 = 12x – 11

Answers

Answer:

x=7

Step-by-step explanation:

You need to bring 9x to the right side and bring '-ll' to the left side so it will be 11+10 = 12x-9x. Then you calculate 11+10, which is 21, then you subtract 12x to 9x. Then it will be 21 = 3x. Lastly, you divide 3 on both sides of the equation and get x to be 7!

Answer:

x=7

Step-by-step explanation:

9x+10=12x-11

-9x. -9x. subtract 9x from both sides

10 = 3x-11

+11 +11. add 11 to both sides

21 =3x

divide by 3x (21 ÷3=7) therefore x=7

A toy machine has equal numbers of red, white, and blue foam balls which it releases at random. Ross wonders which color ball will be released next. Select the description of how you can use a standard number cube to model and predict this situation.

A.Let multiples of 2 represent red, let multiples of 3 represent white, and let the remaining numbers represent blue. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability.

B.Since "red" has three letters and "one," "two," and "six" all have 3 letters, let these represent red. Since "blue" has 4 letters and "four" and "five" have four letters, let these represent blue. Since "white" has five letters and "three" has five letters, let this represent white. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability.

C.Let 1 and 2 represent red, let 3 and 4 represent white, and let 5 and 6 represent blue. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability.

D.Let even numbers represent red, let odd numbers represent white, and let prime numbers represent blue. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability.

Answers

Answer:

Since there are three colors and a standard number cube has 6 sides, you can let the numbers 1 and 2 represent red, 3 and 4 represent white, and 5 and 6 represent blue. Then roll the number cube repeatedly, recording the results for each roll. After you have recorded a sufficient number of rolls, determine which color was rolled the most often.

RESULT

Let the numbers 1 and 2 represent red, 3 and 4 represent white, and 5 and 6 represent blue.

Option (C) predicts the probability of the above situation correctly is the correct answer.

What is probability?

Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.

For the given situation,

A toy machine has equal numbers of red, white, and blue foam balls which it releases at random.

Ross wonders which color ball will be released next.

A standard number cube is used to model and predict this situation.

A standard number cube has six faces namely 1,2,3,4,5,6.

There are three foam balls. If we assign two numbers for each foam, then we can able to predict the probability of next foam by rolling it for number of times.

Thus from the given options, Let 1 and 2 represent red, let 3 and 4 represent white, and let 5 and 6 represent blue. Toss the cube 50 times to determine the experimental probability for each color. Predict that the next ball will be the color with the greatest experimental probability. This option determines the above situation.

Hence we can conclude that option (C) predicts the probability of the above situation correctly is the correct answer.

Halla dos numeros enteros sabiendo que al sumarlos se obtiene (-9) y que el mayor de ellos menos 5 es igual al menor

Answers

Respuesta:

-7 y - 2

Explicación paso a paso:

Dejemos que los dos números = x y y

x = mayor

y = menor

x + y = - 9 - - - (1)

x - 5 = y - - - (2)

Ponga y = x - 5 en (1)

x + (x - 5) = - 9

x + x - 5 = - 9

2x - 5 = - 9

2x = - 9 + 5

2x = - 4

x = - 4/2

x = - 2

Ponga x = - 2 en y = x - 5

y = - 2 - 5

y = - 7
