Answer:

Pr = 6.67\%

Step-by-step explanation:

Given

n = 10 i.e. 10 people

Required

Probability of being next to each other

First, we calculate the total possible arrangements (without any restriction)

Total = n!

Total = 10!

If the three are to be next to each other,

First, we arrange the three

r_1 = 3!

Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)

The arrangement is:

r_2 =8!

So, the total arrangement, when they have to be next to one another is:

r = r_1 * r_2

r = 3! * 8!

The probability is:

Pr = \frac{r}{n}

Pr = \frac{3! * 8!}{10!}

Expand

Pr = \frac{3*2*1 * 8!}{10*9*8!}

Pr = \frac{3*2*1}{10*9}

Pr = \frac{6}{90}

Pr = 0.0667

Express as percentage

Pr = 0.0667 * 100\%

Pr = 6.67\%

Write the equation for the following relation. Include all of your work in your final answer. Submit your solution.
ella [17]

Answer:

y=x^3

Step-by-step explanation:

The given relation is Q = {(x, y): (2, 8), (3, 27), (4, 64), (5, 125), . . .}

We can quickly recognize a pattern to write the equation of the given relation.

We can observe the following pattern among the x and y coordintaes.

8=2^3

27=3^3

64=4^3

125=5^3

We can see that the base of the powers on the right are the x-values of the relation and the values on the left are the y-values.

Hence, for any ordered pair (x,y), the equation is

y=x^3

The ratio of sides of 2 similar cubes is 3:4. Larger cube has a volume of 1728 cubic meters . What is the volume of the smaller
Tanya [424]

Answer:

729m³

Step-by-step explanation:

To find the length of one side find the cube root of 1728m³

³√1728=12metres

To find the length of the smaller cube

ratio 3:4.

4/7=12m

3/7=?

<u>3</u><u>/</u><u>7</u><u>×</u><u>1</u><u>2</u><u> </u>= 3/7×12×7/4

<u> </u><u> </u><u> </u>4/7

=9metres

To find volume of the small cube

volume=9×9×9

=729m³

Which of the equations below could be the equation of this parabola? ​
Marrrta [24]

Answer:

The answer to your question is letter C.

Step-by-step explanation:

A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.

B. The same as letter A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.

C. This option is correct, is the equation of a vertical parabola and the negative indicates that it opens downward, as in the graph.

D. This option is incorrect because the equation is of a vertical parabola that opens upward.
