Answer:

The required inequality is: 12 ≤ 3x < 21

Step-by-step explanation:

We are given: three times a number is greater than or equal to 12 and less than 21

We need to answer following questions:

1) The inequality translated in numerical form

Let number = x

12 ≤ 3x < 21

2) Your work solving the inequality

We need to find value of x. Divide the inequality by x

4 ≤ x < 7

3) The solution graphed on a number line

It is shown in figure attached.

4) The solution in set notation

The set notation is: Considering x belongs to natural numbers N

{∀ x|x∈N, 4 ≤ x < 7}

5) The solution in interval notation

The interval notation is: [4,7)

because we have 4 less than equal to x and x is less than 7

The description of the relationship between the real zero(s) and x-intercept(s) of the function should be option A.

Since it is given that

f(x) = 3x(x - 1)

x2(x+3)(x + 1)

Also, the function should be set out and equivalent to zero when x = 1

and, the graph should have an x-intercept of (1,0).

Therefore, the option A is correct.

Answer:

3/4

Step-by-step explanation:

The value of cos C x sin A is 3/2.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

AB = 1

AC = 2

BC = √3

Now,

∠B = 90°

∠A = 60°

∠C = 180 - (90 + 60) = 180 - 150 = 30°

cos C = cos 30° = √3 / 2

sin A = sin 60° = √3/2

Now,

Cos C x Sin A

= √3/2 x √3 / 2

= 3/2

Thus,

The value is 3/2.

We will use Rotational transformation.

A congruence transformation is getting a congruence or similar image after we do any types of the known transformation.

According to the given question

We are given two shapes and we must show that they are congruent using transformations.

We can show the given two shapes are congruent by Reflections, Rotations and Translations.

Here in the given question it is being said that the orientation of these two shapes is the same so we should use rotational transformations.

In rotational transformation we can rotate a figure in clockwise or in anti-clock wise direction. Rotational transformation can be of any degree but in general we rotate it by 90°, 180°, 270° or by 360°.

In rotational transformation object's side length their adjacent angles remain same.

If by doing some degrees of rotational transformation and the figure looks exactly as before it has then it has rotational symmetry for that value of degrees.

Answer:

12.

Step-by-step explanation:

The geometric mean of two numbers a and b is sqrt(ab).

Hence, sqrt(8 * 18) = sqrt (144) = 12.

Hope this helped!

The geometric mean of 8 and 18 is 12 which is calculated as the square root of their product, which is 12.

Given two numbers are:

First number = 8

Second number = 18.

To find the geometric mean of two numbers, multiply the numbers together and then take the square root of their product.

Step 1: Find of the two numbers.

Product P: [tex]8 \times 18 = 144[/tex]

Step 2: Find the square root of the product.

Geometric mean = [tex]\sqrt{P}[/tex]

Plugging the value of P gives:

Geometric mean = [tex]\sqrt{144}[/tex]

Take the square root of 144, gives:

Geometric mean = 12.

Therefore, the geometric mean of 8 and 18 is 12.

The geometric mean is often used to find the average growth rate or to compare quantities that vary exponentially.

In summary, the geometric mean of 8 and 18 is calculated as the square root of their product, which is 12.

Step-by-step explanation:

Given

[tex]t = 6.95p + 29.95[/tex]

[tex]Amount = 70[/tex]

Required

Determine the domain

First, we need to solve for p

Substitute 70 for t in [tex]t = 6.95p + 29.95[/tex]

[tex]70 = 6.95p + 29.95[/tex]

Collect Like Terms

[tex]6.95p = 70 - 29.95[/tex]

[tex]6.95p = 40.05[/tex]

Solve for p

[tex]p = 40.05/6.95[/tex]

[tex]p = 5.76[/tex]

[tex]4.302(20) - 3.293 = 82.747[/tex]

The mean value of the response variable is 82.747.

Linear Regression calculates the equation of the line that is the best fit for the given data points. Linear regression models a linear relationship between the input variable x and the output variable y.

Here, given regression line;

        y= 4.302x - 3.293    ...............(i)

Now, value of x is given; x = 20

Put the value of x in equation (i), we get

     y = 4.302 X 20 - 3.293

     y = 86.04 - 3.293

     y = 82.747

Thus, the mean value of the response variable is 82.747.

Answer: Im confused?

Step-by-step explanation:

Answer:

E[X] = 1

Var[X] = 1

Step-by-step explanation:

We are told that n people enter the restaurant and put their hats at the reception.

This means that there are n hats.

Also, we are told that eeach person gets a random hat back when going back after having dinner.

Thus, each person will pick a hat uniformly at random and will get a right hat back with the probability: 1/n.

The expectation is linear even though the random variables are dependent. Thus, the expected mean of the total number of persons who get their right hat back is: E[X] = n × 1/n = 1

Now, the variance in hat problem is given by;

Var[X] = E[X²] - E[X]²

This gives;

Var[X] = E[X²] - 1

Now, E[X²] is expressed as;

E[X²] = n(1/n) + n(n - 1)•(1/n)•(1/(n - 1))

E[X²] = 1 + 1

E[X²] = 2

Thus;

Var[X] = 2 - 1

Var[X] = 1

Answer: what you need to do is multiply 3 times 1 and add 2 to the sum that you get which would be 5/3 for the first one because you keep the same denominator! Just multiply the denominator the bottom number and add the numerator the top number to your sum that you got from multiplication! Do that for all of them and you should get an improver fraction!
