Please Help. This Is A Solve For X Problem!

Answers

Answer 1

Answer:

3/10 = x or 0.3 = x

Step-by-step explanation:

2.1 /  x + 1 4/5 = 3 / 10x

1. first cross multiply and solve it normally:

3 (x + 1 4/5) = (2.1) 10x

3x + 5 2/5 = 21x

-3x               -3x

5 2/5 = 18x

3/10 = x or 0.3 = x

these questions are kind annoying to solve because of the fractions, so if you can, use a calculator to solve them! its much easier!

hope this helps!

Answer 2

Answer:

x = 3/10 = 0.3

Step-by-step explanation:

{(2.1)/(x+1 4/5)} = 3/10x

x + 1 4/5 = x + 5/5 + 4/5 = x + 9/5

then:

(2.1)/(x+9/5) = 3/10x

10x*2.1 = 3(x+9/5)

21x = 3x+ 27/5

21x - 3x = 27/5

18x = 27/5

90x/5 = 27/5

90x = 27

x = 27/90

x = 3/10 = 0.3

Now that you have described several mappings, consider a more general example. Suppose you are given two shapes and you must show that they are congruent using transformations. If the orientation of these two shapes is the same, which type(s) of transformations should you use to show that they are congruent? Why?

Answers

We will use Rotational transformation.

What is congruence 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.

How would you describe the relationship between the real zero(s) and x-intercept(s) of the function
f(x) =
3x(x - 1)
x2(x+3)(x + 1)
When you set the function equal to zero, the solution is x = 1; therefore, the graph has an x-intercept of (1,0).
O When you set the function equal to zero, the solutions are x = 0 or x = 1; therefore, the graph has x-intercepts at
(0, 0) and (1,0).
O When you substitute x = 0 into the function, there is no solution, therefore, the graph will not have any X-
intercepts.
Since there are asymptotes at x = -3, x = -1, and x = 0, the graph has no x-intercepts and therefore, no real
zeros.

Answers

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

Relationship between the real zero(s) and x-intercept(s) of the function:

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.

The total cost in dollars for Larry to have his birthday party at a local
Trampoline Park can be found using the function t = 6.95p + 29.95, where p is
the number of people who will attend the party. If Larry only has $70 to spend on
his party, which of the following could represent the domain of the function?

Answers

Answer:

[tex]0 \leq p < 6[/tex]

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]

This implies that Larry can not invite up to 6 people.

Hence, the domain can be represented as: [tex]0 \leq p < 6[/tex]

what is the geometric mean of 8 and 18

Answers

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.

Suppose a least squares regression line is given by y= 4.302x - 3.293. What is the mean value of the response variable if x = 20?

Answers

Answer:

i think this is the answer

Step-by-step explanation:

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

The mean value of the response variable is 82.747.

What is Regression line?

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: 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!

Answers

Answer:

3/4

Step-by-step explanation:

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

What is a triangle?

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.

(Hat Check problem). n people enter the restaurant and put their hats at the reception. Each person gets a random hat back when going back after having dinner. Find the expected value and variance of the number of people who get their right hat back.

Answers

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
