2.

from the question, this population is applicable to the the teenagers in the study within the age of 13 to 17 years who do not own a smartphone.

3. pew research conducted a sample survey and not a census to obtain their results. it would be illogical and not practical to conduct a census. A sample survey is better for this since it would cost less, save more time and also the members of the survey can easily be picked from the american teenage population.. a census would require data for the full population compared to sample survey which would only require a subgroup of the teenage population.

The pairings between the mathematical descriptions and their algebraic expressions are as follows:

1. The absolute value of twice a number increased by 11: |2x + 11|

2. The square root of the difference of the square of a number and 11: [tex]\sqrt{(x^2 - 11)}[/tex]

3. The quotient of two times a number and -11: -2x / 11

4. The sum of the square root of two times a number and 11: [tex]\sqrt{(2x) + 11}[/tex]

The pairings between the mathematical descriptions and their corresponding algebraic expressions:

1. The absolute value of twice a number increased by 11: |2x + 11|

  This expression represents the absolute value of the sum of twice a number (2x) and 11. The vertical bars indicate the absolute value operation, which ensures that the result is always positive or zero.

2. The square root of the difference of the square of a number and 11: [tex]\sqrt{(x^2 - 11)}[/tex]

  This expression represents the square root of the difference between the square of a number ([tex]x^2[/tex]) and 11. The square root function (√) returns the positive square root of the expression within the parentheses.

3. The quotient of two times a number and -11: -2x / 11

  This expression represents the division of -2x (twice a number multiplied by -1) by 11. Dividing by 11 results in a quotient that may be positive, negative, or zero.

4. The sum of the square root of two times a number and 11[tex]\sqrt{(2x) + 11}[/tex]

  This expression represents the sum of the square root of twice a number [tex]\sqrt{((2x))}[/tex] and 11. The square root function (√) calculates the positive square root of 2x, and then 11 is added to the result.

By matching the descriptions with their corresponding expressions, we can see that each mathematical description is accurately represented by the algebraic expression provided.

Answer:

55 feet

Step-by-step explanation:

5.5                                   4

                _            =        _

                H                    40

The height of the dinosaur is 52.5 ft.

We know that:

12 inches = 1 ft

So, 1 inch = 1/12 ft

or, 3 inches = 3/12 = 0.25 ft.

So the height of Amir is = 5 ft 3 inch = 5.25 ft.

Let the height of the dinosaur is = x.

So, the ratio is:

[tex]\frac{5.25}{x}=\frac{4}{40}\\x=5.25\cdot\frac{40}{4}\\x=52.5[/tex]

The solution to the inequality is x < -5.

To solve the inequality -2(5x + 1) > 48, we need to isolate the variable x. Let's simplify the equation step by step:

-2(5x + 1) > 48

Start by distributing -2 to the terms inside the parentheses:

-10x - 2 > 48

Next, isolate the variable by adding 2 to both sides of the inequality:

-10x - 2 + 2 > 48 + 2

-10x > 50

Now, divide both sides by -10, remembering to flip the direction of the inequality when dividing by a negative number:

(-10x) / (-10) < 50 / (-10)

x < -5

This means that any value of x that is less than -5 will satisfy the original inequality. To express the solution using an inequality symbol, we write x ∈ (-∞, -5). The symbol (-∞, -5) represents the interval of all real numbers less than -5, including -5 itself.

Step-by-step explanation:

If i had a graph and i was using gallons per hour i would put gallons on the bottom and hours on the side

Answer/Step-by-step explanation:

So, if there is line on the graph and we need to get its equation in slope-intercept for (y = mx+b where m is the slope and b is the y-intercept). First, we have to take two points that lie on that line. Then, we will use the slope formula (m = y2 - y1 / x2 - x1). Once we get the slope, we have to find the y-intercept aka the b - value in the equation. So, to find this we have to take one of the coordinate point (that lies on the graph and was used to find the slope) and the slope. When you get the b - value, you have to substitute that value and the slope value into the equation. This is how you can write an equation from a graph.

Ex. (2, 3), (4, 9)

m = 9 - 3 / 4 - 2

m = 6/2

m = 3        <--- This is the m value aka the slope

y = mx + b         (In this case, we will use the first point which is (2,3)).

3 = 3(2) + b

3 = 6 + b

b = -3

y = 3x -3

Answer: (-1,-4)

Step-by-step explanation:

The values of a and b using the factor theorem for the polynomial f(x), we set f(1) and f(-1) equal to zero. Solving the resulting system of equations, we find that a = 12 and b = -1.

To find the values of a and b using the factor theorem, we need to use the given factors (x - 1) and (x + 1) and the fact that they are roots of the polynomial f(x).
The factor theorem states that if (x - c) is a factor of a polynomial, then f(c) = 0. Therefore, we can set x = 1 and x = -1 in the polynomial f(x) to get two equations.
First, let's substitute x = 1 into f(x):
f(1) = (1)^3 + a(1)^2 + b(1) - 12
f(1) = 1 + a + b - 12
Next, let's substitute x = -1 into f(x):
f(-1) = (-1)^3 + a(-1)^2 + b(-1) - 12
f(-1) = -1 + a - b - 12
Since (x - 1) and (x + 1) are factors, f(1) and f(-1) must equal zero. Therefore, we can set the two equations equal to zero and solve for a and b:
1 + a + b - 12 = 0
-1 + a - b - 12 = 0
Rearraning the equations, we have:
a + b = 11
a - b = 13
Now, we can solve this system of equations. Adding the two equations, we get:
2a = 24
a = 12
Substituting the value of a into one of the equations, we find:
12 - b = 13
b = -1
Therefore, the values of a and b are 12 and -1 respectively.

X = 109

Step-by-step explanation:

I = 5 – 2 (180) = 540  

100 + 102 + 108 + 121 = 431

540 – 431 = 109

X= 109

The value of the angle x will be 109 degrees.

A polygon is a closed polygonal chain made up of a finite number of straight-line segments that are joined to form a planar figure in a geometry or polygonal circuit. A polygon is a region that is bounded by a bounding circuit, a bounding plane, or both.

Given that an irregular pentagon with five different measured angles and five unequal sides. The angles of the pentagon are x degrees, 121 degrees, 108 degrees, 102 degrees, and 100 degrees.

The value of the angle x will be calculated as below:-

100 + 102 + 108 + 121 + x = 540

x = 540 – 431

x= 109

Therefore, the value of the angle x will be 109 degrees.
