Indicating whether the variable is relevant to the questions, and Identifying the variable as either categorical or quantitative.

Rather than straightforward explanations. Anything may be measured using it. It can also do mathematical calculations, which is essential for data analysis.

To completely understand all of the facets of quantitative data, statistical analysis—the discipline of obtaining, analysing, and presenting enormous volumes of data to uncover patterns and trends—is used. This calls for quantitative analysis employing a wide variety of data.

Categorical data is data that may be arranged into groups or categories using names or labels.

The approach is based on algorithms that assess each component of a data collection individually, compare them to other individual data sets, and look for particular similarities.

Answer:

Step-by-step explanation:

Finding an equation of a line can be condensed into 2 easy steps.  Step one is to establish the basic form of the equation, including it's slope.  

1)  Lets use y=mx + b as the basic form, where m is the slope and b is the y-intercept (the value of y when x is zero).  We are told the line is parallel to y = 3x - 1, which is a line with a slope (m) of 3.  Parallel lines have the same slope, so our kline will also have a slope of 3, bringing us to:

   y = 3x + b.

2)  The second step is finding the value of b.  We are told the line must go through point (1,5), so we need a value of b that will shift the line to (1,5).  Easy:  just enter this point in the equation we have so far:  y = 3x + b:

y = 3x + b

5 = 3*(1) + b for point (1,5)

b = 2

The equation becomes y = 3x + 2

See the attached graph.  [Extra credit]

The lines are parallel, and the y-intercept for the second line (b) is (0,2).

Answer:

angle 1 is 28 degrees  angle 2 is 62 degrees

DONT FORGET TO PUT THE DEGREES SIGN

Step-by-step explanation:

since it is a right angle, angle 1+ angle 2 is 90 degrees.

So,

2x+(x+48)=90

3x=90-48

3x=42

x=14

angle 1=28   angle 2=62

The volumes of the structure are:

1. (8 + x)(16 + 2x)(6 + 3x) + 12(8 + x)(3 + x)

2. (8 + x)(16 + 2x)(3 + x) + 12(8 + x)(3 + x) + 12(6 + 3x)(3 + x)

3. (8 + x)(16 + 2x)(6 + 3x) - 2[12(8 + x)(3 + x)]

A polynomial expression is an algebraic expression consisting of variables and coefficients, and involving only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

Examples include 2x^3 - 5x^2 + 3x + 1 and 4y^2 + 7y - 2.

1.We can divide the structure into two rectangular prisms, as shown in the sketch. The dimensions of the first prism are (8 + x)(16 + 2x)(6 + 3x), while the dimensions of the second prism are 12(8 + x)(3 + x). To find the total volume, we can add the volumes of the two prisms:

(8 + x)(16 + 2x)(6 + 3x) + 12(8 + x)(3 + x)

2.We can also divide the structure into three rectangular prisms, as shown in the sketch. The dimensions of the first prism are (8 + x)(16 + 2x)(3 + x), the dimensions of the second prism are 12(8 + x)(3 + x), and the dimensions of the third prism are 12(6 + 3x)(3 + x). To find the total volume, we can add the volumes of the three prisms:

(8 + x)(16 + 2x)(3 + x) + 12(8 + x)(3 + x) + 12(6 + 3x)(3 + x)

3.We can view the structure as one large rectangular prism with two smaller rectangular prisms removed, as shown in the sketch. The dimensions of the large prism are (8 + x)(16 + 2x)(6 + 3x), while the dimensions of each small prism are 12(8 + x)(3 + x). To find the total volume, we can subtract the volumes of the two small prisms from the volume of the large prism:

(8 + x)(16 + 2x)(6 + 3x) - 2[12(8 + x)(3 + x)]

We can find the two linear equations by using the point-slope form of a line: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

For the first equation:

Using the first point (-2, 8), we have m = (y2 - y1) / (x2 - x1) = (-3 - 8) / (-2 - (-2)) = -11/0, which is undefined. This means the first line is a vertical line.

The equation can then be written as x = -2, since the x-coordinate is constant.

For the second equation:

Using the second point (-1, 4), we have m = (y2 - y1) / (x2 - x1) = (-2 - 4) / (-1 - (-2)) = -2.

The equation can then be written as y - 4 = -2(x + 1), or y = -2x - 2.

Thus, the system of linear equations is:

x = -2

y = -2x - 2

Written in standard form:

x + 0y = -2

-2x + y = -2

Using trigonometry formulas, the value of tan(x-y) = -16/63

In the field of mathematics known as trigonometry, correlations between angles and length ratios are studied. Trigonometry has a wide variety of identities. In order to simplify an expression, identify a more practical version of an expression, or solve an equation, trigonometric identities are frequently employed to rewrite trigonometrical expressions.

Given

cot y = 4/3

1/tan y = 4/3

Cross multiply

tan y = 3/4

Also since csc x = 13/5

1/sin x = 13/5

sin x = 5/13

Since sin x = opp/hyp

opp = 5

hyp = 13

Get the adjacent

hyp² = opp²+adj²

13² = 5²+adj²

adj² = 13² - 5²

adj² = 169 - 25

adj² = 144

adj = 12

cos x = adj/hyp

cos x = 12/13

tan x = sin x/ cos x

tan x = (5/13)/(12/13)

tan x = 5/13 * 13/12

tan x = 5/12

tan(x-y) = tan x - tan y/1 + tan x * tan y

tan(x-y) = (5/12 - 3/4) / 1 + (5/12) (3/4)

tan(x-y) = (5-9/12) / 1 + 5/16

tan(x-y) = -4/12/(21/16)

tan(x-y) = -1/3 * 16/21

tan(x-y) = -16/63

the value of tan(x-y) is -16/63

Answer:

  ㏒₅₄168 = (1+ab)/(8a-5ab)

Step-by-step explanation:

You want ㏒₅₄168 written in terms of a and b, where ...

The rules of logarithms are relevant here:

  [tex]\log_b(a)=\dfrac{\log(a)}{\log(b)}\\\\\log(ab)=\log(a)+\log(b)[/tex]

In order to simplify the writing in what follows, we want to define ...

Now, we can write the equations ...

  a = log(12)/log(7) = (2p+q)/r . . . . . . . . . [eq1]

  b = log(24)/log(12) = (3p+q)/(2p+q) . . . [eq2]

Using these, we can solve for p and q:

  2p +q = ar . . . . . . . . . . . . . [eq3], from [eq1]

  (3 -2b)p +(1 -b)q = 0 . . . . . [eq4] from [eq2]

Using your favorite solution method for linear equations, you find ...

  p = ar(1 -b)/(2(1 -b) -(3 -2b)) = ar(1 -b)/(2 -2b -3 +2b) = ar(b -1)

  q = (-ar(3 -2b)/(-1) = ar(3 -2b)

Substituting these expressions into ...

  [tex]\log_{54}{168}=\dfrac{\log{(2^3\cdot3\cdot7)}}{\log{(2\cdot3^3)}}=\dfrac{3p+q+r}{p+3q}\\\\=\dfrac{3ar(b-1)+ar(3-2b)+r}{ar(b-1)+3ar(3-2b)}=\dfrac{3ab-3a+3a-2ab+1}{ab-a+9a-6ab}\\\\=\boxed{\log_{54}{168}=\dfrac{1+ab}{8a-5ab}}[/tex]

The age that she must work till she is qualified to receive Social Security benefits when she retires is: 56 years

Social Security benefits provide partial replacement income for retired beneficiaries and disabled persons, as well as their spouses, children and survivors.

To be eligible for Social Security benefits, you must be enrolled in the Social Security program and accumulate 40 credits while employed.

Benefits are based on your income history, year of birth, and age at which you began applying for Social Security.

If your spouse is unemployed or has not reached the required number of credits, you can receive benefits according to your spouse's work performance.

Benefits may likely be taxed based on the specific income and tax return status.

She will be required to earn a total of 40 credits in order to qualify to be able to receive social security benefits, due to the fact that she earns the maximum number of 4 credits per year, she therefore has to work for at least a minimum of ten years or until at least she is 56.

x = 4

-- All angles of a triangle add up to 180° --

-- the inverse of a trianglenis equal to its opposite angle of intersection--

1) build equation

180° = 20° + (4 + 6x) + (32x + 4)

2) solve

180-20 = 4 + 6x + 32x + 4

160 = 8 + 38x

152 = 38x

152/38 = x

x = 4

verify

180 = 20 + (4 + 6x) + (32x + 4)

180 = 20 + (28) + (132)

180 = 180 so x = 4

Answer:

18

Step-by-step explanation:

Because there are 12 more blue tiles than red, that means that we can write the equation 3x + 12 = 5x. By simplifying, the equation is boiled down to 12=2x. By dividing, we see that x=6. This means that we can multiply 3 by 6 to get 18 red tiles. To check our answer, we just multiply 6 by 5 to get 30, and the ratio 18:30 is equivalent to 3:5. Also, 30-18=12, so this must be correct.

Step-by-step explanation:

r = r1 - 5t, t is time in weeks, r is the number of copies rented, r1 how many people were renting at the start

we know on the 6 weeks passed and 4 copies were rented

4 = r1 - 5(6)

4 = r1 - 30; add 30 on both sides

34 = r1

r = 34 - 5t now plug t = 2 in for this function

r = 34 - 5(2)

r = 35 - 10
