Data collected at the same, or approximately the same point in time are  Cross- sectional data

In statistics and econometrics, cross-sectional data, or a cross section of a study population, is a type of data gathered by monitoring numerous subjects (such as individuals, firms, countries, or regions) at one point or throughout the course of time. It's also possible that the analysis disregards variations in time. Cross-sectional data analysis often entails contrasting the variations among pre-selected respondents.

For instance, if we wanted to determine the prevalence of obesity in a population, we could randomly select a sample of 1,000 people (also referred to as a cross section of that population), measure their height and weight, and then determine what proportion of that sample falls under the definition of obesity. With the use of this cross-sectional sample, we are able to get a current picture of that group. Be aware that based on a single cross-sectional sample, we cannot determine whether the prevalence of obesity is rising or falling; we can only describe the current proportion.

The solution is Option A.

The inequalities have one common solution

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equations be represented as A and B

The value of A is

( 1/2 )x + 8 ≤ 10   be equation (1)

-3x - 24 ≤ - 36   be equation (2)

On simplifying the equation (1) , we get

Subtracting 8 on both sides of the equation , we get

( 1/2 )x ≤ 2

Multiply by 2 on both sides of the equation , we get

x ≤ 4

And , on simplifying the equation (2) , we get

Adding 24 on both sides of the equation , we get

-3x ≤ -12

Multiply by -1 on both sides of the equation , we get

3x ≥ 12

Divide by 3 on both sides of the equation , we get

x ≥ 4

So , the common solution to the inequalities is x = 4

Answer:

b = 13

Step-by-step explanation:

21 = b + 8   Subtract 8 from both sides

21 - 8 = b + 8 - 8

13 = b

Answer: 13

Step-by-step explanation:

He bought two books for $21, and one of the books was $8. With this, we know that if we subtract 8 from 21, we can get "b", or the cost of the other book

21 = b + 8

-8        -8

13 = b

b = 13

There are two possible options for points and distances:

In this problem we need to determine the location of point M and distances between points A, M and B. This can be done by means of differences on number line and algebraic equations:

M - A = x² - x

M - (- 14) = x² - x

M + 14 = x² - x

M = x² - x - 14

B - M = 5 · x + 4

35 - M = 5 · x + 4

M = 31 - 5 · x

Then, we eliminate M and find the solutions to the resulting quadratic equation:

x² - x - 14 = 31 - 5 · x

x² + 4 · x - 45 = 0

(x + 9) · (x - 5) = 0

x = - 9 or x = 5

Finally, we determine the possible values for M based on the fact that M is between - 14 and 35:

x = - 9

M = 31 - 5 · x

M = 31 - 5 · (- 9)

M = 31 - 45

M = - 14

AM = - 14 - 14

AM = 0

MB = 35 - (- 14)

MB = 49

x = 5

M = 31 - 5 · x

M = 31 - 5 · 5

M = 31 - 25

M = 6

AM = 6 - (- 14)

AM = 20

MB = 35 - 6

MB = 29

The required values of x in the interval 0° ≤ x ≤ 360° are 146.1° and 326.1°, when the value of tan x is given.

The interval of angle is given as 0° ≤ x ≤ 360°.

The value of x for which tan x is given as, tan x = - 0. 6745.

We have tan negative in two of the four axes, they are second (90° - 180°) and fourth quadrants (270° - 360°).

So, tan x = - 0. 6745

x = tan⁻¹ (- 0. 6745) = -33.9

As periodicity of tan x is 180°, x = 180-33.9 = 146.1°

x = 360-33.9 = 326.1°

Thus, the required values of x in the interval 0° ≤ x ≤ 360° are 146.1° and 326.1°, when the value of tan x is given.

The angles in the quadrilateral are as follows:

g = 116 degrees

h = 64 degrees

A quadrilateral is a polygon with 4 sides. The sum of angles in a quadrilateral is 360 degrees.

Therefore, let's find the angles g and h in the quadrilateral. According to the diagram, the quadrilateral has opposite side parallel to each other.

Therefore, the diagram can be regarded as a parallelogram.

Hence, adjacent angles of the diagram are supplementary.

Supplementary angles add up to 180 degrees.

Therefore,

116 + h = 180

h = 180 - 116

h = 64 degrees.

Therefore,

Negative bases are not often used in logarithms because they produce complex results. For example, if the base is negative and the exponent is positive, the result will be a complex number.

Logarithms are generally used to solve equations or simplify complex problems. Having a negative base would complicate this process, as it would introduce complex numbers or even imaginary numbers into the equation. Consequently, it is not feasible to use negative bases with logarithms. Furthermore, if both the base and the exponent are negative, the result is undefined. This means that it is not possible to evaluate the expression. Therefore, for these reasons, it is usually not practical to use negative bases when working with logarithms.

The solution of the system of equation using elimination method is x = -2, y = -4

The elimination method is a method used to solve systems of linear equations. It involves manipulating the equations in such a way that one of the variables is eliminated, resulting in an equation in one variable that can be easily solved.

-2y = 2 - 3x --- (1)

-5y = 10 - 5x ---(2)

To eliminate y, multiply (1) by -5 and multiply (2) by -2. Then subtract the result. That is:

-5 × (-2y = 2 - 3x)   =>  10y = -10 + 15x

-2 ×(-5y = 10 - 5x)    => 10y = -20 + 10x

.......................................................................

                                      0 = 10 +5x

.........................................................................

0 = 10 +5x

5x = -10

x = -10/5

x = -2

put x = -2 in (1):

-2y = 2 - 3x

-2y = 2 -3(-2)

-2y = 2 + 6

-2y = 8

The possible values of x such that 33+x remains a positive integer in ascending order are 1,3,11 and 33.

An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.

Integer; ....-2, -1, 0, 1, 2, .....

Given the expression, 33+x

Now positive integers are whole numbers ( 1,2,3,...)

To 33/x be the whole number and x is also a positive integer.

33/1 = 33 (1,3 Positive integer)

33/3 = 11 (3,11 Positive integer)

33/11 = 3 (11,3 Positive integer)

33/33 = 1 (33,1 Positive integer)

The factorization of -25-15mn is -5(5+3mn)

Factorising is the reverse process of expanding brackets. To factorise an expression fully, means to put it in brackets by taking out the highest common factors. The simplest way of factorising is: Find the highest common factor of each of the terms in the expression.

For example 5( 3x+ 2y+ 4z) can be expanded into 15x + 10y + 20z and moreover 15x + 10y + 20z can be transformed by finding the factors between each terms, here the factor is 5; 5( 3x + 2y +4z)

Similarly to factorize -25-15mn we find the factor that is common to -25 and - 15 . The common factor is -5.

therefore factorizing -25-15mn we bring -5 out of -25 and -5

Percent of the total amount a per the given list price, documentation fee , registration fee and other payment paid by Charles is given by :

Option c. 16.70%

Cost of his old 2004 Dodge Neon = $6591

Sales tax = 6.88%

Dealer gives 80% trade in price on hos car

After tax selling price of the car

= 6,591 × (80/100) × [ 1 - (6.88/100) ]

= $4910.03

= $4,910

Vehicle registration amount = $1,089

List price of car = $21,450

Documentation fee = $124

Total cost of the car

= $21,450 + $1,089 + $124

= $22,663

Net amount Charles needs to pay

= $22,663 - $4,910

= $17,753

Monthly payment at the rate of 12.28% compounded monthly for 3 years

= 17753 [ 12.28%( 1+ 12.28%)^3 / [( 1+ 12.28%)^3 -1 ]

= $592

Total amount paid by Charles

= $592 × 36

= $21,312

Total interest paid by Charles

= $21,312 - $17,753

= $3,559

Percent of the total amount

= ( $3,559 / $21,312 ) × 100

= 16.699%
