Answer:

[tex]n=126[/tex]

Step-by-step explanation:

Using the formula for the sum of the angles of an [tex]n[/tex]-sided polygon, the sum of the angles is [tex]180(n-2)[/tex] degrees.

An exterior angle is supplementary to the corresponding interior angle. Using the given angle measures, the sum of the angles is [tex]2(180-50)+127+135+173n=522+173n[/tex] degrees.

Equating these two results,

[tex]180(n-2)=522+173n \\ \\ 180n-360=522+173n \\ \\ 7n-360=362 \\ \\ 7n=882 \\ \\ n=126[/tex]

Answer:

n=126

Step-by-step explanation:

180(n−2)=522+173n

180n−360=522+173n

7n−360=362

7n=882

n=126

The distance between the points Q and R is 7.211 units.

In geometry, an ellipse is a two-dimensional shape, that is defined along its axes. An ellipse is formed when a cone is intersected by a plane at an angle with respect to its base. It has two focal points.

Given an equation of ellipse x²/8+y²/18 =1, a line 2y = 3x intersect the ellipse at points Q and R,

x²/8+y²/18 =1........ (i)

2y = 3x....... (ii)

Use eq 2 in 1, we get

x²/8+(3x/2)²/18 = 1

On solving,  we get,

x²/4 = 1

x = ±2

And,

(2y/3)²/8+y²/18 = 1

On solving, we get,

y = ±3

Therefore, we got, y1 = 3, y2 = -3, x1 = 2 and x2 = -2

Using the distance formula, D = √(x1-x2)²+(y2-y1)²

QR = √(-2-2)²+(-3-3)² =  7.211

|QR| = 7.211

Hence, The distance between the points Q and R is 7.211 units.

The solutions to the absolute functions |3x - 1| - |2x + 5 - (5 - x)| = 0,  |2(x + 1) - 4| - 4| = |2 - 2(2 - x)|, |(x - 2) / 4| - 1/3 = x and 1/2|x - 3| - 1 = |x - 3| + 2 are 1/6, 1, 2/15 and no solutions respectively

An absolute value function is a function in algebra where the variable is inside the absolute value bars. This function is also known as the modulus function and the most commonly used form of the absolute value function is f(x) = |x|, where x is a real number. Generally, we can represent the absolute value function as, f(x) = a |x - h| + k, where a represents how far the graph stretches vertically, h represents the horizontal shift and k represents the vertical shift from the graph of f(x) = |x|. If the value of 'a' is negative, the graph opens downwards and if it is positive, the graph opens upwards.

In the questions given;

Question 1

|3x - 1| - |2x + 5 - (5 - x)| = 0

1997 for age 65 or older

Bachelor's degree or higher: The yellow bar starts at 75% and ends at 100%

To find how much percent of people 65 or older had a bachelor's degree in 1997, you subtract...100-75 = 25%

College/associate degree: 75 - 54 = 21%

High school graduates: 54 - 22 = 32%

Less than a High school diploma: 22 - 0 = 22%

Total: 25+21+32+22 = 100%

2007 for age 65 or older

Bachelor's degree or higher: 100 - 69 = 31%

College/associate degree: 69 - 46 = 23%

Answer:

C)  I, III, IV, II

Step-by-step explanation:

Convert each number into a decimal:

[tex]\textsf{I.} \quad \dfrac{58}{67}=0.86567...[/tex]

[tex]\textsf{II.} \quad 0.58\%=\dfrac{0.58}{100}=0.0058[/tex]

[tex]\textsf{IV.} \quad 5.8\%=\dfrac{5.8}{100}=0.058[/tex]

Comparing the tenths of all the numbers, 8 is the biggest tenth, so 58/67 is the largest number.

The next biggest tenth is 5, so 58% is the next largest number.

The two remaining numbers have zero tenths, so compare their hundredths. 5 is the largest hundredth, so 5.8% is the next largest number.  Therefore, 0.58% is the smallest number.

Therefore, the given set of numbers in order from greatest to least is:

Answer:

c) I, III, IV, II

Step-by-step explanation:

Values of l, ll, lll & lV respectively,

After 598 years the population of the country will be 677 million

The exponential model of the population is

A = 371.4 e^ (0.0241×t)

Where A is the total population in t years

t is the number of years

The population of the country = 677 million

677 million = 677e^8

Therefore the exponential equation will be

6.77 × [tex]10^8[/tex] = 371.4e^(0.0241t)

e^(0.0241t) = 6.77 × [tex]10^8[/tex] / 371.4

Divide the terms

e^(0.0241t) = 1822832.526

0.0241t = ln(1822832.526)

t = ln(1822832.526) / 0.0241

Divide the terms

t = 598.17

t ≈ 598 years

Hence, after 598 years the population of the country will be 677 million

In accordance with Pythagorean theorem, no point is 4 units away from point M.

In this problem we find the coordinates of points A, B, C, whose coordinates are (- 4, 2), (2, 7) and (8, - 6), respectively, and the location of point M, whose coordinates are (- 4, - 6), all set on Cartesian plane. We need to determine if at least one of those three points (A, B, C) are four units away from point M. This can be checked by means of Pythagorean theorem:

AM = √[(- 4 - 2)² + [- 6 - (- 4)]²]

AM = √[(- 6)² + (- 2)²]

AM = 2√10 = √40

BM = √[(- 4 - 2)² + (- 6 - 7)²]

BM = √[(- 6)² + (- 13)²]

BM = √205

CM = √[(- 6 - 8)² + [- 4 - (- 6)]²]

CM = √[(- 14)² + 2²]

CM = 10√2 = √200

Step-by-step explanation:

Form of an exponential function is

[tex]y = a \times b {}^{x} [/tex]

where a is the initial value, and b is the rate of growth

We know that when x=2

[tex]100 = a \times b {}^{2} [/tex]

when x=4

[tex]2500 = a \times b {}^{4} [/tex]

If we divide these two quantities we would get

[tex]25 = b {}^{2} [/tex]

[tex]b = 5[/tex]

So our rate of common growth is 5,

so b=5

[tex]y = a \times 5 {}^{x} [/tex]

We need to find the initial value, this means we solve for a.

[tex]100 = a \times 5 {}^{2} [/tex]

[tex]100 = a \times 25[/tex]

[tex]4 = a[/tex]

The standard deviation of the sampling distribution of sample means using the given information is 1.8

What does the mathematical term "rounding" mean?

Rounding is a method for estimating a specific number in a situation. To determine how to round a number, look at the next digit in the appropriate position; if it is less than 5, round down, and if it is greater than 5, round up. The precise rounding of decimal figures is referred to as "rounding decimals."

What are the guidelines for rounding off decimal numbers?

To locate the rounding digit, look at its right side.

If the right-side numbers are less than 5, consider them to be equal to zero.

The digit on the right is increased by one and the other digits are treated as zero if the right-side digits are greater than or equal to 5.

The population standard deviation divided by the square root of the sample size, or n, gives the standard deviation of the sampling distribution of sample means, or x, for any given population. Therefore:

For the provided data, the sampling distribution's standard deviation of sample means is [tex]\frac{14}{\sqrt{64} }[/tex], or 1.8.

Factoring quadratics with the leading coefficient not equal to 1 is similar to factoring when it is equal to 1. Here, (after subtracting the right side), we are looking for factors of 5·6 = 30 that add to 17, the coefficient of the x-term.

The sums of these factor pairs are 31, 17, 13, 11. We see that the factor pair (2, 15) is the one we want, as its sum is 17.

Answer:

(5x + 2)(x + 4)

Step-by-step explanation:

So, we have the equation [tex]5x^2+22x+8[/tex] right?

To get the [tex]x^2[/tex] we are going to need 'something' x in the first x slots of our factor form, like this:

(?x ± ?)(?x ± ?)

5 is a prime number, so one of the x's will be a 5x, and the other one a 1x:

(5x ± z)(x ± q)

z * q must be 8, and 5 * q + z must be 22

2 * 4 is 8

Let's plug these values in:

(5x + 2)(x + 4)

Let's multiply this out:

[tex]5x^2+22x+8[/tex]

This matches with our original equation!

So, our answer is:
