I need help... It's kinda confusing for me..

Answer:

First choice

Step-by-step explanation:

It passes through (4, 0) and (0, -4)

Slope = (0 - (-4))/(4 - 0) = 4/4 = 1

so y - 0 = 1*(x - 4)

x - y = 4

8x - 8y = 32

The pairs of shoes is an illustration of the point estimate of the population mean.

The teenagers have 30 pairs of shoes

The question is incomplete, as the dataset to determine the number of shoes is not given.

To answer the question, I will use the following dataset

50 26 26 31 57 19 24 22 23 38 13 50 13 34 23 30 49 13 15 51

The sample mean is an estimate of the population mean.

The sample mean is calculated as:

[tex]\bar x = \frac{\sum x}{n}[/tex]

So, we have:

[tex]\bar x = \frac{50 +26+ 26+ 31+ 57 +19 +24 +22+ 23 +38 +13 +50 +13 +34+ 23+ 30 +49 +13 +15+ 51}{20}[/tex]

Evaluate the sum

[tex]\bar x = \frac{607}{20}[/tex]

Evaluate the quotient

[tex]\bar x = 30.35[/tex]

Approximate

[tex]\bar x = 30[/tex]

Using the assumed values, the teenagers have 30 pairs of shoes

The fraction of his lotto earnings that is remaining is 7/20.

A fraction is a portion of a whole or, more broadly, a set of equal pieces.

Let the total amount that the man won in the lotto jackpot is x.

Now, he spent 2/5 of the jackpot on luxury cars and 1/4 on buying a house, therefore, the total spending he will do is,

[tex]\dfrac{2x}{5}+\dfrac{x}{4}[/tex]

Now, the fraction of his lotto earnings that is remaining can be written as,

[tex]x-\dfrac{2x}{5}+\dfrac{x}{4}\\\\\\=\dfrac{x}{1}-\dfrac{2x}{5}-\dfrac{x}{4}\\\\\\=\dfrac{x \times 20}{1 \times 20}-\dfrac{2x \times 4}{5 \times 4}-\dfrac{x\times 5}{4\times 5}\\\\\\=\dfrac{20x-8x-5x}{20}\\\\=\dfrac{7x}{20}[/tex]

Hence, the fraction of his lotto earnings that is remaining is 7/20.

I hope this helps you.

Step-by-step explanation:

Assets are the economic resources belonging to a business. Assets could be money in a cash register or bank account, or items such as property, fixtures and furniture, equipment, motor vehicles, and stock or goods for resale. An important asset in businesses which sell goods or services on credit is money owed to the enterprise by customers. This asset is known as debtors.

Capital is the value of the investment in the business by the owner(s). It is that part of the business that belongs to the owner; hence it is often described as the owner’s interest.

Liabilities are the debts owed by the firm. The main types of liabilities are creditors (money owed by the business to suppliers of goods and services), bank overdrafts and bank loans.

Using the permutation formula, as the order is important, it is found that 2520 distinct passwords can be made.

The order is important as abcde is a different password than edcba, hence the permutation formula is used.

The number of possible permutations of x elements from a set of n elements is given by:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

In this problem, 5 letters are chosen from a set of 7, hence:

Answer:

  132°

Step-by-step explanation:

An inscribed angle is half the measure of the arc it subtends. This means arc CB is twice the measure of inscribed angle CAB, so ...

  arc CB = 2×∠CAB = 2×40° = 80°

Arc AC is twice the measure of inscribed angle ABC, so ...

  arc AC = 2×∠ABC = 2×26° = 52°

The measure of central angle AOB is the same as the measure of arc AB.

  x = ∠AOB = arcs AC +arc CB = 52° +80°

  x = 132°

The amount the customers pay is an illustration of a piecewise functions

The equations of the piecewise functions are: [tex]y = \left[\begin{array}{cc}5x&0 < x \le 5\\4x&x > 5\end{array}\right[/tex]

For the first function, we have the following points.

(x,y) = (0,0) and (4,20) for 0 < x <= 5

Since the line passes through the origin, the equation of the line would be:

[tex]y = \frac{y_1}{x_1} * x[/tex]

So, we have:

[tex]y = \frac{20}{4} * x[/tex]

[tex]y = 5x[/tex]   0 < x <= 5

For the second function, we have the following points

(x,y) = (8,32) and (9,36) for x > 5

The equation of the line would be:

[tex]y = \frac{y_1-y_2}{x_1-x_2} * (x - x_1) + y_1[/tex]

So, we have:

[tex]y = \frac{36-32}{9-8} * (x - 8) + 32[/tex]

[tex]y = 4(x - 8) + 32[/tex]

[tex]y = 4x - 32 + 32[/tex]

[tex]y = 4x[/tex]    x > 5

Hence, the equations of the piecewise functions are:

[tex]y = \left[\begin{array}{cc}5x&0 < x \le 5\\4x&x > 5\end{array}\right[/tex]

Answer:

y=23x+204

Step-by-step explanation:

The Slope Intercept Form of the Equation of a Line is y=mx+c

where m is the Slope and c is the y-intercept

so for our problem m=Slope = 23

so the Equation will be y=23x+c

Now to find c just substitute by the given Point

-3=23*-9+c

c=204

so the Equation will be

y=23x+204

Answer: 7:3 and 28:12

Step-by-step explanation:

The equivalent form of the given ratio is 7 : 3. The correct answer is option (b).

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

The given ratio is 14 : 6.

A ratio of two numbers a and b can be written in the form of fraction as,

a : b = a/b

Thus, the given ratio can be simplified as,

14 : 6 = 14/6

         = 7/3

Again it can be converted into the ratio as,

7/3 = 7 : 3

Hence, the equivalent ratio of the given ratio is 7 : 3.

Step-by-step explanation:

We use the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], and substitute the points (0,8) and (2,4). This gives

[tex]\frac{4-8}{2-0}=\frac{-4}{2}=-2[/tex]

as the slope.

Hello.

Since we have two points, and we are asked to find the slope of the line, let's use the slope formula:

[tex]\mathrm{m=\displaystyle\frac{y2-y1}{x2-x1}}[/tex]

Where

m is the slope

y2 is the y-coordinate of the second point

y1 is the y-coordinate of the first point

x2 is the x-coordinate of the second point

x1 is the x-coordinate of the first point

In this case, m is unknown, y2 = 4, y1 = 8, x2=2, x1=0

Plug in the values:

[tex]\displaystyle\frac{4-8}{2-0}[/tex]

[tex]\displaystyle\frac{-4}{2} =-2[/tex]

Therefore, the slope is -2.

I hope it helps!

Have a nice day!
