How can you determine
a representative sample of a population?

Answer:

Step-by-step explanation:

If we multiply the first equation by 3 we get the same left sides in both equations:

3x - 18y = 12  

3x - 18y = 4

To make system with an infinite number of solutions we need to make the left sides the same as well.

The required resulting equation that gives infinite solution will be x-6y= 3 and 3x-18y= 12

System of equations can have difference kinds of solutions ranging from no solution, infinite number of solutions and real solutions.

For the system of equation that has infinite number of solutions, the two equations must be equal.

Given the system of equations

x-6y=4,

3x-18y=4

For the equation to have infinite number of solutions, we need to multiply the constant in equation 2 by 3 to have 4(3) = 12

Hence the required resulting equation that gives infinite solution will be x-6y= 3 and 3x-18y= 12

the ans is in the picture with the steps  

(hope it helps can i plz have brainlist :D hehe)

Step-by-step explanation:

Given:

The table of values.

v and x are in direct proportion.

To find:

The formula connecting v and x.

Solution:

(a)

v and x are in direct proportion.

[tex]v\propto x[/tex]

[tex]v=kx[/tex]            ...(i)

Where, k is the constant of proportionality.

Putting v=13.6 and x=32.64, we get

[tex]13.6=k(32.64)[/tex]

[tex]\dfrac{13.6}{32.64}=k[/tex]

[tex]\dfrac{5}{12}=k[/tex]

Putting the value of k in (i), we get

[tex]v=\dfrac{5}{12}x[/tex]

Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].

(b)

Putting v=n and x=8.16, we get

[tex]n=\dfrac{5}{12}(8.16)[/tex]

[tex]n=3.4[/tex]

Therefore, the value of n is 3.4.

Answer:

4 hours

Step-by-step explanation:

you take 42-10 because you take the total you made minus the $10 you chare to go to the house

then you take 32 divided by 8 for each hour spent

= 4 hours spent raking

If he earned $42 he spent 4 hours raking the leaves

During a fall he charges $10 to go to a house and rake the leaves and an additional $8 for every hour that he rakes the yard.

Therefore, the equation can be represented as follows;

where

x = number of hours

y = total charges

Therefore, If he earn $42 the number of hours worked can be calculated as follows:

8x = 42 - 10

8x = 32

x = 32 / 8

x = 4

Therefore, he works 4 hours to earn a total of $42

B. Engine Repair is more likely to be paid for with a credit card. Option B is correct

It is to be determined Which of these purchases is more likely to be paid for with a credit card
Parking fee  B. Engine repair  C. Soda   D. Lotto ticket

A credit card is a kind of credit service, delivered by banks that permit customers to borrow money within a pre-approved credit limit. It allows customers to make purchase transactions on goods and services.

Since option A, C and D can be omitted because, on parking fee, lotto ticket and soda spending through credit card can be possible but more likely because the spending on these items are very less and service provider do not intentionally accept the credit card
But engine repair is most likely to be paid from the credit card, because the liquidity in the business is very much high comparatively.

Thus, B. Engine Repair is more likely to be paid for with a credit card. Option B is correct

v^2 - 16

This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.

The square root of v^2 = v

The square root of 16 = 4

You get (v + 4)(v - 4)

Let's see what happens when you expand it.

Look what happens when you add these 4 terms together.

is what is left. The two middle terms cancel out.

Two

This one is a perfect square

w^2 + 16w + 64

(w + 8)(w + 8)

Notice both factors are the same. You might wonder how I new that.

w^2 is a perfect square so take the square root.  ....   v      

64 is a perfect square so take the square root    .....    8

Now you have to work backwards to see if it is right.

Adding you get w^2 + 16w + 64 which is what you started with.
