Answer:

Step-by-step explanation:

The ratio is given:

b : r : y = 9 : 6 : 3

Let each equal part be x, then we have:

b - r = 6
9x - 6x = 6
3x = 6
x = 2

Total number of counters:

2(9 + 6 + 3) = 2(18) = 36

Step-by-step explanation:

Let,

Blue counter = 9x

Red counter = 6x

Yellow counter = 3x

Given,

9x = 6x + 6

9x - 6x = 6

3x = 6

x = 6/3

x = 2

Now,

Total number of counter = 2(9) + 2(6) + 2(3)

=> 18 + 12 + 6

=> 36

You are right as rain. You go to the x axis.

Find x = 3.5

f(3.5) is the y value of x = 3.5

f(3.5) = 2

It might help you a bit if you wrote it as a point (3.5,2)

Answer:

$f(x,y)=2x^2+4y^2+2xy=C_1\\\\Where\\\\y(x)=\frac{1}{4} (-x\pm \sqrt{-7x^2+C_1} )$

Step-by-step explanation:

Let:

$M(x,y)=4x+2y\\\\and\\\\N(x,y)=2x+8y$

This is and exact equation, because:

$\frac{\partial M(x,y)}{\partial y} =2=\frac{\partial N}{\partial x}$

So, define f(x,y) such that:

$\frac{\partial f(x,y)}{\partial x} =M(x,y)\\\\and\\\\\frac{\partial f(x,y)}{\partial y} =N(x,y)$

The solution will be given by:

$f(x,y)=C_1$

Where C1 is an arbitrary constant

Integrate $\frac{\partial f(x,y)}{\partial x}$ with respect to x in order to find f(x,y):

$f(x,y)=\int\ {4x+2y} \, dx =2x^2+2xy+g(y)$

Where g(y) is an arbitrary function of y.

Differentiate f(x,y) with respect to y in order to find g(y):

$\frac{\partial f(x,y)}{\partial y} =2x+\frac{d g(y)}{dy}$

Substitute into $\frac{\partial f(x,y)}{\partial y} =N(x,y)$

$2x+\frac{dg(y)}{dy} =2x+8y\\\\Solve\hspace{3}for\hspace{3}\frac{dg(y)}{dy}\\\\\frac{dg(y)}{dy}=8y$

Integrate $\frac{dg(y)}{dy}$ with respect to y:

$g(y)=\int\ {8y} \, dy =4y^2$

Substitute g(y) into f(x,y):

$f(x,y)=2x^2+4y^2+2xy$

The solution is f(x,y)=C1

$f(x,y)=2x^2+4y^2+2xy=C_1$

Solving y using quadratic formula:

$y(x)=\frac{1}{4} (-x\pm \sqrt{-7x^2+C_1} )$

Nine students were asked how many miles they live from school. Their answers are listed below.

Zielflug [23.3K]

Answer: The mode is: 3 . The range is: 6 .
___________________________________
Explanation:
___________________________________
It would be best to list this values in the data set given, from least to greatest:
________________________________________________
{ 3, 3, 3, 3, 4, 5, 5, 6, 9 } .
________________________________________________
The mode is the number that occurs most frequently in the data set, which is: "3".
_________________________________________________________
{The number, "3", occurs FOUR (4) times. The number, "4", occurs ONE (1) time. The number, "5", occurs TWO (2) times. The number, "6", occurs ONE (1) time. The number, "9", occurs ONE (1) time.}.
___________________________________________________
The range is calculated from subtracting the LOWEST value in the data set FROM the HIGHEST value in the data set.
____________________________________________________
The lowest values in the data set is: "3" .

The highest value in the data set is: "9" .
________________________________________________
To calculate the range: 9 − 3 = 6 . The range is: "6".
________________________________________________
Answer: The mode is: 3 . The range is: 6 .
