Re-expressing data means making the facts more appropriate for evaluation by our methods.

We can not use a linear version until the connection among the 2 variables is linear. Often re-expression (transformation) can save the day, straightening bent relationships in order that we are able to suit and use a easy linear version.

• Two easy approaches to re-specific facts are with logarithms and reciprocals.

• Re-expressions may be visible in regular life— all and sundry does it.

We can re-specific gas performance as gallons in step with hundred miles (a reciprocal) and get rid of the bend in the authentic scatterplot.

Therefore, re-expressing data means making the facts more appropriate for evaluation by our methods.

The simplified expression is:

[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)[/tex]

[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a[/tex]

do you want a graph?

Step-by-step explanation:

x is -0.5

y= 2

Answer:

y=5x+11

Step-by-step explanation:

using point-slope equation, we substitute.

parallel lines have the same slope.

y-y¹=m(x-x¹)

y-6=5(x+1)

y-6=5x+5

y=5x+11

(please comment if you're confused on anything!)

Answer:

Find the equation of a line given that you know a point of point on the line in the slopes the equation of the line is typically written as y=mx+b where am is slope and b is the y- intercept

The m variable is the slope of the line and controls its 'steepness'. A positive value has the slope going up to the right. A negative slope goes down to the right. The b variable is the y intercept - the point where the line crosses the y axis.

example 1                                                    

y = mx + b

m = slope b = y-intercept

y = 3x - 1

m = 3 and b = -1

example 2

y = b + mx

b = y-intercept m = slope

y = 5 - 1/2x

m =- 1/2 and b = 5

Step-by-step explanation:

The Buddha taught that just as individual states had laws, there was a universal law. Each person's station in life was a reflection of their karma, or the cumulative extent to which they had followed or broken the universal law in previous lives.  Chinese leaders began to appoint skilled bureaucrats rather than solely employing hereditary officeholders, and Confucian thinkers held that people became fully developed members of society through a process of education, rather than simply by noble birth.

Answer:

y = -9/8x +7

Step-by-step explanation:

We know two points on the line so we can find the slope

m = ( y2-y1)/(x2-x1)

m = ( -2 -7)/(8 -0)

  = -9/8

We also know the y intercept which is 7

The slope intercept form of the line is

y = mx+b where m is the slope and b is the y intercept

y = -9/8x +7

Answer:

[tex]y=-\frac{9}{8}x+7[/tex]

Step-by-step explanation:

Slope-intercept form is y=mx+b

Use the formula for slope: m=(y2-y1)/(x2-x1)

m=(-2-7)/(8-0)

m=-9/8

The graph shows that b, the y-intercept, is at (0,7)

Therefore, the final equation is [tex]y=-\frac{9}{8}x+7[/tex]

Answer:

The standard deviation of the weight, σ, is approximately 4.73 kg

Step-by-step explanation:

The weights of the six puppies are;

[tex]x_i[/tex] = 1, 2, 7, 7, 10, and 15

The number of puppies, n = 6

Therefore, we have;

The mean = μ = ∑x/n = (1 + 2 + 7 + 7 + 10 + 15)/6 = 7

The standard deviation, σ, is given as follows;

[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{n}}[/tex]

By substituting, we have;

[tex]\sigma =\sqrt{\dfrac{ \left (1-7 \right )^{2} + \left (2-7 \right )^{2} + \left (7-7 \right )^{2} + \left (7-7 \right )^{2} + \left (10-7 \right )^{2} + \left (15-7 \right )^{2} }{6}}[/tex]

Simplifying gives;

[tex]\sigma =\sqrt{\dfrac{ \left (-6 \right )^{2} + \left (-5 \right )^{2} + \left (0 \right )^{2} + \left (0 \right )^{2} + \left (3 \right )^{2} + \left (8 \right )^{2} }{6}} =\sqrt{\dfrac{ 36 + 25 + 0 +0+ 9 + 64 }{6}}[/tex]

[tex]\sigma =\sqrt{\dfrac{ 134 }{6}} = \sqrt{\dfrac{67}{3} } \approx 4.72582[/tex]

The standard deviation of the weight, σ ≈ 4.73 kg to two decimal places.

Answer:

36

Step-by-step explanation:

Let the required number be x.

[tex] \frac{1}{3} \: of \: x = \frac{1}{3}x = \frac{x}{3} \\ \\ \frac{1}{4} \: of \: x = \frac{1}{4}x = \frac{x}{4} \\ \\ according \: to \: the \: given \: condition \\ \\ \frac{x}{3} - \frac{x}{4} = 3 \\ \\ \frac{4x - 3x}{3 \times 4} = 3 \\ \\ \frac{x}{12} = 3 \\ \\ x = 12 \times 3 \\ \\ \huge \red{ \boxed{ x = 36}}[/tex]

The number is 36.

Given that,

Based on the above information, the calculation is as follows:

Step-by-step explanation:

I think x=-2

The value of x is 11. Then the length of the line segment PR, PQ, and QR will be 52, 30, and 22, respectively.

An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two factors determine a line, two points are transparently collinear. If the points are in a line, then the points are collinear points.

Let A, B, and C be the collinear points. Then the condition of the collinear will be

AB + BC = AC

PQ = 2x + 8, QR = x + 11, and PR = 5x - 3.​ From the figure, the points P, Q, and R are the collinear points. Then we have

PQ + QR = PR

2x + 8 + x + 11 = 5x - 3

3x + 19 = 5x - 3

22 = 2x

x = 11

Then the line segment PR, PQ, and QR will be

PQ = 2 × 11 + 8

PQ = 22 + 8

PQ = 30

QR = 11 + 11

QR = 22

PR = 5 × 11 - 3

PR = 55 - 3

PR = 52

The value of x is 11. Then the length of the line segment PR, PQ, and QR will be 52, 30, and 22, respectively.
