Answer:

The Regression line is that line , which passes through all the points , through a single point , or none of the points.

Here, the table is about ,weight of a dog in pounds at various ages in months.

The ratio of Weight at different stages,of months should be proportional.

So, if you look at option (1) , the ratio of x to y in three cases are same that is

\frac{4}{5}=\frac{8}{10}=\frac{12}{15}

It means Regression line is Passing through three points, means Dog's weight  at three different stages of month are same.and in other tables the ratio are not equivalent.

So, Table 1, that is option 1

is true.

x: 3, 4, 6, 8, 9, 12

y: 2, 5, 7, 10, 11, 15

Which equation can you use to solve for x​
svet-max [94.6K]

As for a specific equation, I could not say. However, I can tell you how to find x!

The first thing to remember is that a straight line has a 180 degree angle.

You see on the bottom side that we have a 146 degree angle. Now look at the top side. Look closely, and you will see that the two sides are actually identical!

Don't see it? Look at the line on top between x and 56, and imagine it is not there. You see that we actually have the same 146 degree angle, just flipped right side up!

However, this angle does not say 146, but makes an extra line between them with x and 56. This means that x + 56 equals 146!

So we can find x by subtracting 56, from 146, which is... 90!

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ
Nata [24]

Answer: 5x-3y=44

Step-by-step explanation:

We know that , the equation of a line that passes through (a,b) and (c,d) is given by :_

(y-b)=\dfrac{d-b}{c-a}(x-a)

Standard form of equation of line = Ax+By=C

Given points =  (7, -3) and (4, -8)

Then, the equation of a line that passes through the points . (7, -3) and (4, -8) is given by -

(y-(-3))=\dfrac{-8-(-3)}{4-7}(x-7)

(y+3)=\dfrac{-8+3}{-3}(x-7)   [∵ (-)(-)=(+)]

(y+3)=\dfrac{-5}{-3}(x-7)

(y+3)=\dfrac{5}{3}(x-7)

3(y+3)=5(x-7)

3y+9=5x-35

9+35=5x-3y

44=5x-3y

Or 5x-3y=44

Hence, the required equation :-5x-3y=44

Answer:

NCA = GRU

Step-by-step explanation:

Since triangle CAN = triangle RUG

This means

C=R

A=U

N = G

We can change the order of the letters for the triangle in the first, but then they have to be corresponding in the second

ANC = UGR

NCA = GRU

ACN = URG

CNA= RGU
