The equationoflinevis y + 10 = 2 3 ( x – 8 ) . line w , which is parallel to line v , includes the point (6, -5) . what is the e

lbvjy [14]

You know that if 2 lines are parallel, they have the same slope.

First, find the slope of the given line;

y+10 = 23(x-8)
y=23x-184-10
y=23x-194

Slope is 23

Write out the basic format;

y=mx+c
y=23x+c <--- replace x and y values here
-5=23(6)+c
-5-138=c
-143=c

Therefore, this equation would be y=23x-143

Hope I helped :)

Answer:

7th term =1

Step-by-step explanation:

This is Geometric progression.

$a_{2}=\frac{a_{1}}{2}=\frac{64}{2}=32\\\\\\r=\frac{a_{2}}{a_{1}}=\frac{32}{64}=\frac{1}{2}\\\\a_{n}=ar^{n-1}\\\\a_{7}=64*\frac{1}{2}^{7-1}=64*\frac{1}{2}^{6}\\\\=64*\frac{1}{64}=1$

7th term =1

The value of the coefficient of correlation ( r) a. can never be equal to the value of the coefficient of determination (r2). b.

gulaghasi [49]

Answer:

d. can be equal to the value of the coefficient of determination (r2).

True on the special case when r =1 we have that $r^2 = 1$

Step-by-step explanation:

We need to remember that the correlation coefficient is a measure to analyze the goodness of fit for a model and is given by:

$r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}$

The determination coefficient is given by $R= r^2$

Let's analyze one by one the possible options:

a. can never be equal to the value of the coefficient of determination (r2).

False if r = 1 then $r^2 = 1$

b. is always larger than the value of the coefficient of determination (r2).

False not always if r= 1 we have that $r^2 =1$ and we don't satisfy the condition

c. is always smaller than the value of the coefficient of determination (r2).

False again if r =1 then we have $r^2 = 1$ and we don't satisfy the condition

d. can be equal to the value of the coefficient of determination (r2).

True on the special case when r =1 we have that $r^2 = 1$
