Answer:

yes

Step-by-step explanation:

any shape that is duplicated to another area on a graph is a translation

Answer:

No, the two figures are oriented differently.

Step-by-step explanation:

It's actually a reflection and then a translation! The thing is that the figure is reflected over the y-axis and then translated, and we know this because the points have switched places and the shape moved up! :)

Consider a population list x, with a CV= 10%. A second population list, y, has a CV= 20%. The linear regression of y on x is y =

ch4aika [34]

Answer:

The correlation coefficient 0.5 depicts that there is moderate positive correlation between y and x.

Step-by-step explanation:

The linear regression equation is

y= a+bx

The given linear equation is

y= 10x

Here, slope=b=10 and intercept=a=0.

From above equation,

ybar=10xbar

We are given that CVx=0.1 and CVy=0.2

where CV=(standard deviation/mean)*100

We know that

b=r(Sy/Sx)

Multiplying by xbar/ybar on both sides

(xbar/ybar)b=r(Sy/Sx)(xbar/ybar)

(xbar/ybar)b=r[(Sy/ybar)/(Sx/xbar))]

(xbar/ybar)b=r[CVy/CVx]

As CVy/CVx=(Sy/ybar)*100/(Sx/xbar)*100=(Sy/ybar)/(Sx/xbar).

By putting ybar=10xbar, b=10, CVx=0.1 and CVy=0.2.

(xbar/10xbar)10=r(0.2/0.1)

1=r(0.2/0.1)

1=r(2)

r=0.5

There is moderate positive correlation between y and x.

Write an equation in slope-intercept form for the line that is parallel to y = −4x − 3 and that passes through the point (−2, 4)

Neporo4naja [7]

Since it's parallel, then the slope is the same
use the point slope formula and plug in the slope and point
y-y1=m(x-x1)
y-4=-4(x+2)
y-4=-4x-8
y=-4x-4
this is in slope intercept form

5 and three tenths - 2 and five tenths

torisob [31]

5 and three tenths translates to 5.3 and 2 and five tenths translates to 2.5... 5.3 - 2.5 = 2.8

2.8 translates to 2 and 8 tenths which can be simplified to...

2 and 4 fifths

Fill in the table of values for y=2-x<br> X/ -3 0 5<br> Y

victus00 [196]

Answer:

I put in y = 2-x. I believe that was the equation you asked a table for. If it is another equation please tell me or just download or look up Desmos. Desmos helps create graphs and tables. I hope this helps. Have a great rest of your day!
