No its not a good reasonable fit to use a linear regression line. Why not? Because r = 0.15 is closer to r = 0 than it is to r = 1. This is fairly weak linear correlation. If r was say something like r = 0.7 or higher, then it would be stronger linear correlation.

No

Explanation:

<em>It is not reasonable to use the line of best fit to make predictions. </em>

<em> </em>

<em>The correlation coefficient for the data is close to zero. </em>

<em> </em>

<em>The correlation coefficient measures how well a line fits a set of data. </em>

<em> </em>

<em>The correlation coefficient suggests that the relationship between the two variables is weak. </em>

Six posts are evenly spaced along a circular wall encasing a fountain. Anna stands at point A, where she cannot see beyond the o
inn [45]

There are 6 points on a circle.

We have a sum of angles in a circle that is equal to 360°.

Anna can only see 2 points which is a third of a points there are.

That means her spectrum is 360°/3 which is 120°.

The answer is B. 120°.

Hope this helps.

The coordinates for triangle LMN are given below. If Joel plans to transform LMN using the rule (x, y) = (-y, x), which is a tru
Mice21 [21]

Answer:

ok the answer should be A.

Step-by-step explanation:

you transform the coordinates from (x,y) to (-y,x)

this means to flip the coordinates like bring y up front and change its sign and take x to the initial y position.

for example if (-1,9) when you do the transformation you get (-9,-1). you take initial -1 to the right and bring 9 to left and change its sign.

when you are done you can see that the x axis coordinates are the same but the y axis coordinates are the direct opposite. this means that after the transformation the triangle would look like the mirror image of the original triangle.

A 48 inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece
Y_Kistochka [10]

Complete question :

A 48 inch board in to be cut into three pieces so that the second piece is twice as long as the first, and the third piece in 3 times as long as the first. If x represents the length of the first, find the lengths of all three

Answer:

Length of first piece = x = 8

Length of second = 2x = 8*2 = 16

Length of third = 3x = 8 * 3 = 24

Step-by-step explanation:

Let :

Length of first piece = x

Length of second = 2x

Length of third = 3x

The total lengtb of board = 48 inches

Hence,

First + second + third = 48

x + 2x + 3x = 48

6x = 48

x = 48 / 6

x = 8

Length of first piece = x = 8

Length of second = 2x = 8*2 = 16

Length of third = 3x = 8 * 3 = 24
