Answer:

This is a scatter plot . A scatter plot shows the association between two variables.

The variables in this graph tend to increase and decrease together, this means the association is positive. The straight line describes the relationship between the variables, the association is linear. The association is a linear relationship.

This graph has a wider and more variables/dots around it, meaning that more of the variables are uncorrelated.

This graph also has a few outlier variables.

Find the midpoint of the line segment with the endpoints (1, 0) and (2, -10).

Mariulka [41]

Answer:

$\bigl(\frac{3}{2},-5\bigr)$

or in decimal form

$(1.5,-5)$

Step-by-step explanation:

The midpoint of the line with endpoints $(x_1,y_1)$ and $(x_2,y_2)$ is $\bigl(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\bigr)$ . just take the average between the points

so given the points (1,0) and (2,-10)

$x_1=1$

$y_1=0$

$x_2=2$

$y_2=-10$

the midpoint is found as follows:

$\bigl(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\bigr)$

$\bigl(\frac{1+2}{2},\frac{0-10}{2}\bigr)$

$\bigl(\frac{3}{2},\frac{-10}{2}\bigr)$

$\bigl(\frac{3}{2},-5\bigr)$

or in decimal form

$(1.5,-5)$

One angle of a triangle is three times as large as another. the measure of the third angle is 65 degrees more than that of the s

Sholpan [36]

Let the smaller angle be x.

smaller = x
larger = 3x
known angle = 65°

All angles add up t10 180:
x + 3x + 65 = 180
4x + 65 = 180
4x = 115
x = 28.75

Smaller angle = 28.75
Larger angle = 86.25

Answer: The angles are 28.75° and 86.25°
