picture included , please help, which of the following equations describe the line shown below (1,10) and (-3,2) *check all that

rosijanka [135]

Slope is $\text{m}=\frac{y_1-y_2}{x_1-x_2}=\cfrac{10-2}{1-(-3)}$
Then you use the equation
$\text{y=mx+b}$
Where b is the y-intercept. To find it, plug in x and y from one of the points. Say, point 1 (1,10):
$10=m(1)+b$
You know m (from above) and now you can solve for b.

Rearrange terms:
$y-b=mx$

And that will be the answer.

Make sense?

How do rented housing units differ from units occupied by their owners? Here are the distributions of the number of rooms for ow

IrinaK [193]

Answer:

<u>Standard deviation for owner-occupied units</u>

2.9797

<u>Standard deviation for renter-occupied units</u>

3.1594

Step-by-step explanation:

Let us find first the mean. This is the distribution expected value or expectancy.

<u>Mean for owner-occupied units</u>

0.003 + 2*0.002 + 3*0.023 + 4*0.102 + 5*0.209 + 6*0.223 + 7*0.201 + 8*0.149 + 9*0.053 + 10*0.035 = 6.293

To compute the variance for owner-occupied units, we add these values

$(1-6.293)^2+(2-6.293)^2+(3-6.293)^2+(4-6.293)^2+(5-6.293)^2$

$+(6-6.293)^2+(7-6.293)^2+(8-6.293)^2+(9-6.293)^2+(10-6.293)^2$

then divide by 10 and take the square root to get the standard deviation 2.9797

<u>Mean for renter-occupied units</u>

0.008 + 2*0.027 + 3*0.287 + 4*0.371 + 5*0.155 + 6*0.090 + 7*0.043 + 8*0.013 + 9*0.003 + 10*0.003 = 4.184

To compute the variance for renter-occupied units, we add these values

$(1-4.184)^2+(2-4.184)^2+(3-4.184)^2+(4-4.184)^2+(5-4.184)^2$

$+(6-4.184)^2+(7-4.184)^2+(8-4.184)^2+(9-4.184)^2+(10-4.184)^2$

then divide by 10 and take the square root to get the standard deviation 4.184

Examine the graph

enot [183]

Answer:

<em>The scale factor is 3</em>

Step-by-step explanation:

<u>Dilations</u>

A dilation is a transformation that produces an image that has the same shape as the original but has a different size.

A dilation is described by the scale factor or constant of dilation and the center of the dilation.

We are given a triangle XYZ of coordinates given in the graph to the left:

X=(-1,1), Y=(-1,4), Z=(-2,1)

It was dilated to triangle X'Y'Z' with coordinates:

X'=(-3,3), Y=(-3,12), Z=(-6,3)

Note each coordinate of the dilated triangle is three times the coordinates of the original triangle, thus the scale factor is 3

Find the point, M, that divides segment AB into a ratio of 5:6 if A is at (0.22) and B is at (11.0).

natka813 [3]

Answer:

(5,12)

Step-by-step explanation:

Ratio total =5+6=11

Difference between points

x-x axis from A to B=0-11=-11

y-y axis from A to B=22-0=22

Points from B=6/11(-11,22)=(-6,12)

Point M=Point B+(-6,12)=(11-6, 0+12)=(5,12)

SPARK in Dallas requires a school to send 2 adults for every 20 students who visit for a field trip. If a school send 13 adults,

notka56 [123]

130 would be one trip. if you divide 13 by 2 it is 6.5 and then multiply that by 20 you get 130. please mark me brainliest. have a great day and good luck with school:)
