Apolling organization is checking its database to see if the data sources it used sampled the same zip codes. the variable datasource equals 1 if the data source is metromedia, 2 if the data source is dataqwest, and 3 if it's rolling poll. the organization finds that the correlation between five-digit zip code and datasource is minus0.0229. it concludes that the correlation is low enough to state that there is no dependency between zip code and source of data. comment.

50=33x+22

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

(x, y)→(x − 8, y − 7)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
