Answer:
B -0.104
Step-by-step explanation:
Step 1: Write the formula for correlation
r = total xy
√Total x² x Total y²
Step 2: Make a table to calculate all values
Table is attached in the picture below
Step 3 : Solve
Mean of X = Total X/ Total number of X
= 507/12
= 106.33
Mean of Y = Total Y/ Total number of Y
= 1276/ 12
= 42.25
r = total xy
√Total x² x Total y²
r = -352.05/ √3656.25 x 3122.66698
r = -0.104
-0.104 is negative
This negative correlation means there is an inverse correlation between variables.

Answer:
12+x
Step-by-step explanation:
This is marli- []
|
/\
Marli is 12
but lets say that Marli's brother is 5 yrs older than her just for fun
To find marli's bro's age when her bro is 5 yrs older than her, we would add 5 and 12 right?
the same thing applies when there's a variable in place of a number
DO NOT GET CONFUSED, DO EXACTLY THE SAME THING IF THERE HAD BEEN A NUMBER INSTEAD OF A VARIABLE
so
marli's bro= 12+x
Hope This Helps!!!!!
