Answer:
The correlation between sales and advertising is positive.
Step-by-step explanation:
For every $35 spent on advertising, sales increase by $1
Is FALSE, since y = 500 + 35 x $35, sales increase more than $1
Even if no money is spent on advertising, the company realizes $35 of sales
Is FALSE, if no money is spent, the sales amount to $ 500 (when X = 0)
The coefficient of correlation between sales and advertising is 0.81
Is FALSE, since R² = 0.9. The coefficient of correlation = R = 0.94, not 0.81
Answer:
136
Step-by-step explanation:
No matter what the distribution, all of the interior angles of a convex hexagon will add up to 720 degrees. Therefore, if you subtract all of the known angles in this hexagon from 720, you will find x.
720-134-106-117-119-108=136 degrees. Hope this helps!
Answer:
the first one
Step-by-step explanation:
The first equation is -5m+15
and the first one is 15-5m
Which is basically the same thing.
Glad to help
Answer:
x=9
JKL = 108 degrees
KLJ = 27 degrees
LJK = 45 degrees
Step-by-step explanation:
Add all the values of the triangle angles together to get 20. Then divide 180 by 20 to get 9 (The sum of all the angles in the triangle always equals 180 degrees).
JKL = 12x = 12(9) = 108
KLJ = 3x = 3(9) = 27
LJK = 5x = 5(9) = 45
