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:
5 - 20/0.10 =
Step-by-step explain
20-5 = 15
15/0.10 = 150
150 = 2h and 30min
so he has to use 2h/30min on the phone
Answer:
x= 154°
Step-by-step explanation:
since the interior angle sum of a triangle is 180°, we can subtract the interior angles we already have from 180°
so, 180-108-46= 26° which gives us our missing interior angle.
then, we see the straight line is 180° where we need x.
so, we subtract 26 from 180 which leaves us with 154.
therefore, x= 154°
