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:
31.5 hours
Step-by-step explanation:
time * speed = distance
speed=400/6=66.67 miles per hour
2100/(400/6)=31.5 hours
The distance between two points is the number of units between them
The distance between the oak tree and the maple tree is 9 yards
<h3>How to determine the distance?</h3>
From the diagram, we have the following highlights:
- The distance between the maple tree and the end is yards
- The distance between the oak tree and the end is yards
The distance (d) between the oak tree and the maple tree is the difference between the above measurements.
So, we have:
Simplify the expression in the bracket
Subtract
Hence, the distance between the oak tree and the maple tree is 9 yards
