Step-by-step explanation:
The regression line has the following format:
In which b is the slope(how much each mile costs) and a is the fixed number of miles flown.
In this problem, we have that:
. So
A person who spent $ 2000 is predicted to have flown:
This is y when x = 2000.
So the correct answer is:
c) 44000 miles

The guessed weight is 120 pounds,
Thus,
⇒
⇒ (by multiplying 3 on both sides)
⇒
⇒
⇒ ( On dividing both sides by 3 )
Answer:
AB = 8/ cos 60
Step-by-step explanation:
We want to find the hypotenuse AB
Since we have a right triangle
cos theta = adj/ hyp
cos 60 = 8/ AB
AB cos 60 = 8
AB = 8/ cos 60
