Answer:
Step-by-step explanation:
If your mind works better in degrees than it does radians, as does mine, it will be beneficial to us to see what degree measure this angle is. Convert it to degrees using the fact that 180° = π:
degrees
Now that we know that, we can plot that angle in a coordinate plane. The terminal side of the angle lands in quadrant 2. To find the reference angle, we subtract 120 from 180 and get that the reference angle is 60 degrees, which is the same as π/3.
Answer:
A) m = 0.062
B) 202.87 thousand dollars
C) Original price = 116.07 thousand dollars. $6000 is called the error term.
Step-by-step explanation:
We are given the following in the question:
Price = 47.87+0.062(size)
The above equation is regression equation where price is in thousand dollars and size in square feet.
Let p be the prize and s be the size.
Comparing it to linear equation, we have,
where m is the slope and c is the y-intercept.
m = 0.062
c = 47.87
A) slope of the line
The slope of line tells the rate of change. Thus, it tells the change in price if the size of house is increased by 1 square feet.
The price of house increases by 0.062 thousand dollars if the size of house is increased by 1 square feet.
B) Price of house
We are given s = 2500. Putting this value in the equation.
Thus, the price of a 2500 square feet house is 202.87 thousand dollars.
C) We are given s = 1100
Putting the value in the equation:
Original price = 116.07 thousand dollars
Asking price =
The buyer is asking for 110.07 thousand dollars.
$6000 is called the error term.
