Answer:
x = 7 and y = 1
Step-by-step explanation:
Coordinates of Coffee shop = (12, 16)
Coordinates of Library = (16, 8)
School has been shifted to the new position so that distance of school is preserved from the coffee shop.
Coordinates of the new position of school = (15, 10)
Ratio in which distance between coffee shop and library is divided by the location of school is x : y.
If a segment having extreme ends and
is divided into two parts by point (x, y) in the ratio of m : n,
x =
y =
From the points given in the picture,
15 =
15x + 15y = 16x + 8y
15y - 8y = 16x - 15x
7y = x
Therefore, x = 7 and y = 1 will be the answer.
Answer:
$134.7088 thousand dollars
Step-by-step explanation:
The given equation of Least Squares Regression Line is
where, is predicted selling price of the house (in thousands of dollars) based on the square footage (in 100 square feet).
We need to find the price of a 3000 square foot house (in thousands of dollars).
3000 = 30 × 100
3000 square foot = 30 square footage (in 100 square feet).
Substitute x=30 in the given equation.
Therefore, price of a 3000 square foot house is $134.7088 thousand dollars.
