Answer:
iii. priceof a house in Saratoga, N.Y.
Step-by-step explanation:
In this question, we take a sample from house prices of 1728 houses in Saratoga, New York.
Since only houses from Saratoga are part of the sample, the response variable will be related only to Saratoga.
In this question:
Sample to find house prices in Saratoga, which is the variable of interest. The correct answer is given by option iii.
There's a lot of information missing here, and the given list of choices is basically incomprehensible.
Suppose J (a, b) and K (c, d) are two points in the plane. We can trace out the line segment JK joining these points with the function
r(t) = (1 - t) (a, b) + t (c, d)
where 0 ≤ t ≤ 1.
Let P be the point that divides JK into line segments JP and PK having a length ratio of 2:5. Then JP is the point 2/7 of the way along JK, so that the coordinates of P are
P = r(2/7) = 5/7 (a, b) + 2/7 (c, d) = ((5a + 2c)/7, (5b + 2d)/7)
and in particular the x-coordinate of P is (5a + 2c)/7.
Did you find the answer? I could use the help with it too.
