19. Real estate redux. The regression of Price on Size of homes in Albuquerque had R2 = 71.4%, as described in
Exercise 15.
a) What is the correlation between Size and Price?
Explain why you chose the sign (+ or -) you did.
b) What would you predict about the Price of a home 1
standard deviation above average in Size?
c) What would you predict about the Price of a home 2
standard deviations below average in Size?

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
