A mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other
Answer:
13.4 inches
Step-by-step explanation:
Firstly you should calculate the diagonal of lower square using pythahoras theorem
I.e diagonal = (89)^1/2
Now calculate distance by simple arithmetic
X=Xx + Xy
= (89)^1/2 + 4
= 13.4
Elevation per minute
elevationchange=-8212
timechange=214
elevation per minute=-8212/214=
-8132/214-80/214=
-38-40/107=
-38 and 40/107
answer is -38 and 40/107 ft per minute
Answer:
Option d.
Step-by-step explanation:
The equation of the line of least squares is given as

where
is the yield of wheat (bushels per acre) and x is the rainfall (in inches).
We need to find the expected number of inches of rain if the yield is 60 bushels of wheat per acre.
Substitute
in the given equation.

Add 9.12 on both sides.


Divide both sides by 4.38.


The expected number of inches of rain is 15.78.
Therefore, the correct option is d.
