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.
Answer:
B
Step-by-step explanation:
To evaluate (f ￮ g)(- 4), first evaluate g(- 4) then substitute this value into f(x)
g(- 4) = 3(- 4) - 5 = - 12 - 5 = - 17, then
f(- 17) = 4(- 17) + 7 = - 68 + 7 = - 61 → B
C) 80,360 you multiply the number of cases by the number of pastries in each case.
Step-by-step explanation:
you need more information
Consistient means they have countable number of solutions (example, a point, not a line since lines are infinite)
inconsitient means they have no solutions (no points of intersection)
dependent means that they have infinite solutions (most likely becasue they are the same equaiton)
6x-2y=10
9x-3y=9
divide first equation by 2
3x-y=5
multipliy by -3
-9x+3y=15
add to second equation
-9x+3y=15
<u> 9x-3y=8 +</u>
0x+0y=23
0=23
fales
therfor it is inconsistient
