Answer:
827 ÷ 4 = 206 with a remainder of 3
Step-by-step explanation:
So I guess we are solving for x here :)
So here is my work...
a=2x+6xz
Basically I think it would be
a=6xz+2x
WAIT WAIT NO I'M WRONG FORGIVE ME!
It's x=a/2(1+3z)
869 * .08 = 69.52
69.52 + 869 = 938.52
938.52- 75 = 863.52
The point lies directly on the regression line (Apex)
