Indirect material cost: y
explained by units produced: x
Linear regression. Cost estimation equation: y=mx+b
Constant: b=$15,640
Standard error of y estimate=$3,600
r^2=0.7704
Number of observations: n=22
x coeffient: m=11.25
Standard error of x coefficient=2.19
m=11.25, b=15,640 → y=11.25x+15,640
Answer: The cost estimation equation is y=11.25x+15,640
Answer:
In the second step, the +16 should be -16
In the 3rd step, you should add 16 instead of subtracting 16
m=0
Answer:
No solution
Step-by-step explanation:
-3x-9=-3x-3-5
-3x-9=-3x-8
-9=-8
Answer:
C.Tammy’s estimate is right, but the actual product should be 24.78.
