The correct answer is B)y=2x-6
Answer:
Option B.
Step-by-step explanation:
Given information:
Σ(x − M) = 44
where, M is mean.
Sample size = 12
The computational formula for sample variance is

where, M is sample mean and N is sample size.
Substitute Σ(x − M) = 44 and N=12 in the above formula.



The sample variance is 4.0.
Therefore, the correct option is B.
The correct answer is 6*10^-6 ..........................
Answer:
450 x 15 = 6750 ft 2
Step-by-step explanation:
Answer: x = -5 and y = -5
Step-by-step explanation:
They drew the linear graph for the simultaneous equations on the graph already
The answer the the equations is the intersection of the lines which is (-5,-5) or x = -5 and y = -5
