Suppose a population consists of 85,000 people. Which of the following
numbers of members of the population being surveyed could result in a
parameter but not a sample statistic?
A. Neither 850 nor 85,000

B. 85,000

C. 850

D. Both 850 and 85,000

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
