Marna's utility bills over the last year have a mean of $89.10 and a standard deviation of $5.13 . This month her bill has a of 1.65 How much was her utility bill? A.$97.56
B.80.64
C.94.23
D.83.97

i am sure it will be 90 degrees.

step-by-step explanation:

if this is really you s much. i only have 3 points left and i have 2 questions to ask

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

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
