Suppose a normal distribution has a mean of 12 and a standard deviation of 4
a value of 18 is how many standard deviations away from the mean?
a -2
b -1.5
c 1.5
d 2

The correct answer is C. 1.5

Step-by-step explanation:

To find this, first find the difference from the value to the mean.

18 - 12 = 6

Now that we have this, divide it by the size of a standard deviation to find how many it is away.

6/4 = 1.5

lol

step-by-step explanation:

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
