3,4,6,3,2,5,6,1,12,8,3,2 calculate the mean

The mean is the average.

Add all the numbers together than divide by the amount of numbers there are:

3 + 4 + 6 +3 + 2 + 5 + 6 + 1 + 12 + 8 + 3 + 2 = 55

there are 12 numbers.

Mean = 55 / 12 = 4.583

Round the answer as needed.

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
