To determine the variance, we need to first calculate the second moment as follows: The variance can be determined using this equation: The standard deviation is simply the square root of the variance, which gives us the result.

tester [12383]
The recipe uses x cups of white flower together with 6 cups of wheat flower.

Therefore, the combined quantity of flower equals x+6

If y represents that combined amount, the equation to write is:
y=x+6

Constraints are as follows:
y can only be \geq 6

Note that if y = 0 then x would have to be -6, which is not possible.

Answer:

3x = 12

x = 4

Step-by-step explanation:

The equation indicates that the distance to the dance class is three times that to her home, and when multiplied by "x", it reveals how much farther 3 is from 12. Consequently, if you evaluate the expression, the distance to the dance class is four times greater than that to her music class.
