It’s still 6 because adding a constant does not change the standard deviation.

Answer: I believe the standard deviation will remain the same, 6, choice A.

Step-by-step explanation: Standard deviation is calkculated based on the difference of each point from the mean. If 10 were added to each score, the mean would also increase by 10. That would mean that the difference between the mean and each score would be exactly the same, leading to an identical standard deviation. Sounds crazy, but that's what numbers do for a living.

Solve for x: |3x + 12| = 18

Alla [95]

Answer:

X = 2 or X = -10

Step-by-step explanation:

We know either3x+12=18or3x+12=−18

3x+12=18(Possibility 1)

3x+12−12=18−12(Subtract 12 from both sides)

3x=6

(Divide both sides by 3)

x=2

3x+12=−18(Possibility 2)

3x+12−12=−18−12(Subtract 12 from both sides)

3x=−30

−30

(Divide both sides by 3)

x=−10

Answer:

x=2 or x=−10

Nonamiya [84]

Answer:

$\dfrac{-1}{2}$

Step-by-step explanation:

We need to find ration numbers between -1 and 1.

Multiplying and dividing both -1 and 1 by 2.

$\dfrac{-1\times 2}{2}=\dfrac{-2}{2}$

and $\dfrac{1\times 2}{2}=\dfrac{2}{2}$

Now, the rational number between -2/2 and 2/2 is $\dfrac{-1}{2}$ .
