Answer:

x = 1

Step-by-step explanation:

3(x+2) - 4 = -(x-6) | Given

3x + 6 - 4 = -x + 6 | Distribute.

On the right side, where there is a minus on the outside of the parenthesis you can assume there is a 1. Flip the signs and multiply everything inside by -1.

3x + 2 = -x + 6 | Add the numbers

3x = -x + 4 | Subtract 2 from both sides

4x = 4 | Add x to both sides

x = 1 | Divide both sides by 4.

Sunny_sXe [5.5K]

Answer:

Option B.

Step-by-step explanation:

The given data set is

34, 35, 41, 28, 26, 29, 32, 36, 38, 40

We need to find the mean deviation of the given data.

Number of observations, n = 10

Mean of the data is

Mean=\dfrac{\sum x}{n}

Mean=\dfrac{34+35+41+28+26+29+32+36+38+40}{10}

Mean=\dfrac{339}{10}

Mean=33.9

Formula for mean deviation is

\text{Mean deviation}=\dfrac{\sum |x-mean|}{n}

\sum |x-mean|=|34-33.9|+|35-33.9|+|41-33.9|+|28-33.9|+|26-33.9|+|29-33.9|+ |32-33.9|+|36-33.9|+|38-33.9|+|40-33.9|=41.2

\text{Mean deviation}=\dfrac{41.2}{10}

\text{Mean deviation}=4.12

The mean deviation of the ratings is 4.12.

Therefore, the correct option is B.
