\qquad \qquad\huge \underline{\boxed{\sf Answer}}

Let's solve for x ~

\qquad \sf  \dashrightarrow \: 5(2x + 4) = 15

\qquad \sf  \dashrightarrow \: (5 \times 2x) + (5 \times 4) = 15

\qquad \sf  \dashrightarrow \: 10x + 20 = 15

\qquad \sf  \dashrightarrow \: 10x + 20 - 20 = 15 - 20

\qquad \sf  \dashrightarrow \: 10x =  - 5

\qquad \sf  \dashrightarrow \:  \dfrac{10x}{10}  =  \dfrac{ - 5}{10}

\qquad \sf  \dashrightarrow \: x =   - \dfrac{ 1}{2}

hence value of x is - 1/2

So you know: 
1) There are 180° in a triangle.
2) A straight line is also 180°.
So the three angles in the triangle are 
2x, 103-x, and (180-(6x-7)).
Solve for x!
2x + 103-x + (180-(6x-7)) = 180
2x + 103-x + 180-6x+7 = 180 
-5x = -110
x = 22

A) it is left skewed
B) the median is 5
C) the mean is 5.15
D) the mean would be more affected (a change of 1.05 versus a change of 0.5).

The majority of the data is to the right of the graph; this means it is left skewed.

To find the median, write all of the data values out:
2, 3, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7

The middle value is 5.

We find the sum of this set of values and divide by 13, the number of data points, to find the mean:
2+3+4+4+5+5+5+6+6+6+7+7+7 = 67/13 = 5.15

If we added an additional data value at 20, the new median would be 5.5.  The new mean would be (67+20)/14 = 6.2.  The mean changes more than the median.
