Answer:
46
Step-by-step explanation:
Since B is the midpoint of AC, the segments AB and BC must have equal length. This means that x + 13 = 2x + 3. Solving this, we see that x = 10. By substituting 10 for x, we see that the length of AB is 23, so the length of AC is 2*23, which is 46.
54+x=12+3x

Answer:
The rate of change represented in the table is 14
Step-by-step explanation:
rise over run or y2-y1/x2-x1 to find the rate of change
pick two points
lets use (0,-11) and (2, 17)
17 - (-11) / 2 - 0
= 28 / 2
= 14
The 99.87th percentile, or the area to the left of the 3 standard deviation mark it 99.87% better than everyone/everything else.
