Step-by-step explanation:
Inequalities of the type | x | > a, always have solutions of the form
x < - a or x > a
This can be extended to expressions, that is
14 - 5x < - 8 OR 14 - 5x > 8 ( subtract 14 from both sides of both inequalities )
- 5x < - 22 OR - 5x > - 6
Divide both sides by - 5 , reversing the inequality sign as a consequence
x >
OR x < ![\frac{6}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B5%7D)
That is the solution is
x <
OR x > ![\frac{22}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B22%7D%7B5%7D)
Answer:
Step-by-step explanation:
Mean is just another word for average. To find the average, add up all the values then divide by the number of values.
There are 7 values in the first data set. The average is:
(3 + 4 + 6 + 4 + 3 + 1 + 4) / 7 = 25/7 ≈ 3.57
There are 7 values in the second data set. The average is:
(6 + 7 + 2 + 4 + 5 + 5 + 3) / 7 = 32/7 ≈ 4.57
Step-by-step explanation:
Sum of measures of all internal angles of a hexagon is 720°
