Answer:
A: 171.75
B: 170
Step-by-step explanation:
The mean (or average) can be found by...
- add all the numbers together (we will call this y)
- divide the total sum (or y) by the total amount of numbers used to add
Formula:
(x₁ + x₂ + x₃ + ... + xₙ) ÷ n
For A:
(172 + 130 + 173 + 212) ÷ 4 = 171.75
For B:
(136 + 184 + 168 + 192) ÷ 4 = 170
Answer: 5
Step-by-step explanation:
AE is half of AC
2 (x + 2) = 5x - 11
2x + 4 = 5x - 11
+ 11 + 11
2x + 15 = 5x
- 2x - 2x
15 = 3x
/ 3 / 3
x = 5
