The second square number is 9 and the fifth is 36
The sum of the numbers is 45
Hope that helps
First you take the 128 and subtract it from 180. You then take the angle that’s vertical from it and place the number (52) and you add 52 + 24 to get 76. After that you take 76 and subtract it from 180 to get 104. X=104
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
