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
Use the KCF method to divide
3/6 / 5/2 = 3/6 x 2/5, which equals 1/5
Hope that helps :)
.22a is the algebraic expression. I hope this helps and have a great day!
Answer:
-4
Step-by-step explanation:
Pick any two points and use the slope function
m = (y2-y1)/(x2-x1)
m = ( -26 - -2)/(2 - -4)
= (-26+2)/(2+4)
- 24/6
- 4
