Answer:
Step-by-step explanation:
This is about sums.
Use the numbers in the table to find respective sums.
1. Sum of all fi
- ∑fi = 3 + 5 + 7 + 8 + 12 + 10 = 45
2. Sum of all xi
- ∑xi = -2 + 5 + 4 - 3 + 7 + 6 = 17
3. Sum of all yi
- ∑yi = 3 + 3 - 7 + 2 - 5 - 1 = - 5
4. Sum of fi*xi
- ∑(2 to 4)fi*xi = 5*5 + 7*4 + 8*(-3) = 29
5. Sum of (xi + yi)
- ∑(1 to 3)(xi + yi) = (-2 + 3) + (5 + 3) + (4 - 7) = 6
Answer: m (the slope) = 1/7
Step-by-step explanation:
The slope formula is attached. When you plug in the numbers, you get 1/7 -
0 - 1 / -7 - 0
